Most cyanide leaching is carried out at a alkaline pH of between 10 and 11 depending upon lab testing of individual ores and the optimum leaching/chemical use rates The cyanide solution strength is also important in leaching gold with the typical range of solution being in the % % NaCN The gold particle size has a tremendous effect
The amount of tailings generated is dependent on the ore grade proportion of valuable minerals in the ore For example if the cut off grade in the ore is 1 % Copper 99 percent of the total ore would be deposited as tailings Iron ores generally have higher grades than sulfide or gold ores often going over 50 per cent or more
