Test on Mineral Processing of a Low Grade Phosphate of Mabian in Sichuan Province
-
Abstract
This is an article in the field of mineral processing engineering. Chemical components, mineral compositions and embedded features of the low grade phosphate had been studied. The main valuable mineral in the ore was collophanite and the main gangue mineral was dolomite. The disseminated extents between valuable mineral and gangue mineral were very small so single reverse flotation method had been used in the article which could make the ore utilize by low lowcost. Through many tests and the beneficiation technological processes of the low grade phosphate had been ascertained that the grinding fineness was 65% below 0.074 mm, and once rougher flotation, twice well-chosen and twice scavenging, and the phosphorus ore concentrate had been gained which yield was 43.97%, P2O5 grade 33.86%, MgO grade 1.35% and the recovery of P2O5 was 81.84% when the raw ore’s P2O5 grade was 18.44% and MgO grade was 9.52%. In this way the cost was low and the low grade phosphate could be utilized effectively.
