• Silica Sand Purification Project of Jianji Mining co. Ltd.

    The silica sand is used to make high-end glass so there is a high requirement for its purity that the content of Fe2O3 is below 90ppm. In order to achieve this effect after lots of tests and technical exchange we designed a set of process scheme of grinding and coarse-to-fine magnetic separation. The raw ores contain 0.06 Fe2O3 (600ppm).
