[{"type":"text","content":"VANCOUVER, British Columbia / Jul 28, 2022 / Business Wire / Temas Resources Corp. (“Temas” or the “Company”) [CSE: TMAS] is pleased to report positive pilot plant results for the recovery of high purity titanium dioxide from ilmenite-rich anorthosite ore from its La Blache titanium (Ti) - iron (Fe) – vanadium (V) – chromium (Cr) property in Quebec. A two-phase test program was implemented to process ~830 kg of La Blache ilmenite rich anorthosite to recover a high purity TiO2 product. The La Blache property, situated on Quebec’s North Shore approximately 100 km from the city of Baie-Comeau, consists of ilmenite rich material comprising ~41% Fe, ~10.6% Ti and ~0.18% V. Temas engaged Process Research ORTECH Inc. (PRO) to apply the 50% Temas-owned ORF patented chloride process for the treatment of the ilmenite ore to recover the titanium dioxide product. The pilot plant is located in Mississauga, Ontario, Canada. Michael Dehn, CEO of Temas Resources states, “We are satisfied that the pilot plant results have confirmed the ability to produce a high purity TiO2 product from ilmenite rich anorthosites. With the 88 kg produced from the program, we are currently engaging with potential customers, and providing material for their own quality testing. Results from this pilot plant program will be used to develop our Preliminary Economic Assessment (“PEA”) on the La Blache project.” Phase 1 of the test program involved a bench-scale and mini-pilot test program to evaluate and optimize the Ti and Fe recovery from the ilmenite rich anorthosite. A two-stage mixed-chloride leaching process, which attained an overall Ti recovery of 80.6%, was undertaken. Preliminary mini-pilot solvent extraction circuits were also run to establish steady state operation conditions prior to the large pilot operation in Phase 2 of the program. It was found that selectivity was maintained in both the Fe and Ti solvent extraction (“SX”) circuits, with high purity Ti pregnant strip solution produced. The Ti-rich pregnant strip liquor underwent thermal precipitation and a total of ~88 kg of TiO2 product was recovered with an average of 99.8% purity in the two-phase test programs. The overall impurities present in the final product ranged between 0.08% and 0.26%. Based on the quality of the TiO2 product, end uses include applications as a precursor for pigments, fille...
