The design of mining and processing plants is a complex task, which is solved by multidisciplinary teams of engineers, geologists, architects, economists, marketers and other specialists. Compounds of gold, silver, …
Small gold processing plant for river dirt gold with clay. This mobile gold washing plant normally works together with a sluice box, gold centrifugal concentrator, and shaking table to form a complete concentration plant. It is an excellent plant for small-scale miners. Small Scale Hard Rock Gold Process Plant 3 TPH Rock Gold Process Plant
At current gold prices this is worth about US$600. Both smelter treatment charges and oxidation or bio-leach costs are at least $200/t of concentrate and payables/recovery in …

Capacity: 1-20 TPH Process Material: Gold, diamonds, gemstones, and other heavy materials. Introduction: This mobile jig concentrator is very popular in small-scale gold, diamond, and coltan processing plants. The trommel screen sieves out big waste stone firstly, and then the under-sieve material goes to the jig concentrator for gravity separation.
