Sulphide Gold Ore Treatment by Leaching and Flotation Process

Problem with gold recovery from sulphide ore: How may a mill get the maximum recovery of gold from a sulphide ore, at the least capital cost and at the same time obtain the highest net return. This latter point is most important. In many cases a gold mill using an all-cyanide flowsheet with fine grinding of all the ore will report very low gold content in the tailings particularly on an

The cheapest but slowest technique is heap leaching. It is a process usually applied to low grade gold ore. Basically the ore is piled to a given height on an inclined impermeable surface, a so called leach pad. A sprinkler system provides a continuous spray of alkaline cyanide solution that percolates through the ore dissolving the gold.

What Are Commonly Used Gold Recovery Chemicals? CNFREE

The heap leaching method is mainly suitable for low-grade gold ore recovery, with the average grade of gold ore is 0.8-1.5g/t. Heap leaching gold recovery process is to first crush the ore to certain particle size (-15mm) and then convey it to the storage hopper, adding gold ore, lime and binder according to the specified amount, mixing them

4 Factors Influence the Effect of Heap Leaching Method

Generally, the smaller the ore size, the shorter the leaching time and the higher the leaching rate. In practice, the ore particles that have been crushed to 5~20 mm are sent to heap leached. If the content of ore fines -200 mesh exceeds 35%, the conventional heap leaching method will cause the surface of the ore heap to form a groove flow

Processing of chalcopyrite ore by heap leaching and flotation

Nov 10, 2017· 1. Introduction. Heap leaching of chalcopyrite (CuFeS 2) yields much lower copper recoveries that those obtained from leaching chalcocite (Cu 2 S) ores. The low recoveries are thought to be caused by the deposition of reaction products on the chalcopyrite surfaces, forming a passivating layer that hinders dissolution of the mineral (Watling, 2013).The nature of the passivating layer is still
