Lime is added to the mill feed to adjust pH. The ball mill is a 250 kW Marcy-type ball mill that is 8 ft in diameter and 13 ft long. The ball mill discharge is pumped to a hydro-cyclone where cyclone underflow reports back to the mill for additional grinding and cyclone overflow is conveyed via gravity to the rougher flotation cells.

For this reason adding cyclones are used however once a cyclone is added it is difficult to shed circulating load and take it offline without effort. If the pressure goes too high before a cyclone is added the cyclones will rope forcing coarse material out the overflow (grit) relieving the circulating load.
