Kyanite Ore Beneficiation Experimental Research in Hebei

Abstract:

As high-grade refractories raw material，kyanite is widely used and the market demand is increasingly greater. The kyanite in Hebei is complicated，main chemical composition is SiO₂ 52.87％、A1₂0₃ 21.14％. The result of investigation on mineral processing technology show that desliming has a great influence on kyanite, especially acid process, the suitable lower limit particle size for desliming is 20μm. Magnetic separation process may remove iron-bearing minerals，and the iron removal rate is 87.78％．The optimum condition for magnetic separation is magnetic field conditions 1.0T. Base on the research, we can get concentrate with a grade of A1₂0₃ 58.37% and a recovery of A1₂0₃ 56.02% if we adopt magnetic separation and flotation technology.
