Gold Extraction Methods From Three Types of Ore
Gold has always been prized and coveted from ancient civilizations to modern society. While the quest for this precious metal may have changed over time, one thing has remained constant – the need for efficient methods of extracting gold from ore. Extracting gold from ore is a complex process that requires precision and expertise.

However, there is great disagreement about the metallogenic factors. For Shuidong gold deposit, the ore-forming fluid may come from deep mantle [9-11] or basin construction water [12], or from mixed sources [9, 13]; the ore-forming materials of the deposit may originate from Emeishan basalt [14], or mixed sources [9, 13].

The process mineralogy of gold: The classification of ore types
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. The main causes of refractory gold ores are submicroscopic gold, the Au-Ag tellurides, and very fine-grained gold (<10 µm) locked ...

Types of Ore Bodies
Because of the laxity in type differentiation which has prevailed among miners and writers, the same geologists who have framed definitions of ore, have also defined the various types of ore bodies. The definitions, having been accepted by the leading mining geologists and engineers of the present day, it is well for us to fall into line and to agree with the authorities in such matters.

Heap Leaching of Gold and Silver Ores
Where uncrushed ore (run-of-mine (ROM) ore) is placed on the leach pad, ore may be blasted very heavily in order to reduce rock size and improve gold recovery. In high-rainfall environments when processing clay-rich material, it is very important to practice a mining routine that minimizes the amount of rainfall absorbed by the ore.

6. Epithermal gold ore. Epithermal gold ore is a type of gold ore that is formed near the surface of the Earth by the action of hot fluids. It is often associated with volcanic rocks or geothermal systems. The processing of epithermal gold ore involves crushing the ore to a fine powder, which is then mixed with water to form a slurry.
