Nov 02, 2018 · The carbon-in-pulp process is used to treat low grade gold and/or 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 ground ore overflowing the sizing device generally runs at 25 to

On the other hand, there are alternatives for processing sulfide ores. The way the Spanish did it, the old “patio” process - is still a possibility for small miners. Actually more recently the big mining companies have come around to adopting a modernized use of this ancient practice, because it's less polluting
