fluorspar crushing technique

Fire Assay Procedure

Fluorspar (calcium fluoride – CaF2) ... The nickel sulphide technique uses a 10 g of sample, 1 g powdered Ni, .8 g S, 12g soda ash, and 24 g borax. The mixture is fused at 1010 °C for 1 hr. Then it is cooled and the assayer separates the NiS matte from the slag and pulverizes the NiS matte. The pulverized matte is dissolved in concentrated HCl.
