cobalt is a very important metal which is widely applied in various critical areas, however, it is difficult to recover cobalt from minerals since there is a lack of independent cobalt deposits in nature. this work is to provide a complete process to recover cobalt from cobalt tailings using the moderately thermophilic bioleaching technology and selective sequential extraction. It is found the maximum extraction of nickel and cobalt was observed with pretreated ore at 10% pulp density respectively within days at pH 1.5 and least extraction in case of

ball mill wikipedia. the ball mill is a key piece of equipment for grinding crushed materials, and it is widely used in production lines for powders such as cement, silicates, refractory material, fertilizer, glass ceramics, etc. as well as for ore dressing of both ferrous and non-ferrous metals. ball mills and roller mills in large power plant after ball milling and cycloning, the next step is to remove magnetic pyrrhotite from the ore, which makes up of the total pyrrhotite in the ore, depending on the ore source. fifty-four 3-ft diameter by 6-ft long wet permanent magnetic drum separators are used to recover the magnetic pyrrhotite, which is then reground into 13.5-ft by
