2022年2月15日 When cassiterite polymetallic sulfide ore is being ground in the ball mill, the contradiction between over grinding of cassiterite and under grinding of sulfide ore is inevitable due to their mechanical property differences. In this paper, a selective grinding characterization method is proposed to optimize the grinding of cassiterite polymetallic
خبير الاتصالIt is not based on 'solubility'. Rather, it is based on the principle of differential wettability of the ore and gangue particles. Electromagnetic separation works when either ore or gangue are magnetic (attracted to magnets) in nature. Crushing and grinding happen before concentration. It is not a concentration process at all.

2023年1月25日 Definition of Concentration of Ore. Ore concentration is the chemical process of eliminating impurities like sand, rocks, silt, grit etc. from the ore to extract the metals in their pure form. In other words, it is the method of separating ore from the gangue, as the gangue or matrix particles are the valueless substances that are of no use.
