offer or use the processes A refractory gold ore is gold-containing ore that is resistant to recovery by direct cyanidation and carbon adsorption process More specifically, it is an ore that has a gold recovery rate of less than 80% when direct cyanidation is applied to it...
As free-milling oxide deposits are depleted on a world-wide scale, the mining companies capable of efficiently mining and processing both low- and high-grade refractory sulfide deposits will become industry leaders This chapter addresses a new process for the biooxidation of refractory gold ores developed by GeoBiotics, Inc...
Plating With Refractory and Other Exotic Metals Electroplating is a process used to provide a protective coating onto the surface of an underlying metal, which is referred to as a substrate, via a technique known as electrodeposition...
Refractory gold ores present a number of problems to the gold producer Much has been written about the suitability of particular pretreatment processes for specific gold or We at Hazen Research have had the opportunity to participate in the development and application of a number of gold ore processes and to review others'...
Gold-containing ores having an excessive refractory content of sulfidic and carbonaceous matter are made amenable by the invented process to facilitate gold recovery by conventional processes such as carbon-in-leach adsorption...
More ore bodies have been found where the gold is not amenable to simple cyanidation alone, and low recoveries have resulted from metallurgical testwork In the simplest of terms these are refractory ore bodi Reasons for ores being refractory will be highlighted...
Using similar processing units as the Kell platinum process, KellGold can recover gold, silver, base metals and rare metals from a range of refractory sulphide concentrates that respond poorly to conventional cyanide recovery methods...
