In simple terms, the primary aim of process control is to maximize efficiency of the process: achieving maximum production at minimum cost. The quality of the final concentrate determines the success of further downstream process and the optimum outcome requires proper characterization and optimization of the process.Web

Energy Use in Comminution. Grinding activities in general (including coarse, intermediate, and fine grinding) account for 0.5 pct of U.S. primary energy use, 3.8 pct of total U.S. electricity consumption, and 40 pct of total U.S. mining industry energy use. Large energy saving opportunities have been identified in grinding in particular.Web

In the extractive industries, screening is an essential process that – when done correctly – can considerably reduce costs. It is often overlooked, but it offers an opportunity to improve efficiency and return on investment. Therefore it's important to understand how screening works and how it can help increase the value of your operation.Web

the physical properties of the minerals in the ore. Four general types of operation are carried out: 1. Comminution – particle size reduction by dry crushing of "run-of-mine" ore followed by grinding of dry or slurried material; 2. Sizing – the separation of particles by size, either by screening, or by classification. Classification ...Web
