The copper recovery rate of a copper mine in Xinjiang is only 87% and the recovery rate of associated gold is 45%, due to the change of ore properties. Through experimental research, without changing the field production process under the condition of using the new flotation reagent A8 instead of 2# oil field, small scale test and industrial test achieved good technical indexes, compared with the agent system, with a new reagent can make the copper recovery rate increased by 1.56%, the gold recovery rate in...
