Abstract
The article describes studies into process properties of wollastonite-bearing rocks of Tyrnyauz deposit with a view to developing an efficient technology for production of high-grade wollastonite concentrate. The recommended process flow diagram includes milling, screening, X-ray luminescence separation, wet electromagnetic separation and flotation. From the data of chemical and X-ray phase analyses, the produced wollastonite concentrate conforms with the Voksil-100 grade.
