The method of storing tailings, the waste materials left over after the valuable parts of mined ore have been extracted, varies based on several factors. The local geography, precipitation levels, seismic activity in the region, the specific mineral being extracted, and the proximity of the mine to residential areas all play a role in ...

During production of calibrated (sized) ore, more than 50 % of the generated fines and rejects (Slimes) cannot be directly utilised in iron making due to its unfavourable granulometry, low iron content, high alumina and silica content. Approximately 10–20 % of the process plant input is discarded as slimes into slime ponds/tailing dams. Tailing …

Flotation, when first introduced between 1913 and 1916, was used primarily to reduce losses of copper in the fine tailings of gravity plants. From an accessory to gravity methods, flotation very rapidly became a major process and finally, from 1923 to 1927, all but eliminated the gravity method in the treatment of low-grade sulfide copper …
