Gold recovery by KC from grinding circuit of Bergama CIP plant
Gold grade of the cyclone underflow is determined to be 56.79 g/t. It can be seen from Table 1 that about 67.27 % of total gold content of cyclone underflow material is below 75 microns showing that the most of the gold particles in the circulating load is in 0/75 micron fraction. The gold grade of this size fraction is about 244.48 g/t.Gold recovery efficiency from operating heap leaches is typically ∼70%, although it can range from 50% to 90%. Silver recovery efficiency is typically ∼55%. Most gold heap leaches apply cyanide within a range of 200–600 mg/L NaCN. Silver-bearing ores should usually be leached with a cyanide level of 600–1000 mg/L NaCN.Heap Leaching of Gold and Silver Ores ScienceDirect

The leaching rate of copper reaches 91.54% and more than 99.8% of gold and silver are enriched in the slag for further recovery when the alkaline washed waste acid residues are subjected to theThe capital cost of the plant was ∼$5 million and the operating costs were about $1.00/kg of NaCN recovered. Not only was this cost lower than the cost of new cyanide delivered to the plant ($1.30/kg NaCN), but the cost of cyanide destruction (reported to be in the range $0.50–1.00/kg NaCN) was avoided.Cyanide Recovery ScienceDirect
