Process Description of Milling in Water A copper processing plant that utilises a hydrometallu rgical process generates an acidic solution called high-grade raffinate containing 18 g/L H2SO4 and a low-grade raffinate containing 8.9 g/L H2SO4. H2SO4 is used for the copper leaching process; hence, recirculation of these two raffinate …

A SAG mill, or semi-autogenous grinding mill, is a type of machine used in mining and mineral processing operations. It uses the crushing and grinding action of rocks to reduce materials such as copper ore into smaller pieces for further processing. Unlike traditional mills that rely on steel balls or other media to break down materials, SAG ...
