Minerals | Special Issue : Grinding Modeling and Energy
It has been estimated that grinding consumes up to 4% of global electrical energy and accounts for more than 50% of the total energy used in mining operations. In addition, more than 90% of the total energy supplied in beneficiation plants is dissipated as heat, kinetic energy, noise, and inefficient breakage of ores/raw material.

Mineral Processing Equipment
The extraction of copper from ore is normally carried out in three major steps. The first step, mineral processing, is to liberate the copper minerals and remove waste constituents—such as alumina, limestone, pyrite, and silica. The second step, involving either smelting or leaching, removes a large proportion of impurity elements.
OVERVIEW OF MINERAL PROCESSING METHODS
7 2.5 Grinding is the stage of size reduction (wet or dry) where the liberation size for individual minerals can be reached. Size reduction by crushing has a size limitation for the final products.
