High pressure grinding rolls (HPGR) are used for size reduction or rocks and ores. They compress the feed material between two rotating rollers, one of which is in a fixed position and another roller that is floating. The two rotating rollers generate such a high pressure that it grinds the feed material to the desired smaller grain size.
In many cases, the valuable minerals are mixed with gangue, commercially useless material, and the ore must be separated. The first step of many separation processes is comminution (size reduction) followed by classification (separation by particle size) either for further grinding
Abrasive minerals are chosen by their hardness. The basic abrading principle is a harder material chipping, abrading, or wearing away a softer workpiece material. The abrasive minerals generally run between 7 and 10 on the Mohs scale. Below is a chart on abrasive mineral

Pumice is a stone, not a mineral, a volcanic product with a very fine grain. Its hardest mineral is quartz, so it has a gentler action than sanding abrasives. Softer still is feldspar (Mohs 6), which is most famously used in the Bon Ami brand household cleaner. For the most delicate polishing and cleaning work,
