Abutment — In coal mining, (1) the weight of the rocks above a narrow roadway is transferred to the solid coal along the sides, which act as abutments of the arch of strata spanning the roadway; and (2) the weight of the rocks over a longwall face is transferred to the front abutment, that is, the solid coal ead of the face and the back abutment, that is, the settled packs behind the face.
In mineral processing or metallurgy, the first stage of comminution is crushing. Depending of the type of rock (geometallurgy) to be crushed, there are 2 largely different techniques at your disposition for crushing rocks. In principle, compression crushing is used on hard and abrasive rocks by placing them between a high wearresistant plate/surface.
A ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as .
Flotation, in mineral processing, method used to separate and concentrate ores by altering their surfaces to a hydrophobic or hydrophilic condition—that is, the surfaces are either repelled or attracted by water. The flotation process was developed on a commercial scale early in the 20th century to
ing or crushing. Mineral processing involves the use of processes that cause a significant physical/chemical change to the ore or minerals. For example, the smelting of copper or lead is commonly recognized as a mineral processing ac tivity. While wastes from benefication are exempt from RCRA under the Bevill exclusion, wastes from mineral pro

Abrasive Technically any material can be used to abrade another materials. For industrial application, however, abrasives are minerals from a select group of very hard minerals used to shape, finish, or polish other processes that grind, finish, polish, lap, or hone, abrasives are typically limited to synthetic minerals with the exception to diamond and garnet.
