The carboninpulp process is used to treat low grade gold andor silver ores The ore is first ground in a ball mill which operates in closed circuit with a cyclone or similar sizing device This is done to produce a feed suitably sized so that subsequent leaching is rapid
The three product solution illustrated above can be somewhat simplified by taking an intermediate tailings sample between the two stages of concentration ie a copper tail zinc feed sample in the previous example Then adding the notations Copper tail zinc feed CT with copper and zinc assays c 5 and z5 Assume mill feed F as Unity 1
Both methods require the resultant molten copper to be further processed to achieve a grade of 999 pure copper During the process the gas given off is converted to sulphuric acid which can be used in the plant or sold off as a byproduct
