A zinc ore of specific gravity 2.80 and assaying 3.5 zn is milled in a ball mill and pumped into a conditioning tank at the rate

Transcribed image text: Question2 (a) A zinc ore of specific gravity 2.80, and assaying 3.5% Zn is milled in a ball mill and pumped into a conditioning tank at the rate of 85 tonnes/hour, where it is conditioned with reagents for 5 minutes. The conditioned pulp containing 45% solids by weight is then treated by froth flotation to produce a concentrate of 25% Zn and tailings of 0.05% Zn

    The mine produces two types of ore; MC (+MCZ) copper ore and MZ zinc ore. Production of tin ore (RT) ceased in the early part of 2006 with the processing plant subsequently being converted to treat zinc. Production in 2006 totalled 1.95Mt copper ore and 0.15Mt zinc ore. Production for 2007 is budgeted to be 2.0Mt copper ore and 0.4Mt zinc ore
