· The coppercobalt and zinc values in the ore can be leached using sulphuric acid solutions in a slurry leach process. While the dissolution of the valuable metals into the leach solution is relatively straightforward, the subsequent separation of metal containing solution from leached solids has historically been challenging.
Manganese extraction of >90% can be obtained by leaching the ore at 90˚C for 8 hours in sulphuric acid medium. With the variation of temperature, the rate of leaching increased with the increase of ore to newspaper ration. Zhang et al. [66] introduced a hydrometallurgical process for the recovery of metals from spent secondary batteries. In ...

Ore is crushed to a finely powdered form and treated with rapidly flowing current of water. During this process the lighter gangue particles are washed away by the running water. This method is generally applied to concentrate the native ore such as gold and oxide ores such as haematite (Fe 2 O 3 ), tin stone (SnO 2 ) etc.
The Chemical Dissolution Chamber is the first machine in the x5 ore processing setup. It turns raw ores into slurry using Sulfuric machine uses 100 of sulfuric acid for every ore dissolved and outputs 1000 of slurry. This slurry needs washing in the Chemical that unlike most Mekanism machines this one has fixed "in" and "out" sides for the mineral flow.
