Argex Mining has conducted mini plant testing of the ore collected from its wholly owned La Blache deposit, located on the northern shore of Quebec. The testing has resulted in the production of 99.8% pure titanium dioxide and average recoveries of 90%. The company’s subsidiary, Canadian Titanium Limited processed the ore using Argex’s patented processing methods, referred to as the CTL Process. Argex developed the process to produce titanium dioxide, iron oxide and vanadium products directly from run of mine materials; the process entails leaching the titanium-bearing ore into a solution. Since the process operates at an atmospheric pressure, it does not require the ore to be pre treated, decreasing operating costs and making the process more energy efficient. The process also operates with a relatively low concentration of hydrochloric acid, which eliminates the need to handle chlorine, carbon or carbon containing chemicals at high pressures. Intended to examine the company’s CTL Process, the testing demonstrated the repeated and steady production of 99.8% pure titanium dioxide, directly from run of mine materials. It also found an improved and consistent titanium dioxide recovery rate of 90%.
