Waste waters from copper ores mining/flotation in‘Bučbim ...
2007-7-15 Open pit mining, ore dressing and flotation in Bučbim mine are accomplished by using vast amount of water. A complex water circulation scheme is employed, and this one is necessarily accompanied by water losses. ... In this process, part of the flotation waste water enters the nearby watercourses, thus contaminating them with heavy metals ...

2020-1-8 high operating cost, most platinum mine operations in South Africa have drifting towards mining and processing UG2 ore. Most mines process the UG2 ore from open pits and routinely suffers from low and erratic platinum group element (PGE) flotation recoveries. This is due to changes in mineralogy of the ore as a results of oxidation.

PT Freeport Indonesia (PTFI) currently employs two mining methods, the open-pit mining method in Grasberg, and underground mining. Ore extracted from the mine is hauled to the mill to be crushed and ground into very fine particles. This is followed by a flotation process using a reagent based on alcohol and lime to separate concentrate ...

Major Mines Projects Nchanga Mine
The west mill comprises two distinct circuits: the copper comminution circuit for underground ore, the copper flotation circuit for open-pit and underground. The copper comminution circuit crushes and mills ore from the Nchanga underground mine ahead of the flotation circuit and has a RoM capacity of approximately 3.0 mpta.
