Determining Stripping Ratio

Determine the BESR in mining and processing a 0.60% copper ore deposit if the selling price of copper in concentrate is $1.63/kg and the overall unit costs are $6.80/ton and the cost of handling unit weigh of waste is $7.50/ton. The overall recovery is 92%. a. Calculate the BESR. BESR = [(0.006*0.92*1.63*1000) – (6.8)]/7.5

12.3 Primary Copper Smelting

The copper anode is dissolved and deposited at the cathode. As the copper anode dissolves, metallic impurities precipitate and form a sludge. Cathode copper, 99.95 to 99.96 percent pure, is then cast into bars, ingots, or slabs. 12.3.3 Emissions And Controls Emissions from primary copper smelters are principally particulate matter and sulfur oxides
