The gold that is left at Haile, after nearly 200 years of mining, is found in the ore body below the ground. During this phase of our operations, we are using open pit mining, which is what it sounds like…we make open pits in the ground and haul the ore out to be processed and the gold removed. Mine pits are being opened to various depths in ...
African gold plant. These figures are not a standard but reflect the nature of the ore and the design basis for a particular situation. The ore is first reduced in size (typically 80% passing 75µm) to ensure that all non-refractory gold is readily accessible for cyanide leaching. There are several variations of comminution circuits used in the ...
