Gold extraction - Wikipedia

03/04/2005  Gold extraction refers to the processes required to extract gold from its ores. This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore. 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

Flotation process are widely used for improving the sulfide type gold ore grade. The ore pulp slurry is pumped to flotation cells for extracting. The flotation cells are divided into several parts: roughing, concentration and scavenging (the exact numbers of stages for each part should be decided by test work to reach the best recovery), and with the use of frothing agent and collecting agent, the gold

Gold Extraction Recovery Processes

Heap leaching can be considered as a percolation process on ore piles. The process is characterized for its economic cost against the agitated leaching process when the ore deposit has a low gold content. Typically the process can process ores whose gold content is 0.8-1.1 g/t. The leaching solution is spread at the top of the pile and the pregnant solution will have to percolate through the pile. The design

Comminution is the process where ore particles are liberated from gangue material through progressive size reduction in the form of crushing, grinding, cutting or vibrating. The costs associated with power supply, grinding media, and liners used in comminution circuits almost always represent the single largest cost in gold extraction processes (Mosher, 2005). Thus, the efficiency of the ...
