Gold-Copper Ores
A somewhat similar experience occurred at the Mt Gibson gold plant, which was designed to process laterite ore, which overlaid deeper mixed oxide–sulfide ore. The ore contained about 500 g/t cyanide-soluble copper, some of which was associated with sulfide mineralization and which occurred within highly weathered clay minerals.

Placer gold refers to the gold formed by the rock gold in the mountain washed by the river and separated from the quartz vein. Because this kind of gold is as fine as sand, it is called placer gold. Gold mining is divided into rock cave digging and panning in rivers and streams containing gold. For example, gold taken from mines is called gold ...
