2016-9-12  tract gold. In a modern gold processing plant, the recovery can be up to 98% with the aid of the latest concentration and smelting techniques. A successful gold recovery strategy re-lies on a fundamental understanding of the ore mineralogy and its chemical/physical behaviors under various leach, flotation, and oxidation conditions. An overview

Establishing thE ProcEss MinEralogy of gold orEs

gold orEs and MinErals gold orE tyPEs Gold ores are commonly classified by the metallurgist into two major categories: free-milling and refractory ores. Typically, free-milling ores are defined as those where over 90% of gold can be recovered by conventional cyanide leaching. Refractory ores are defined as those that give low gold recoveries or

Processing of refractory gold ores ScienceDirect

1991-1-1  More and more ore bodies have been found where the gold is not amenable to simple cyanidation, and low recoveries have been indicated from metallurgical testwork. In 1029 1030 K.S. FRASER et al. the simplest of terms, a refractory ore is one where gold recovery by cyanidation alone is well below normally accepted levels.

Processing of refractory gold ores ScienceDirect

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 bodies. Reasons for ores being refractory will be highlighted.
