2022 AUG 01 (NewsRx) – By a News Reporter-Staff News Editor at Mining & Minerals Daily Daily – Investigators publish new report on Mining and Metallurgy. According to news reporting from Guangzhou, People’s Republic of China, by NewsRx journalists, research stated, “A stable and continuous leaching process for niobium and tantalum extraction from ferrocolumbium tantalum (FT) was developed. The effects of initial concentration of HF and H2SO4, grinding fineness, leaching time, and temperature on the leaching rate of Ta, Nb, Fe, and Si were studied.”
