[{"type":"text","content":" Not for distribution to U.S. newswire services or for dissemination in the United States OAKVILLE, Ontario, June 07, 2019 (GLOBE NEWSWIRE) -- Giyani Metals Corp. (TSXV:EMM) (FRANKFURT:KT9) (WKN:A2DUU8) (“Giyani” or the “Company”) is pleased to announce the completion of the solvent extraction phase of its on-going hydrometallurgical testing program. The extraction tests were performed on manganese mineralized material taken from the Company’s K.Hill deposit in Botswana. The final stage of the program, electrowinning, is underway and is expected to be completed in the near future. The solvent liquid extraction process is a circuit combining extraction, stripping and precipitation stages. The tests were performed by Lab4 Inc. and the Dalhousie Minerals Engineering Centre. The purpose of the extraction tests is to purify the leached solutions that were obtained from the acid leaching phase for samples MT10, and MT11. Leaching results for these two samples were announced in a news release on May 6, 2019. Purifying the leached solutions from deleterious metal ions results in a highly pure manganese solution that is suitable for electrowinning to produce high-purity electrolytic manganese metal (“HPEMM”), a key component that is needed for the production of batteries for the growing electric vehicle market. The table below highlights the extraction results Sample Mn ppm Mn Recovery Fe ppm Fe Recovery pH MT10 16908 95.8% 30.3 1.2% 3.0 MT11 12222 96.7% 0.2 <1.0% 3.65 The manganese recoveries are above 95% and highly suitable for the overall process. In addition, the iron recoveries are within the acceptable limits for the subsequent electrowinning phase. These recoveries can be further fine-tuned in the final circuit design by adjusting key leaching and extraction parameters potentially resulting in higher manganese recoveries and lower iron recoveries. Robin Birchall, CEO of Giyani commented: “We are very pleased with these extraction results as they represent the most technically challenging steps of the overall SX-EW process. The results bring us one step closer to finalizing the hydrometallurgical process route to making our intended end product, EMM. The key takeaway from these results is that we can achieve economically viable compounded recovery levels at the leaching and extraction phases and produce a manganese solution tha...
