به خواندن ادامه دهیدThe mining of PGM ores is through conventional underground or open cut mines. The next stage is grinding and gravity-based (or dense media) separation, followed by flotation to produce a PGM-rich concentrate. The run-of-mine ore grades are typically several g/t, while concentrates are some hundreds of g/t [4].
