Gold-PM Conference

2017-6-28  More ore bodies have been found where the gold is not amenable to simple cyanidation alone. In the simplest of terms, these are refractory ores. The best choice of a processing route to treat a refractory ore will in most cases be site specific, due mainly to the metallurgical and mineralogical characteristics of the ore.

2021-9-23  STEINERT ore sorting solutions complement and reduce the burden on the downstream stages of conventional processing. This greatly reduces the overall costs for process materials such as water and leaching agent, while the material recovery facility can be made smaller, because the waste rock is no longer processed.

Carbon in leaching process also be called CIL plant. In this production line, use cyanide leading and carbon absorbing technology to get gold. CIL plant consists of following steps: 1 The ore is first reduced in size (typically 80% passing 200mesh ) to ensure that all nonrefractory gold is readily accessible for cyanide.
