Lime is added to the ball mill for alkalinity control together with mill cyanide solution for dilution. About 75% of the recoverable values are usually dissolved in the grinding circuit. The overflow or pregnant solution from the primary thickener goes to the bag-type zinc dust precipitation unit for recovery of the values as a precipitate.
For the mining industry, our semi-autogenous (SAG) grinding mill uses a minimal ball charge in the range of 6-15 percent. It is primarily used in the gold, copper and platinum industries as well as in the lead, zinc, silver, and nickel industries. Autogenous (AG) grinding mills involve no grinding media as the ore itself acts as the grinding media.
