copper ore comminution flow

The efficiency of copper ore comminution: A

01-08-2017  Comminution is the breaking of larger rocks into smaller ones through crushing, grinding, or other processes. In copper mining, it is used to crush the ore to a fine powder. In this powder form, froth flotation tanks can be used to separate the copper concentrate from the gangue (the remainder of the mined material).

Energy Consumption in Mining Comminution

3. Comminution and Mill Energy Requirements Comminution includes both crushing and grinding. Initially, ore is reduced in size by crushing rock to a size that makes it manageable. Crushing is accomplished by compression of the ore against rigid surfaces, or by impact against surfaces in a constrained motion path. Crushing is usually a dry process, and

Comminution - Wikipedia

Comminution is the reduction of solid materials from one average particle size to a smaller average particle size, by crushing, grinding, cutting, vibrating, or other processes. In geology, it occurs naturally during faulting in the upper part of the Earth's crust. In industry, it is an important unit operation in mineral processing, ceramics, electronics, and other fields, accomplished with many types of mill. In dentistry, it is the result of mastication of food. In general medicine, it is one of the most traumatic forms of bone fracture.
