Abstract
A new process of extracting titanium from vanadium–titanium magnetite (VTM) in the Panxi area in Sichuan, China is introduced in this work. Various experiments, including reduction–magnetic separation, leaching and hydrolyzing experiments, are carried out. The results show that the optimum conditions for leaching experiments are an acid/slag ratio of 4:1, a leaching temperature of 60 °C, a leaching time of 80 min, and a liquid/solid ratio of 3.2:1. The leaching rate of titanium in Ti-bearing slag is 92.41%. The optimum conditions for hydrolyzing experiments are an H+ concentration of 0.75 g·L−1, hydrolyzing temperature of 100 °C, and hydrolyzing time of 180 min, and the hydrolyzing rate of titanium in acid leaching liquor is 96.80%. After the leaching and hydrolyzing experiments, the recovery rate of titanium from the Ti-bearing slag is 89.45%.
Highlights
Vanadium–titanium magnetite (VTM) owes its extremely high and comprehensive utilization value due to abundant associating and valuable elements such as iron, vanadium and titanium [1]
VTM has been treated by BF (Blast Furnace) ironmaking and a BOF (Basic Oxygen Furnace) vanadium extracting/semi-steel smelting process in China [4]
A mountain of titanium in VTM enters the BF slag, which is piled along the Jinsha River and is difficult to utilize
Summary
Vanadium–titanium magnetite (VTM) owes its extremely high and comprehensive utilization value due to abundant associating and valuable elements such as iron, vanadium and titanium [1]. A mountain of titanium in VTM enters the BF slag, which is piled along the Jinsha River and is difficult to utilize. This leads to a serious issue of environmental pollution and a large supply of valuable titanium is lost. In order to achieve the comprehensive utilization of titanium from ilmenite and VTM, a large number of processes for extracting titanium have been put forward nowadays [5,6,7,8]
