"Pay" gravel is excavated from the front face of the pond and processed through the floating plant, with the gold trapped in the onboard sluice box and tailings stacked behind the plant, steadily filling in the back of the pond as the operation moves forward. This type of gold mining is characterized by its low cost, as each rock is moved only ...
Starting in May 1999, the tailings were pumped from the Meda pond to the Aurul S.A. processing plant, where sodium cyanide was added for recovery of residual gold. After gold and silver extraction, the remaining tailings contained total cyanide concentrations of 400 mg/Litre, with free cyanide concentrations of 120 mg/Litre.
heap leaching, which has a relatively low level of energy consumption, is for example successfully used for the beneficiation of certain types of gold ores in Turkey . It contributes to the substantial development of a sustainable gold mining sector in that country and has the

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.
The pregnant leach pond contains copper ions that give it the blue colour of copper sulfate. The liquid is continually pumped to the SX-EW plant. 3. Copper sulfate solution is collected in the pregnant leach pond then pumped to the solvent extraction plant. The solvent extraction .
The excess of water in the process can be treated in the Reverse Osmosis Plants (RO). Processing Gold Ore by Milling by Cyanidation Oxide, transitional and deep transitional ores (high grades) will be processed in the Gold Mill plant according to their content of CuCN, %SS, gold and silver.
Paste tailings is a modification to the conventional methods of disposal of tailings (pond storage). Conventional tailings slurries are composed of a low percent of solids and relatively high water content (normally ranging from 20% to 60% solids for most hard rock mining) and when deposited into the tailings pond the solids and liquids separate.
