Research on the beneficiation process flow of scheelite laboratory
Entrusted by a mining company in Wenshan Prefecture,the laboratory flowsheet beneficiation process test of Scheelite ore in a mining area in Yunnan Province was carried out.On the basis of studying the properties of raw ore,the condition test was carried out to determine the appropriate coarse grinding fineness,H2SO4,Na2SiO3,T201,AL2(SO4)3,etc,The final process flow and results obtained are:raw ore-200 mesh accounts for 70%,H2SO4 accounts for 6000g/t,Na2SiO3 accounts for 3000g/t,T201 accounts for 340g/t,Al2(SO4)3 accounts for 200g/t,and the sample contains WO30.82%and CaF216.94%.Using the priority flotation process,the scheelite concentrate meets the quality requirements of YS/T231-2007 scheelite grade II III,and the concentrate meets the FC-95 quality requirements of YB/T5217-2002.
