The opinions are solely those of MEI's Dr. Barry Wills, Editor-in-Chief of Minerals Engineering, recipient of the IMPC Distinguished Service Award (2014), IOM3 Medal for Excellence (2017) and honorary professorship from Central South University, China (2018).

Extractive metallurgy - Wikipedia

Mineral processing begins with beneficiation, consisting of initially breaking down the ore to required sizes depending on the concentration process to be followed, by crushing, grinding, sieving etc. Thereafter, the ore is physically separated from any unwanted impurity, depending on the form of occurrence and or further process involved.
