There are several major factors that affect gold ore processing. Of which, gold grade, mineralogy and metallurgy are the three major ones. Technically, gold is commonly extracted from various ores using gravity, flotation, cyanidation or a combination of these processes. For refractory gold ore processing, pre-treatment technologies such as fine …
The gold mining process is complex and lengthy — Gold exploration companies perform numerous tests to identify the size and quality of the ore body and a plan on how to extract the ore as safely, sustainably, and economically as possible before they can start mining gold.
The technology for determining whether or not a gold ore is amenable to percolation leaching with weak cyanide solutions is well established. Initially, bottle cyanidation tests are conducted on 200- to 500-gram charges of ground ore to determine the degree of gold extraction and reagent consumption.
Different types of gold ore have different physical and chemical properties, which affect the mining, processing, and refining methods used to extract the gold. In …

Thiosulfate (S 2 O 3 2−)-based gold extraction—an environment-friendly alternative to cyanide-based gold extraction—has notable potential for application in industries. However, resolving the detrimental impacts of arsenopyrite on gold ore leaching remains a challenge for various leaching methods.
The method used depends on the type of mineral resource that is mined, its location at or beneath the surface, and whether the resource is worth enough money to justify extracting it. Each mining method also has varying degrees of impact on the surrounding landscape and environment.
Prior to mining, all rocks contained in a mineral deposit must be placed in one of several categories known as ore types. Each ore type describes a different way that the rock will behave in processing. The ore type determines which process stream a particular mined unit will be sent to, sets expectations for process engineers and metallurgists, and …
