The amount of iron oxide copper gold ore is about 10 million to 4 billion tons. IOCG ore contains copper with a grade of 0.2% to 5% and gold with a content of 0.1 to 1.41 grams per ton. Iron oxide copper gold ore tends to be conical on the edge of granite, or appears as long banded breccia or massive iron oxide ore in faults or shears.

ren in gold leaching, is refortified with the lixiviant chemicals and pumped to the top of the heap. Heap leaching is often broken into two principle distinc-tions, run-of-mine or ROM dump leaching and crushed ore heap leaching. Dump leaching consists of truck end-dumping of ore broken only by the drilling and blasting of mining activ
To those of us in the gold industry, the question “What is heap leaching?” seems to have an obvious answer. In the simplistic sense, heap leaching involves stacking of metal-bearing ore into a heap on an impermeable pad, irrigating the ore for an extended period of time (weeks, months, or years) with a chemical solution to dissolve the sought-after metals, and collecting the leachant

Leaching and recovery of gold from mildly refractory ore in glycine media was investigated. Temperature and pH have a substantial role in gold dissolution. 90% of gold extracted into the glycine solution after 24 h of leaching. 100% gold recovery from solution could be achieved by carbon adsorption within 4 h.
