Experimental Study on Flotating the Ore from A Copper-iron Mine
The mine in a certain place is a large-scale Cu-Fe mine combining mining and flotation,mainly engaging in copper&iron concentrates,with gold and silver as the subordinates.The mine is committed to implementing the strategy for the energy conserva-tion and emission reduction to improve the comprehensive utilization of resources,as well as continuing the Green Mine initiative,endeavoring to develop technological innovation,realizing the technological breakthroughs and optimizing econo-technical norms.The ore,defined as a raw Cu-Fe mine,is prepared standardly in accordance with the Laboratory Sample Processing Scheme and sampled professionally.The experiment aims to study the flotation of the Cu-Fe mine.The best flotation conditions of the flotation categories of the mine are determined by analysing the property of the mine and its flotation technological process,based upon the best fineness of grinding,the types of collectors and the experiments of the dosages of the flotation reagents.Under the above condi-tions,the closed-circuit experiment,through the flotation technologies that include"Primary roughing,secondary scavenging and primary cleaning"is adopted to the flotation with T211(Collector C)as the collector and pine oil as the frother.20.25%of the grade of Cu concentrates,93.12%of the recovery of Cu,75.26%of the recovery of Au and 78.12%of the recovery of Ag can be obtained to realize the ideal recovery effects.
