beneficiation results using gravity separation like multi gravity separator (MGS), particularly in finer size ranges was encouraging. The result of ore-gangue mineralogical studies were found quite useful in evaluating the separation efficacy of gravity separation process. The process mineralogical data corroborated well with beneficiation results.

Oct 07, 2020 Beneficiation was done with log washers, mechanical jigs, heavy media separation, and in some cases, hand cobbing. The advent of extensive mechanized mining caused a sharp decrease in production of these deposits due to their small size. Pyrite and marcasite mining was similar to that of the filled-sink ores, as the deposits were very similar.
