Gravity concentration, past, present and future ...

Abstract. Gravity Concentration has been used for the beneficiation of minerals for centuries with little change in the methods used from 500 B.C. to 1550 A.D., and in fact some of these methods, such as the sluice and hand pan, are used to this day. Change when it came was the result of a number of factors, most importantly the discovery and ...
