Grade Engineering (G.E) refers to a range of integrated strategies aiming to improve feed grades by removing low grade uneconomic material prior to energy intensive and inefficient grinding (Walters, 2016).In this work the impact of preferential grade by size deportment and differential blasting for grade on comminution circuit performance (throughput) is investigated.

A computational model for use with DEM (Discrete Element Method) is proposed for the five mechanisms applying to particle comminution in AG, SAG and coarse feed ball mills. Chipping and rounding are mechanisms that lead to preferential mass loss from corners and edges of particles and which produce shape change for the particles as well as size reduction.

Many studies used buffers to control pH during the reaction of ZVI, but the effect of buffer solutions received little attention. In this study, the effect of buffers on selenite (Se(IV)) and selenate (Se(VI)) removal by ZVI was systematically investigated. It was found that the addition of buffers can hinder the corrosion of ZVI, and then affect Se removal.

Comminution is a technical term used in mining and metallurgy to refer to the process of reducing the size of rocks or minerals by crushing and grinding. The main objective of comminution is to free valuable mineral particles from gangue (unwanted material) so that they can be processed and recovered in later stages, such as concentration or leaching.
