The ore is then delivered to the crusher or the appropriate stockpile depending on the daily blending requirements Kumtor has an active and dynamic blending program in close contact with the mill that adjusts the ore blend as required to maximize the gold recovery MILLING
Gold extraction refers to the processes required to extract gold from its orThis 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 .
The ore is ground into a fine powder by large rotating mills The two types used in the Mission South Mill are called SAG (semi-autogenous grinding) mills and ball mills SAG mills use larger pieces of ore to break up the smaller pieces (autogenous — does it by itself) The larger pieces break down as well
Removing the gold-bearing rock from the ground is just the first step To isolate pure gold, mining companies use a complex extraction process The first step in this process is breaking down large chunks of rock into smaller piec At a mill, large machines known as crushers reduce the ore to .
Cost Effective Ore Milling - Mt Baker Mining and Metals

A slurry of ground ore, water and a weak cyanide solution is fed into large steel leach tanks where the gold and silver are dissolved Following this leaching process the slurry passes through six adsorption tanks containing carbon granules which adsorb the gold and silver This process removes 93% of the gold and 70% of the silver
Ore is stockpiled (1) at the processing plant, and the process begins by feeding the ore into a hopper with a loader The ore is conveyed, and lime is added (2) to raise the pH of the ore Following crushing through a jaw crusher (3), the ore is fed into the semi autogenous grinding (SAG) mill (4) along with water and steel balls
Gold is processed by cyanide milling, a chemical procedure that separates 95 to 98 percent of the gold from raw mined ore It is then refined to the gold standard purity, according to Mineweb Heap leaching is a less expensive method of gold extraction, but it is a longer process and it recovers less gold than the cyanide milling process
