Mining

Gangue occurs in the ore body as large clumps. It is usually denser than the valuable minerals because it contains a high concentration of silicates. Sorting can help the progressive upgrade of ore concentration. This enables the mill to process at a very high concentration, without gangue driving down the average.

PGM

Talc is a naturally floating gangue mineral found in PGM ores and has a hydrophobic nature that increases with milling intensity. As a result, talc is a major concern for PGM producers who are mandated with fine grind milling. Revadep Tal-D adsorbs onto the talc surface, making the surface hydrophilic, thus reporting to the tailings

How to determine the raw material of high purity quartz

10-06-2021In addition to gangue minerals and inclusions, a small amount of impurity elements exist in quartz crystal in the form of isomorphism, forming lattice impurities in quartz raw materials. In the current process of high purity quartz mineral processing, lattice impurities can hardly be removed, which determines the limit of raw material purification potential.
