Nov 01, 2013 Ultra fine grinding of the plant tailings of a refractory silver ore was studied using a laboratory type vertical stirred media mill. Preliminary tests confirmed that ultra fine grinding substantially improves the extraction of silver from the tailings in cyanide leaching (i.e. 36% Ag extraction rate from the as-received tailings with d 80 of 100 μm, c.f. 84% extraction rate after ultra fine

Get PriceOre Grinding Mills are used for the fine grinding as the last step in the reduction of an ore prior to concentration (gravity or flotation) or cyanidation.Practice varies, depending upon the type of ore and the amount of reduction required. In addition, some of the older properties continue with methods that perhaps are not considered the best in light of recent improvements but that cannot be
Get PriceI found a silver vein in the oases on the barrens, hard to get to until you're lvl 15 or so, but well worth it, usually a tin vein in each pool, and ive seen a silver pop up as well. If there are veins there, mine them, even if you dont need that ore, theres a high drop rate for jewels here too

Get PriceOre processing technologies extract economically valuable minerals and metals. They include the collection of naturally occurring metals and minerals (e.g., placer gold or lode silver), crushing and grinding ores, mechanical concentration of ores containing metals and minerals, and breaking down the ores with chemical, heat, and electrical
Get PriceABSTRACT In this study, ultra fine grinding of a refractory silver ore tailings was studied. A laboratory scale pin−type vertical stirred mill and ceramic beads were employed for the grinding tests
Get PriceElectrowinning is the recovery of metals, such as gold and silver, from solution by passing a current through the solution. Electrons from the current chemically reduce the gold and/or silver ions, to form a solid metal compound on the cathode. ... Traditionally, grinding ore to a small particle size was thought to maximise recoveries. However
