OverviewConcentrationTypes of oreGold refining and partingHistorySee alsoWhile the romantic picture of gold mining focuses on nuggets, the reality is that gold is typically recovered from ores containing >10 ppm of the metal. Thus, the main challenge is concentrating this trace amount. The principal technology involves the leaching of gold from the ore by treatment with a solution of cyanide. Thus, the typical first step is comminution to expose the gold to the extracting solution.

Gold Extraction & Recovery Processes Mineral Processing
29/2/2016· Flotation is one of the most important gold recovery processes and its main restriction is to recover coarse gold particles ranging from 400 to 250 µm. This process recovers fine particles of free gold, gold associated in any form with sulphides, and native gold present in polymetallic deposits with certain degree of oxidation.

Gold Processing Plant Multotec
Mined gold-bearing ore containing gold and silver is extracted and purified through a processing plant. In this gold recovery plant, the precious metals are extracted from the ore through a series of steps including: crushing and grinding; addition of process water (forming a slurry); cyanide leaching; floatation and vortex separation (cyclones).

Gold extraction Wikipedia
Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold panning and sluicing, resulting in direct recovery of small gold nuggets and flakes. Placer mining techniques since the mid to late 20th century have generally only been the practice of artisan miners.

Cyanide-free gold recovery CSIRO
The infrastructure for a processing plant that uses cyanidation typically costs $30 million, and is therefore, a barrier to entry for gold miners with smaller deposits that do not fit into the large-scale economies of gold production. Gold recovery by cyanidation is also of environmental and safety concern as it relies on the use of toxic cyanide.
