CHANGCHUN GOLD RESEARCH INSTITUTE

STL series of Water Jacket Gold-selecting Machine

   STL Model water jacket gold-selecting machine is a kind of centrifugal ore-dressing equipment. Instead of amalgamating operation, it suitable for the recovery of the free gold in the ore of placer gold, gangue gold and multi-metals, it can also recover the free gold from gold-bearing copper concentrate and gold concentrate of flotation.

   Our institute began to develop this equipment in 1985 and has turned out four types of it. Ore tests have shown that the placer gold can be up to above 99%, when 65% of grinding size is passing 0.074mm, the recovery of free gold in the ore of gangue gold can be up to above 98%, 97% of recovery can be obtained from 0.04mm of free gold. Ore-discharging period is from 1hour to 4hours, the ratio of concentration can be up to 1000 times.
