Due to the difficulty and complication of the iron ore processing technology, the key research point is how to extract all the valuable metals in the sulfide ore as far as possible. The regular hydrometallurgical process is not easy to operate and with low efficiency. Nowadays, the above-mentioned bacterial oxidation process is welcome adopted by its higher leaching rate and fewer energy consumption.
bioleaching technology enables the rapid leaching of valuable metals and associated metals in the sulfide ore, which truly achieves the goal of concentrate beneficiation. However, it is inevitable that has some defects like beneficiation rate influenced by reaction time, temperature easily.
Gold leaching process for your reference3 Grinding-flotation processAmong the iron ore processing technologies, the ground floating technology has the longest application time. Its working principle is: through continuous flotation, grinding, and classification processes to separate the metals from sulfide ore more accurately.
