Ore Analysis

Proven mining technology at work for you The core of our recovery equipment is comprised of two highly efficient concentrators, our Low-G Horizontal Centrifuge (primary concentrator), and our Reverse Multi‐Helix Spiral. These revolutionary heavy metal/mineral concentrators were developed based on the need to recover a high percentage of fine gold in large production volumes, with greater recovery ability than traditional sluices, yet with a simpler mechanical apparatus versus pulsating jigs or centrifugal bowls. Thus, the Horizontal Centrifuge was perfected for high volume, primary recovery of fine gold, and the Reverse Multi-Helix Spiral as a rougher, cleaner, and finisher. Both are simple to operate and can be connected in parallel to expand volume throughput. Their simplicity, versatility, and efficiency are unique in the industry. Oro Industries Inc. provides expert consulting, custom fabrications, on-site piloting capabilities for the design and fabrication of production-scale plants, and complete mobile equipment packages for your application. We are the mining company for miners! We look forward to contributing our expertise to your project.

RUGGED AND PROVEN EQUIPMENT SPECIFICALLY DESIGNED FOR THE MINING INDUSTRY

100 Yard/Hour Mobile Placer Plant (MPP-100)

Multi Helix Spiral The Reverse Multi-Helix Spiral Concentrator is available in 3 models: the 24” Rougher, the 16” Cleaner, and the 16” Finisher. Each concentrator can be set up as a continuous or batch feed. All units are commercial duty, gravity concentrators for both alluvial and fine milled hard rock ores. Oro’s Helix Spiral concentrators can achieve the highest concentration ratio AND recovery possible with any type of ore that can be concentrated by gravity. The design and engineering principles of the multi-helix spirals inside the concentrator allow for full adjustment to the ore-matrix or concentrate, yielding the peak concentration ratio with virtually no loss of gold. With this unique ability, it means higher production rates, and a reduced amount of concentrate resulting in a smelting grade concentrate or finished clean gold. The Helix Spiral can be setup in parallel, series, or as a stand-alone concentrator; in parallel for higher production rates, in series for mixed minerals, and stand-alone for pure gold recovery. The configurations are unlimited. Moreover, by using a 24” Rougher to feed a 16” Cleaner, and the cleaner feeding a 16” Finisher will put clean, sellable or smelt-grade gold in your hand, without anyone touching it. Cleaner Model Spiral Concentrator A continuous or batch feed secondary concentrator for processing primary sluice concentrate, primary jig concentrate, centrifuge concentrate, and milled hard-rock ores. Set up as a cleaner, the 16” or 24” spiral concentrator is perfect for the application of mercury recovery and tailings projects. For highest production performance, it is recommended to classify material to 1/4” minus.

Finisher Model Spiral Concentrator The finisher model can be used in conjunction with our standard Secondary Cleaner to shorten clean-up time when concentrating large volumes, or in certain custom applications. Highest production performance is with fine concentrates of materials less than 1/8”. Up to 90% of all concentration and clean-up needs can be achieved with the standard 16” Secondary cleaner. Ask us for advice about your particular application.

The actual "working surface" of the concentrator is made up of a series of leads running lengthwise “in reverse” in a critical tight spiral pattern along the inner barrel. The leads have a set angle on the uphill side and a counter angle on the downhill side, and are larger in height and width at the rear of the barrel than at the front. Exact angles and dimensions to create ultimate efficiency took hundreds of hours of trial and error testing. During operation, the decreasing height and width of the leads create the classifying effect as the ore es through the barrel. As the ore is being classified, the gold and heavy concentrate settle into the bottom of the groves made by the leads and is conveyed upwards (in reverse). As the classified ore reaches the upper portion of the barrel, a set of angled spray heads continuously “wash back" the lighter gangue material while the gold and heavy concentrate continue moving forward, falling out of the groves and into the concentrate holding bin. This is a continuous process allowing the gold concentrate to be recovered in a hands off fashion while the waste is being discharged out of the rear of the Spiral. For larger volume processing, multiple Spirals can be installed in "series" with the ore being feed automatically from one Spiral to the next.

VERSATILITY

24” Rougher Model Spiral Concentrator Used as a Primary Concentrator for both alluvial and milled hard rock ores, the 24” Spiral is ideally suited for mixed mineral hard rock ore concentration. This concentrator can’t be beat when the job calls for a continuous concentrator for Gold, Glena, Chalcopyrite and Sulfide type hard rock ores. As well replaces Jigs for heavy black sand ores. Fine gold recoverable ability + 90% to 200 mesh in production and 99% above 140 mesh.

We stock all spirals and can ship same day as order confirmation!

For secondary and final processing of sluice concentrates, primary jig concentrates and centrifuge concentrates - fully adjustable allowing for "rough" and/or "tight" cuts, adjusts to a wide range of ores and concentrates to achieve a smelting grade product - also great for bulk sampling and testing head ores continuous feed or batch feed portability allows you to move around your site or work off site (indoors or outdoors) - classify any heavy metal or heavy mineral such as gold, silver, platinum, tantalum barite, scheelite, sulfides, tin, galena, lead shot and bullets etc. The spiral is also great for recovery of mercury and tailings projects. All considered, the Helix Spiral is the most versatile and practical piece of mining equipment you will ever own!

Low-G Horizontal Centrifuge Primary Concentrator “If you can’t see it with the naked eye, the Low-G Centrifuge will recover it." A “skilled panner” can recover free gold down to 100 mesh and our Low-G Centrifuge has equal ability for free gold recovery. However, in a production environment, recovery rates using gravity separation methods for gold particles down to 200-300 mesh, begin to decline with any gravity separation method. We claim 99% recovery of free gold down to 100 mesh and 80% to 90% recovery down to 200 mesh. Recovery rates of free-gold particles at 300 mesh minus start getting out of reach of physical concentration means and require chemical separation methods. Gold measuring in the 300 mesh range is almost colloidal and tends to stay in suspension in the turbid water. Even in clear water, this ultra fine gold stays in suspension almost indefinitely in a production environment. Claims of high recovery rates of 300 mesh gold in a production environment using physical (gravity) means are simply not true.

Oro Industries Low-G centrifuges are available in 3 sizes: the 16”, 24” and the 30”. All Low-G Centrifuges are Primary batch-type concentrators for both alluvial and milled hard rock ores. They are designed and engineered for commercial continuous duty and are bullet proof. The Low-G has the ability to recover finer gold at a higher recovery rate than any other concentrator on the market today. The reason for this is that the Low-G is a centrifugal concentrator not a gravity concentrator. That means it’s not reliant on gravity settlement; the values are forced into the concentrate chambers by centrifugal force. This yields a greater recovery of fine gold. Since the Low-G is a batch-type concentrator, you can achieve very high concentration ratios with most types of alluvial and hard rock ores. In fact, you achieve a much greater ratio then any gravity concentrators are capable of producing. In most cases you can run all day before you retrieve the concentrate from the centrifuge. To retrieve the concentrates, simply slow down the centrifuge and all of the concentrate will come out within 30 minutes. After a whole day of production this concentrate is rich, so be careful how you handle it. The best way is to process it with Oro’s Multi-Helix Spiral Cleaner & Finisher. The Spiral’s are designed to take the centrifuge concentrate and give you fine, clean, free gold, at the highest recovery rate possible. Setup and operation of the Low-G centrifuge easy. It needs to be on a level surface of wood, steel or cement. Each centrifuge has a standard pipe flange feed connection, and comes with a swing discharge trough. The trough is down when running production and you swing it up to retrieve the concentrate into a receiving bin. To operate the centrifuge, set the running speed to its indicated running RPM value located above the tachometer by turning the speed control knob. Start the water flow and begin feeding the ore. When you are ready to retrieve the concentrate, place a receiving bin under the discharge trough. Stop ore feeding, slow down the water to around 25 GPM, and let it run at full RPM for 10 minutes. This will clean out excess material away from the concentrate. Swing up the discharge trough and start slowing down the centrifuge by turning the speed control knob. Lower the RPM’s in increments of 100 every 5 minutes. At half the running speed you’ll start to see the heaver concentrate and gold beginning to discharge. Keep slowing down the centrifuge by increments of 50 RPM’s every few minutes until you reach 200 RPM. At that speed all the concentrate will come out in 10 to 15 minutes.

The Centrifuge is a low G-Force, batch type Concentrator, designed to operate with clean or turbid water, which makes it ideal for recycle / recirculation applications. It is a continuous feed (water and ore) Concentrator and “batches” the concentrate during the run process. In operation at a specific G-Force, the internal chambers fill with lighter material, which form soft fluidized "beds". Gold and heavy minerals and metals are forced to the walls of the chambers where they are trapped. As the slurry continuously enters the Centrifuge, the heavier particles displace the lighter particles. At startup, material starts collecting in the first set of chambers. When the first chambers are full, the material es to the second chamber, and so on until the Centrifuge is full. Under continuous run throughout the day, the heavy particles are displacing the lighter particles. At the end of the process day, the heavy concentrate is cleaned out by simply decreasing the speed and flushing the concentrate into a receiver. In most cases with typical alluvial and hard rock ores, a properly sized Centrifuge will give you a full day’s production before it requires flushing. VERSATILITY The Low-G Horizontal Centrifuge is an excellent batch concentrator for primary recovery at volumes from 15-40 tons / hour. Very economical for high volumes of typical alluvial or milled hard-rock ores - Adaptable to any existing classifying circuit - Multiple units can be connected in simultaneous feed for higher volume throughput - Performs well with turbid water, great for recycle loop applications (ponds). For peak production capacity, we recommend classifying the head ore to ¼” minus.

Mobile Placer Plant (MPP) & Mobile Scrubber Trommel Plant (MSTP) Oro industry manufactures a series of mobile alluvial gold processing plants called MPP & MSTP. Each series plant is built rugged for continued around the clock duty. They come with a variety of production ratings from 10 cubic yd/hr to 100 cubic yd/hr. All series plants are designed & engineered as completely self-contained portable gold processing plants with everything required for production mining. All mobile plants have their own feed hopper, classifier, primary gold concentrator, power system, and water pump, mounted on a trailer ready for work. The reason behind MPP & MSTP processing plants is to offer Oro’s clients affordable turn-key mining equipment for small & medium scale mining. Onsite assembly only requires a few hours and you are mining!

MPP-100

Only top quality parts and materials are used in their construction. Both the MPP & MSTP processing plants have onboard CAT powered hydraulic systems, with proven reliable dependability. In the initial deg & engineering of every plant, all moving parts are considered and chosen for their interchangeability and easy replacement in virtually every country worldwide. Because, Oro builds all components for each series plant, spare plant parts are easily obtainable. Mining is tough on equipment and the MPP & MSTP plants are made to handle it, for years and years of dependable duty. All considerations have been made; so you won’t need to buy anything else. Moreover, the plants are specially designed to fit into standard sea containers for easy shipping worldwide.

MSTP-15

Unique in the industry is our line of innovative Mobile Placer Ore Processing Plants. These plants are versatile and economical for alluvial mining projects. Well suited for production and exploration - stationary or mobile applications - very compact and portable. Capacities range from 25-100 cubic meters / hour with continuous feed from either a backhoe or excavator working alongside and feeding ore direct into the plant’s hopper. Our typical design uses a vibrating, wet hopper that flows onto the vibrating screen deck classifier which gravity feeds into the Low-G Horizontal Centrifuge for primary recovery. At the end of the process day, the primary concentrate can then be processed with the Helix Spiral for final concentrating. A feed hopper wash plant, and ore classifier, with primary and secondary concentration comprises a complete system. These plants are built on a towable trailer frame and include onboard power, water pump and electric/hydraulic drive. They are completely self-contained. Their mobility is specially suited to move up and down the alluvial plane, moving the plant to the ore instead of excavating and hauling ore to a stationary plant. Less machinery dedicated to excavate and haul ore means less capital investment and lower mine operation costs. The plant can shift position “on the fly” taking only 15-20 minutes to reposition the plant using the 4 leveling jacks. These mobile plants are great for exploration programs and/or production, and perfect for fluctuating high and low water conditions due to daily or seasonal rains. Site reclamation is more economical, head-ore tailings go right back in the digging trenches during or shortly after the process day instead of mounting up at multiple excavation sites. These plants are virtually "plug and play", minimal assembly required and can be shipped overseas in a standard sea container.

PLACER

PLANT

These series plants are designed specifically for traditional placer type deposits. Placer deposits are made up of mainly sand, gravel & stone found in river channel ways. The MPP plants are a smaller, lighter plant and are very easy to move around the mine site. The MPP ability to process their rated head ore production with a small foot print is second to none. Their reliable and proven design makes it easy to mine in most all placer situations. The MPP series plants have little scrubbing action for clay ore’s. With a clay ore content exceeding 30%, the MPP series is not recommended for use. MOBILE SCRUBBER TROMMEL PLANT (MSTP) These series plants are designed for heavy clay alluvial ore deposits. Alluvial deposits generally have a mixture of sand, gravel & stone, with much higher clay content. These deposits are found more in valleys, mountain bases or spread over sedimentary plains. Clay encapsulates small gold particles making it un-recoverable; to recover these particles the clay must be liquefied. The MSTP is designed for these type alluvial deposits and has the ability to scrub and liquefy the clay. The MSTP are the most versatile alluvial plants and works on all alluvial type ore deposits. They’re larger & heaver then the MPP and a little more cumbersome to move around the mine site. But, the benefits of being able to process any alluvial ore, makes the MSTP the most efficient mobile alluvial process plant available.
