Low Grade Rock Phosphate Wanted Industries

Use of phosphate rocks for sustainable agriculture

In some low-grade commercial deposits, this may be as low as 4 percent. In the phosphate industry, the phosphate content of the rock is usually expressed as tricalcium phosphate and traditionally referred to as bone phosphate of lime (P 2 O 5 × 2.1853 = BPL). The latter term is reminiscent of the time when bones were the principal source of

Phosphorite Wikipedia

Phosphorite, phosphate rock or rock phosphate is a non-detrital sedimentary rock which contains high amounts of phosphate minerals.The phosphate content of phosphorite (or grade of phosphate rock) varies greatly, from 4% to 20% phosphorus pentoxide (P 2 O 5).Marketed phosphate rock is enriched ("beneficiated") to at least 28%, often more than 30% P 2 O 5.This occurs through washing, screening

Phosphate is a relatively low unit-value commodity. Therefore, most phosphate rock extraction operations tend to involve surface mining, large-volume extraction and reasonably low transport distances to major markets (Bartels & Gurr 1994). In comparison to many other mineral commodities, the demand for phosphate rock appears relatively predictable

Beneficiation of refractory rock phosphate by calcination

Abstract. Separation of refractory rock phosphate (P 2 O 5 = 11.5%) from the Dalir area, Iran, containing quartz, calcite and other impurities, by calcination and flotation processes has been successfully used to upgrade the phosphate values. Petrographic studies of this ore showed that collophanite was the major phosphate mineral and the main gangue minerals were calcite, dolomite and quartz.
