— Fig 2 shows the P 80 of different mineral species in an ore for a major copper operation These values vary significantly with the P 80 of total solids sulfide minerals iron minerals copper minerals and molybdenum are ∼ 200 105 125 94 and 85 respectively Flotation optimization of complex ores often requires a better understanding
— The term reducing power as used in fire assaying is defined as the amount of lead that 1 g of the ore will produce when fused with an excess of litharge For example if we use g of ore and obtain a lead button weighing g the reducing power of the ore is / =
