The process mineralogy of gold: The classification of ore

The principal gold minerals that affect the processing of gold ores are native gold, electrum, Au-Ag tellurides, aurostibite, maldonite, and auricupride. In addition, submicroscopic (solid solution) gold, principally in arsenopyrite and pyrite, is also important.

Establishing thE ProcEss MinEralogy of gold orEs

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 give acceptable gold recoveries only with the use of significantly more reagents or more complex pre

Mineral Processing and Ore Dressing

2016-6-2  Mineral Processing and Ore Dressing. Before the event of ore dressing, crude ores were shipped directly to the smelters, or the refineries, with the shipper paying the freight and treatment charges. These charges varied with the type of ore and the distance from the smelter. In all cases they were many times our modem milling costs.

How to Process Gold Ores by Heap Leaching & Carbon

2021-2-18  Generally, silver is also dissolved by the cyanide solution and follows the gold through the process sequence. Iron sulfide minerals, which are common constituents of gold ores, are oxidized to some extent during the cyanide leach, thus resulting in the formation of acid. These acids are neutralized by the lime used in the cyanide leach sequence.
