flowsheet has been conceptualised for integration into a standard platinum process which involves milling, flotation, smelting, acid pressure leaching of the matte and finally high pressure chloride leaching of high-grade PGM residue material. Running parallel to this, any low-grade concentrate
Abstract The availability of oxidized PGM ore deposits, at or near the earths surface, present lucrative prospects for future PGM production owing to the large resource estimates, the relatively high PGM grades and they can be mined through relatively lower-cost open-pit mining processes. However, these oxidized PGM ores are currently not mined or treated due to insufficient recoveries using ...
In this thesis, process options for the recovery of platinum group metals from cyanide solutions were identified with different flowsheet alternatives developed utilizing these options. Simulations were made for the different processing alternatives with the objective of finding the alternative flowsheet to maximise net present value.
