In this paper, an experimental study was performed to document the characteristics of underwater electrical explosions involving different wires made from 15 different metals/alloys.

Material with a size smaller than 0.1mm in alluvial gold mine generally does not contain the gold concentrates. Gold ore with a size smaller than 0.1mm is generally named floating gold and it is difficult to be recycled during the extracting process. For the ore slime with same size grade, it can threaten the normal dressing work.

Despite having the world's largest reported reserves of gold, platinum group metals (PGMs), chrome ore and manganese ore, and the second largest reserves of zirconium, vanadium and titanium, the level of value-added mineral beneficiation undertaken in South Africa is low, with activities in the mining sector dominated by …
