A step forward for a new titanium leaching process

By Paul Grad |

Reed Resources Ltd. (Perth, Western Australia; www.reedresources.com) has advanced its Barrambie Titanium Project — about 600 km northeast of Perth, Western Australia — with the construction (now in its final stages) of a mini-pilot plant in Canada to demonstrate a transition from laboratory-scale batch testing to continuous operation. Barrambie is one of the world’s highest-grade titanium deposits, containing total indicated and inferred mineral resources of 47.2 million metric tons (m.t.) at 22.2% TiO2, 0.63% V2O5 and 46.7% Fe2O3, at a cut-off grade of 15% TiO2. The plant will test a proprietary chloride-based process (flowsheet), pioneered in Canada, for the recovery of TiO2, V2O5 and Fe2O3 from run-of-mine ore at a feedrate of 10 kg/d. It will test the operation of each of the major unit operations of the flowsheet on a continuous basis: leaching of the mineralized material, TiO2 precipitation, iron hydrolysis, and acid regeneration. The company says a key feature of its patented process is the acid recovery and regeneration process, which shows the potential to operate at significantly lower costs than established technologies previously evaluated by Reed. Reed will now start a pre-feasibility study of a hard-rock…
