After two years of technical research, the plant successfully titanium grade 2 developed a "full utilization of Panzhihua 74% grade titanium slag of molten salt chlorination fine titanium tetrachloride production of" advanced technology, becoming the first use of 74% grade titanium slag of molten salt chlorination fine titanium tetrachloride production enterprises, vanadium and titanium resources in Panxi provides a new path utilization.
It is reported that 74% of the whole Panzhihua grade titanium slag with low volume, high impurity content, the higher chlorine content in the exhaust, high production of waste salt, lye consumption is large, therefore, only as titanium dioxide feedstock, can not as titanium sponge production of raw materials. After nearly two years to carry out the production of chlorinated research, from April 1 this year, the plant optimization through the medical grade titanium adoption of technology, equipment upgrading, refining operations and other measures in the chlorination process, the smooth realization of the full 74% grade titanium Panzhihua production of refined molten slag chloride titanium tetrachloride major technological breakthrough, can reduce the cost per ton of titanium sponge 1329 yuan.
