low grade dolomite slime uses in crops

Dolomite is used as a source of magnesium for magnesium-deficient soils. It can also be used as a source of magnesium for livestock. However, very high rates are required for this purpose (5 t/ha or greater). A Department of Agriculture study at Camperdown showed that 12.5 t/ha needed to be applied to obtain an effect. Experience is that ...

Optimization of thermal beneficiation of a low grade

Apr 01, 1995 Abstract. Low grade dolomitic phosphate rocks have no direct use and are rejected all over the world. Substantial amounts of such low grade phosphorites are found along with high grade ore in some areas of Hazara (Pakistan). In the method described, thermal beneficiation is carried out to see the effect of temperature, time and particle size ...

Innovations in beneficiation technology for low grade

Mar 15, 2017 As high grade deposits of phosphate rock are being depleted day by day in the world, future sources will be derived from low grade rocks containing various impurities. Low grade phosphate rocks are not suitable for direct use in acidulation plants unless their tricalcium phosphate (TCP) content is increased to 70% or more, using conventional methods such as crushing, screening, and drying, or ...
