Gold Ore - an overview ScienceDirect Topics

In this process, three main reactions occur: the litharge is reduced to lead, which collects almost all of the gold, silver, and platinum group metals to form lead bullion, while the pyrites decompose to form ferrous sulfide and sulfur, which converts copper present into copper sulfide or matte, and the fluxes combine with the nonmetallic components of the charge to form slag.

9 Step Process for Discovering, Mining Refining Gold

2012-1-23  Once ore is extracted, processing it into pure gold must be done. Ore is first crushed and then undergoes various processes depending on the nature of associated minerals. Processing low-grade ore is relatively simple while higher grades require more extensive processing.

The process mineralogy of gold: The classification of

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.

Heap Mining Efficiently Leaches Lower Grade Gold

There are other chemical processes used in heap leaching, but the cyanide process is most common. This process can take several weeks or months to extract the gold. And the leaching time can also increase if the heap leach pad becomes too compacted. The cyanide must come in contact with the gold particles and sometimes it penetrates very slowly.
