Bosite's treatment method for arsenic-containing refractory gold ore and leaching process of high-arsenic gold concentrate
Gravity separation is mainly used for placer gold beneficiation. Currently, the commonly used gravity separation equipment in my country's placer gold production includes: shaker, chute and jig. In recent years, centrifugal mineral processing equipment has also been widely used in placer gold beneficiation and has achieved good indicators. In order to improve the conditions for placer gold beneficiation operations and improve the ore beneficiation indicators, some scientific research and design units are studying and applying some high-efficiency placer gold beneficiation equipment.
The concentration ratio of placer gold ore separation by shaking table is high, but the production capacity is low, so it cannot be used as roughing equipment and is mainly used for concentrate operations. In industrial production, if the operating conditions can be well controlled, ideal selection indicators can be obtained, and the gold recovery rate can reach more than %.
Many placer gold mines in my country generally use large fixed chutes for rough selection, and their coarse concentrates can be selected using gold pans alone or small fixed chutes and gold pans. The fixed chute has a simple structure, does not require power, has a large processing capacity, has a wide particle size classification, a large enrichment ratio, is easy to manufacture, and is very convenient to use and maintain. However, cleaning is highly labor-intensive and has poor effect on fine particle separation. It is used as a roughing equipment for small-scale production of natural gold with large particle size.
Jig is one of the main equipment for sorting gold ore. It also has a good sorting effect on fine-grained gold. The gold recovery rate can reach % when sorting placer gold ore. If the sorting conditions of the jig can be better controlled, higher sorting indicators can be obtained, but the concentrate yield of the jig is relatively large and the concentrate operation needs to be strengthened.
