Gold refinement needs superior crushing equipment

Gravity concentration has been historically the most important way of extracting the native metal using pans or washing tables However froth flotation processes may also be used to concentrate the gold In some cases particularly when the gold is present in the ore as discrete coarse particles a gravity concentrate can be directly smelted to form gold bars In other cases particularly when the gold is present in the ore as fine particles or is not sufficiently liberated from the host rock the concentrates are treated with cyanide salts a process known as cyanidation leaching followed by recovery from the leach solution Recovery from solution typically involves adsorption on activated carbon followed by solution concentration or stripping and or electrowinning.carbon fabricSometimes gold is present as a minor constituent in a base metal (eg copper) concentrate and is recovered as a by-product during production of the base metal For example it can be recovered in the anode slime during the electrorefining process “Gold extraction” or recovery from its ores may require a combination of comminution mineral processing processes to be performed on the ore at a placer mine in Dutch Flat California sometime between 1857 and 1870Gold 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 in the present day are the practice of artisan miners Hydraulic mining was used widely in the Californian gold rush and involved breaking down alluvial deposits with high-pressure jets of water Hard rock ores form the basis of the majority of commercial gold recovery operations today and are mined using open pit or sub-surface mining techniques.The Gold Washing Machine is made up of cutter suction processing equipment and sluice type gold processing equipment,garage equipments compound type gold processing sluice is the most advanced and large production grain selection equipment in the world. Complete upland alluvial gold extraction equipment are introduced; This set of equipment is one of our leading products with many years of production history,tyre changer exported to west Africa, central Africa,Chefs Kitchen Knives Indonesia,carbon sheets Philippines, Nepal, north Korea, Canada and other countries and the major domestic mines.
