gold leaching adsorption plant

Gold Project Flowsheet Design | SRK Consulting

Ores in which gold is locked with sulfides are processed by combining flotation with other methods. To recover gold from sulfide concentrates, roasting or oxidation can be performed first, followed by cyanide leaching. Direct cyanidation of flotation concentrate can often encounter problems.

Gold processing 101 - Mining Magazine

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 the 90% range, so a minimum GSR for effective downstream processing is around 0.5. Clearly this is a function of gold price, but in the current gold price and cost ...

Heap leaching a stack of gold - MiningFeeds

Heap leaching requires less aggressive techniques: a chemical solution is simply sprayed on heap ore. As the solution percolates through the heaped ore, it dissolves the gold. The solution is then collected and treated further by adsorption. The heap leach stack must be porous enough to allow the solution to drip or to drain through the stack.
