grade in mineral processing

Optimizing for grade or profit in mineral processing ...

Four functions are defined: feed, selectivity, composition and criteria. After defining the criteria function that is to be optimized, the general method of optimization is shown in closed form. Two examples are given. That optimum grade and recovery do not coincide is proven.

Mineral Processing - an overview ScienceDirect Topics

Mineral processing or mineral beneficiation or upgradation involves handling of three primary types of ROM ore material which has been blasted, fragmented and brought out from in situ position. These materials can be used directly or by simple or complex processing and even applying extractive metallurgy like hydrometallurgical or pyrometallurgical methods.
