Bosite low-grade gold-containing sulfur concentrate thiourea method for gold leaching, leaching refractory gold and silver ore process
The content of gold in placer gold mines is extremely low, and generally needs to be enriched and purified before proceeding to the next step. Many customers are unfamiliar with the methods and equipment for purifying alluvial gold. Today, Bosite Machinery will tell you about the methods and equipment for purifying alluvial gold. We hope it will be helpful to our customers.
The content of gold in sand is extremely low, and the content of some placer gold deposits is even lower than //, so it needs to be enriched and purified to reach the level of smelting. Since the specific gravity of gold is large, much greater than the specific gravity of sand, Therefore, it is very feasible to use gravity separation to purify alluvial gold. The practical results also prove this point of view. Gravity separation is the most effective and popular method to separate alluvial gold deposits.
Gravity separation method is a gravity separation method. It is a mineral separation method that separates minerals according to different specific gravity. The primary issue when using gravity separation method is the selection of gravity separation equipment. The gravity separation method has a great effect on mineral separation. It depends on the selection of gravity separation equipment, so choosing the correct gravity separation equipment is also the primary condition for improving mineral processing indicators.
Gravity separation equipment mainly includes jig, shaker, spiral chute, spiral concentrator, centrifugal concentrator, etc. The more commonly used alluvial gold gravity separation equipment is mainly jig, shaker and spiral chute. Among them, the jig can be used as rough and fine selection equipment for placer gold mines. It can perform both rough and fine selection of alluvial gold, and the enrichment ratio and recovery rate can both meet the mineral processing indicators. However, the shaking table has a small processing capacity and a large area. There are almost no examples of using a shaking table alone to process placer gold ore in alluvial gold concentrators. The spiral chute is also a roughing equipment for placer gold mines. It has a large processing capacity, a low recovery rate, and a low enrichment ratio. It is used on some small gold mining ships for roughing alluvial gold.
The jig machine has the characteristics of large processing capacity and high recovery rate. The mineral processing process is also relatively simple. It only needs simple screening to enter the jig for separation. A trapezoidal jig machine is used. The recovery rate of sorting placer gold ore can reach more than %. The placer gold coarse concentrate, that is, heavy sand, after being sorted by the jig, can be directly purified by mercury amalgamation or shaker gravity separation, both of which can achieve good purification effects. At present, large gold mining ships use cylindrical screen jigs. The mechanical technological process is used to select placer gold ore, and all mineral processing indicators are relatively high.
