Since ground calcium carbonate is a naturally mined material, impurities exist in all ore bodies. Almost all contain some dolomite (CaMg(CO 3) 2) with a Mohs of 4, while others contain mica (Mohs 3) or graphite (Mohs 1-2). None of these softer minerals are of concern for abrasion. However, almost all GCC has some silica (Mohs 7) present.
When silica ore contains many impurities minerals, only scrubbing, desliming and magnetic separation can not purify the silica into high purity quartz, in order to further improve the silica purity and impurity content, flotation method is usually used.Flotation separation is in order to remove feldspar, mica and other non-magnetic accompanying impurity minerals of the silica minerals.
