The solvent extraction separation of molybdenum and copper from acid leach residual solution of Chilean molybdenite concentrate
A procedure for recovery and separation of molybdenum (VI) and copper (II) from acid leaching residual solution of Chilean molybdenite concentrate by solvent extraction is studied. The process for the recovery of metals ...
Optimizing open-pit block scheduling with exposed ore reserve
(Southern African Inst Mining Metallurgy, 2016-07)
A crucial problem in the open pit mining industry is to determine the optimal block scheduling, defining how the orebody will be sequenced for exploitation. An orebody is often comprised of several thousand or million ...
In situ mining through leaching: experimental methodology for evaluating its implementation and economic considerations
(The Southern African Institute of Mining and Metallurgy, 2015)
Rising costs in the mining industry have necessitated a search for alternative methods for the recovery of metals from deposits that are no longer economically or environmentally exploitable by conventional mining. These ...
Methodology for evaluation of mud rush risk in block caving mining
(Southern African institute mining metallurgy, 2017)
Mud rushes are sudden inflows of fine wet ore within underground mines; they can harm people and equipment as well as cause production delays. Block and panel caving mines are prone to mud rushes in their production levels, ...
Geotechnical characterization of ore related to mudrushes in block caving mining
(South African Institute of Mining and Metallurgy, 2017)
Mudrushes are sudden inflows of mud ore into underground miningfacilities. They may cause harm to people and equipment, productiondelays, dilution of ore, and mine closure. The aim of this work is to charac-terize, by ...
