Study on Beneficiation of Micro-fine Particle Fluorite Ore Associated with Ag
Fluorite oreassociated with a small amountpyrite,natural silver and silver pyroxene.Fluorite,pyrite,natural silver and silver pyroxene have extremely fine dissemination size.Aiming properties of fine-grained dissemination,Fine grinding was carried out with 92.59%-0.074mm.Silver concentrate of floatation containing1934.79g/t silver,silver recovery of 70.31%,and fluorite concentrate of floatation containing97.35%CaF2,0.77%CaCO3,CaF2 recovery of 78.72%,could be obtained by the flowsheet of preferential flotation of sulfide,and alkaline flotationof fluorite roughing,and weak-acid flotation of regrinding fluorite concentration
