ادامه مطلبEffective beneficiation can be achieved by using various processes, depending upon the liberation size of phosphate and gangue minerals and other ore specifications. Different processes like screening, scrubbing, heavy media separation, washing, roasting, calcinations, and flotation may be used ( Lawver et al., 1978 ).
ادامه مطلبThe recent mining history in Jordan was established by Jordan Phosphate Mines Company (JPMC) in 1935. Prospecting of minerals and exploration programs in Jordan continued for many years after the ...
ادامه مطلبMoreover, the concentrate produced by beneficiation of igneous phosphate is characterised by low carbonate and contaminant contents in comparison to some sedimentary phosphate rock (Pufahl and Groat, 2017). The grade of the phosphate ore depends on the total phosphate content and the impurities (Watti et al., 2016).
