Kyanite and Sillimanite Beneficiation Process

Kyanite and Sillimanite Reagent Combinations. Sulphonated-petroleum collectors with alcohol frother and with sulphuric acid to a pH of 3.0 are the most common reagents for flotation of kyanite after conditioning. If sulphides occur in the ore they may be removed by regular xanthate flotation before de-sliming. Market Specifications
