A Filtration Model for Optimization of a Gold Extraction Plant

African gold mining industry at present consists of mill­ ing the ore down to a predetermined fineness and dissolv­ ing the gold from the ground aggregate with a cyanide solution in 'Browns' tanks. The slurry from the Browns tanks, consisting of solid particles (i.e. rock) and dissolved gold solution (called the pregnant solution), is routed to the filter plant where the solid and liquid
