Refractory Gold Mining SGS

SGS has developed a series of testing and mineralogy assessment protocols that allow us to determine the character of refractory gold and the mass balance between refractory and free-milling gold. Once the deportment or textural associations of the gold is determined and the mass balance known flowsheet options are developed.
