Abstract

Abstract

The recovery efficiency of fine-grained olivine pyroxene ilmenite from a concentration plant in Panxi area is low, which brings about high cost of flotation reagents and low annual output of titanium concentrate. To solve these problems, a kind of gravity concentration process, i.e., the new type “spiral + suspended vibration cone surface mineral processing”, is creatively developed. By using the new technique, the yield increased by 8.24%, the grade of flotation feed TiO₂ increased by 2%, and the grade of TiO₂ tailings decreased by 4% compared to that of current high-intensity magnetic separation process, the cost of flotation reagents is greatly reduced, and 60, 000 tons of titanium concentrate can be increased every year. In this way, the efficient recovery of this type of ilmenite can be realized.
