Bornite «Mining Encyclopedia»

2015-1-28  Bornite is the important mineral of the copper ores. The major method for beneficiation is flotation. It is extracted together with other copper sulphides, with the usage as collectors, of xanthates (pH is approximately 12), and of dithiophosphates (pH is 7-8), with the usage as regulators for environment, of CaO, N 2 SO 3,H 2 SO 4,and with

For open pit mining the costs are $0.40/ton ore and a stripping cost of $0.50/ton of waste. SR = (3.00 -0.40)/0.50 = 5.2 tons of waste/ ton of ore i.e. while the stripping ratio is less than 5.2 it is most economical to mine the deposit by open pit. With mining of bench 8, another 5,000 ft 2 of ore (A 6 ) is removed.
