Other Gold Processing Equipment

Apart from the mentioned products there are other gold processing equipment which are manufactured and exported by Star Trace. The following are equipment: Trommel Screen, Vibrating Screen, Screw classifier, Dewatering Screen, Electrowinning, Leaching Process, Gold Refining, Flotation Cell, Sluice Boxes and Gold Pans.

Trommel Drive:

Vibrating trommel screen are used to separate materials into various sizes for further processing, or for end use.

GyratoryDepending on particular need, the material is separated by passing it through a vibrating “screen box” which has a number of different sized screens or meshes, which the material falls through like a sieve, the material falls onto attached conveyors which stock pile the end products.

The end products can then be used in the building and construction industries.

• High screening efficiency
• High capacity and reliability
• Long bearing lifetime
• Easy maintenance

Vibrating Screen

The type universal Vibro Screen is a new generation vibratory screening machine characterized by low profile, efficient protection of support structure from vibrating masses and virtually noiseless operation.

The various versions of these Vibro Screens permit its use for:

• Wet and dry screening
• Coarse and fine separations and are widely used in steel mills
• Mineral beneficiation plants
• Chemical
• Mining food and fertilizer industries
• Coal preparation plants and many others.

The standard range of screens from 300x900mm to 3000x9000mm in single and multi deck configuration.

Screw Classifier

Screw sand washing machine is mainly used for sand processing, electric pole factory, building work site and concrete dam, various sands classifying and dewatering.

The Screw Washer adopts inclination 15°, under the water tub, three weir plates form the sediment pool, the screw head is immersed in this pool, the screw is driven by electric motor through reducer rotating continuously, the fresh water is feeding from porous plate at bottom of sediment pool, this machine have three functions of washing, dewatering, classifying.

Dewatering Screen

Whilst enjoying immense popularity for many years on small horizontal and inclined screens, STAR TRACE is the first company in the India to perfect this simple drive arrangement on large horizontal and inclined screens. This single development has resulted in tremendous advantages as far as reduced maintenance, compactness and simplicity are concerned. Besides the simplicity of the drive, many other features have been incorporated to provide a machine which is specifically designed for heavy duty applications, long life and low operating and maintenance costs at a competitive price. The standard range of screens from 300x900mm to 3000x9000mm in single and multi-deck configuration.

Electrowinning

Electrowinning also called electroextraction, is the electrodeposition of metals from their ores that have been put in solution or liquefied. In electrowinning, a current is passed from an inert anode through a liquid leach solution containing the metal. So that the metal is extracted as it is deposited in an electroplating process onto the cathode. In electrorefining, the anodes consist of unrefined impure metal and as the current passes through the acidic electrolyte.The anodes are corroded into the solution so that the electroplating process deposits refined pure metal onto the cathodes.

Leaching Process

Scrap printed circuit boards were selectively smelted at 1200°C to produce a metallic alloy having three phases. These phases were identified as a lead-rich phase, a low tin content alpha bronze phase and a high tin delta phase. Electrochemical leaching method on this alloy were done in 1 mol/dm3 sulfuric acid or in 2 mol/dm3 hydrochloric acid (adjusted to an ionic strength of 3 mol/dm3). The lead rich phase was more strongly passivated in sulfate media and in this medium the high tin content delta bronze was more resistant to corrosion than the lower tin alpha bronze phase.In chloride medium the lead phase and both bronze phases corroded readily, but with current densities about an order of magnitude lower than in sulfate medium (static conditions) for the bronze phases. The high tin delta bronze phase was found to form a passivating layer in sulfate media. A similar layer was not seen in chloride medium.The leaching method in sulfate medium also showed the existence of an alpha bronze phase of lower tin content in the centres of the alpha phase grains. This phase was quite resistant to leaching in sulfate medium.STAR TRACE offer complete leaching process with highly cost-effective and environmental friendly process.

Gold Refining

Gold is purified by means of a smelting process, which utilizes pressure, high heat and chemicals to accomplish the task. Like any metal that appears naturally in the earth, there are impurities that must be removed. Removing minerals and other impurities allows gold to be used in its purest form.The cathodes are washed down and the gold is collected and then smelted at more than 1000°C. The molten material is poured to make gold bars.The gold is collected and taken to the gold refinery and then on-sold for use in a wide range of products.

Floatation Machine

STAR TRACE designs and manufactures all sizes of flotation cells. Multiple impeller/diffuser configuration can be used to either enhance or restrain mixing depending upon the nature of the ore being treated. The robust design allows the structure to be self-supporting and thus fewer supporting beams are requires for installation.

Metallurgically the hydrodynamic shape eliminates short-circuiting and prevents sanding. Specially profiled impellers and diffusers enhance efficient pumping of the slurry.

Excellent dispersion of the external air feed and homogeneous mixing of the air and slurry all contribute to superior recoveries and grades being obtained. The impellers and diffusers are moulded rubber or polyurethane coated for abrasion resistance.

Sluice Boxes & Pans

Our Star Trace Sluice Boxes are designed to adapt to our new “Marvel Mat” that is placed under the classifier screen for superior recovery. A lighter design for portability as well as rolled top edges for superior strength on 2.5” and up models only. Included is a large classifying screen that covers over half of the riffle section, miners moss for fine gold recovery and wire mesh screen over ribbed carpet to give you simply the best fine gold recovery one could expect with a sluice box.

The 3 Stage Sluice Box is simply the lightest, most compact sluice box you can find for superior fine gold recovery. The secret is in our 3 Stage Sluice System that enables us to say that our sluice can out perform any double or triple sluice on the market.

This sluice box features heavy duty latches, rolled top edges that provide greater strength and safety, a longer rubber damper for more even distribution and an adjustable flow metering plate for the lower sluice.

• Pan three times as fast as a conventional gold pan.
• Has three surfaces that perform specialized tasks.
• The coarse riffled area is used to "rough out" the majority of the material.
• The textured area is used to pan any remaining black sands.
