Copper flotation: general use relatively simple process, after a period of grinding, fine -200 mesh about 50% to 70%, 1 roughing, 2 or 3 times selected, 1 or 2 times sweeping election . Disseminated copper minerals, such as relatively small size, may consider the stages of grinding and separation process. Treatment spot copper concentrator, they use rough concentrate regrinding - selected selection stage grinding process, and its essence is mixed - flotation process. First by a coarse, rough election, sweep the election, and then grinding and then rough Concentrate selected by high-grade copper concentrate and concentrate. Ground level of crude accounts for about 45% -200 mesh 50% -200 mesh and then finely ground level about 90% to 95%.
