Abstract:
     The invention relates the mineral separation process for low-grade collophane. The method comprises the following steps: carrying out dense-media dressing ore for low-grade collophane, getting the finished ore, then carrying out double reverse flotation, removing magnesium and silicon, and getting the phosphor concentrate. The method transforms the low-grade cellophane to high-grade concentrate, and recovery ratio is more than 80%, solving the problem that the low-grade cellophane is hard to utilize in industry.
