The maximum extraction of MgO in the concentrate was seen for samples with very fine particles because of the high selectivity toward freely-moving fine particles. The gravity concentration method gave a concentrate that contained 43.85% MgO and constituted 39.8% of the extractable MgO. The tailings contained 61.41% talc for 89% …
