Slurry from the grinding circuit, at approximately 35% solids and 80—85% passing 135 mm is pumped to three thickeners. Thickener underflow, at approximately 54% w/w solids, is pumped to a train of four acidulation tanks. Sulfuric acid is added to the slurry to destroy sufficient carbonate prior to entering the autoclave circuit. Process air is also injected into the acidulation tanks to aid ...
