Jul 22, 2021Reefs such as the BR have nonlinear or antagonistic (or synergistic) blending effects, and addition of the BR ore biases the blend toward that of poor-quality ores, thus affecting gold recoveries during leaching. This can significantly affect production accounting, where ore blends are modeled purely additively (van Tonder et al. 2021).

The planes across weaker bonds are more susceptible to breakage, and the resulting flat surfaces are called cleavage planes. When well-developed and easily observed, the degree of perfection, the number, and the angles between cleavage surfaces are properties that help to identify a mineral.

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
