·Sedimentary PMWR considered to be a phosphate loss is characterised by low grade phosphate ore 5 16% P 2 O 5 It is extracted in an open pit and disposed of on the surface; this ore can be reprocessed more cheaply than either the material extracted from underground mines or metamorphic low grade ore 3 10% P 2 O 5 Krasnova et al
·The current beneficiation study examines the potential for separating ultrafine low grade iron ore materials using a circulating type air classifier Statistical analysis using Response Surface Methodology RSM was implemented for optimization of the separator critical processing parameters to achieve sharp separation at a cut size as fine
·Screening of powders is an important unit operation for industrial separation of solid particles but to design equipment for a specific material requires considerable time and material which encourages the use of mathematical models to predict or characterise the goal is to represent the particle size separation during
Drilling results for base metals are typically reported in percentage per tonne % while precious metals are reported in grams per tonne g/t As an investor it s crucial to understand if a drill result indicates low medium or high grade mineralization as this can provide insight into the potential financial outcomes of the deposit
·The goal of the present work was to study the recovery of copper nickel and platinum group metals PGMs Pt and Pd from low grade copper nickel ore containing pyrrhotite pentlandite and
