Gold Separating Machine

 

A gold separating machine removes gold from clay-bound alluvial gravel by washing, scrubbing and size-classifying the feed before it reaches the recovery stage.

Sinolion builds trommel-type units for placer operations that need high throughput without losing fine gold, from 5 t/h mobile skids up to 350 t/h production plants.

 

 

 

In an alluvial operation the raw feed is a mixture of sand, gravel, clay and a very small fraction of gold. A gold separating machine is the first stage that turns that mixture into something a recovery unit can work with.

 

Its job is not to catch gold. Its job is to break down clay, wash out the light material and hand the concentrator a stream that is uniformly sized and free of lumps.

 

Get that first stage right and the sluice, the concentrator and the shaking table all work at their rated efficiency instead of compensating for it.

 

 

 

On a gold separating machine the rotating drum is the core. Feed enters the screen cylinder through a hopper, where a round-bar grizzly with 30 mm bars rejects oversize rock before it reaches the deck.

 

Bar spacing is fixed at order time, and an I-beam grid is available for boulder-heavy loads.

 

As the drum turns, the tumbling load and a spray manifold across the hopper and drum break down soft clay.

 

 

Two woven high-manganese decks then cut the material into size bands in the same pass. A 25 mm inner deck holds back the coarse stone that rolls out through the side chute, while a 6-10 mm outer deck passes the fines that carry the flour gold.

 

Screen segments bolt out individually, so a worn area is swapped in hours without lifting the drum.

 

 

 

The GMTS range covers the practical span of placer operations, from a single-operator claim to a full production pit. Feed acceptance widens from ≤300 mm up to GMTS1225 to ≤400 mm from GMTS1548 upward.

 

Every gold separating machine in the range is started, loaded and inspected on our factory floor before it is crated.

Capacity is the number buyers ask about first, but on a gold separating machine the money is usually lost in three places that never appear on a spec sheet.

 

 

 

 

A gold separating machine relies on the principles of gravity and mechanical screening to separate heavy gold particles from lighter sand, gravel, and clay. For sand gold operations, the primary piece of equipment utilized is the trommel screen.

Raw material is fed into the rotating drum of the trommel screen, where high-pressure water jets break apart clay and wash the aggregate. As the drum rotates, the material is classified by size.

Clay handling. Light clay is broken down by the drum's spray manifold and tumbling load. Heavy, clay-cemented ore sits outside this machine's design envelope - for that feed a rotary scrubber is the correct tool.

 

Screen selection. Aperture is ordered to your mesh spec, because the right opening follows the gold particle size in your ground rather than a catalogue default. The two-deck arrangement lets one machine produce a coarse stream and a fines stream at the same time.

 

 

Slurry routing. On the two-outlet configuration, material under 5 mm is discharged to the gold chute and collected through one sluice, while the 5-30 mm fraction leaves through a second outlet.

 

Nothing drops out of the bottom of the drum, so fine particles are directed to a recovery device instead of to the tailings pile.

 

 

 

A gold separating machine is one station in a line, not a standalone product. Upstream it needs a stable feeder and water; downstream it feeds whatever recovery stage matches your gold size distribution.

 

In our standard module build the line runs feeder, then the washing and sizing drum, then a sluice box 6000 mm long and 1000 mm wide lined with polyethylene recovery carpet for the coarse gold.

 

Behind it a bank of fully continuous centrifugal concentrators works the -6 mm undersize, each unit rated 2-80 t/h. A plant normally carries two to four of them, so one can be serviced while the others keep producing.

 

Concentrate from the sluice and from the concentrator bank is then combined and finished on a 6S shaking table, and the furnace pours the result in 10-15 kg batches into 100 g, 200 g, 500 g and 1000 g moulds.

 

 

 

For a plant as a whole, 90-97% is the honest planning range, and where your figure lands depends on how the gold sits in your ground. On the fine fraction, adding centrifugal concentrators lifts recovery to about 98% in our tests under standard gravity conditions.

 

Which recovery modules you pair with the machine sets that final number, and it is a decision made before the gold separating machine is built rather than after.

 

Treat both figures as planning aids rather than guarantees, and confirm them against a sample test of your own material.

 

That is why ore testing and flowsheet design come before the order and not after: the flowsheet states the expected recovery, and that document defines what gets manufactured.

 

 

 

 

 

Zhengzhou Sinolion Machinery Co., Ltd. is a manufacturer of mobile and stationary trommel screening machines, rock gold plants and gold washing plants, fully built in-house rather than sourced from trading partners.

 

The company also provides repair services and 24/7 spare parts support.

 

Trommel plants have been shipped to customers in Africa, South America, Southeast Asia and the Middle East, and recent alluvial wash plants from the Zhengzhou factory are working in Ghana, Nigeria, Sudan, Indonesia and Russia. Reference contacts are shared on request.

 

 

 

 

 

 

Send the ground type - sandy, clayey or tailings - the capacity you need in tonnes per hour and your site power situation.

 

The reply is a configured flowsheet with a named model and a factory price, not a generic list figure. Our engineers size the gold separating machine and the recovery package together.
