Gold Extraction & Recovery Processes
The process is characterized for its economic cost against the agitated leaching process when the ore deposit has a low gold content. Typically the process can process ores whose gold content is 0.8-1.1 g/t. The leaching solution is spread at the top of the pile and the pregnant solution will have to percolate through the pile. The design considers special drainage pads for pregnant liquid

More ore bodies have been found where the gold is not amenable to simple cyanidation alone. In the simplest of terms, these are refractory ores. The best choice of a processing route to treat a refractory ore will in most cases be site specific, due mainly to the metallurgical and mineralogical characteristics of the ore. The successful
