Kell Process Details
The Kell Process has been developed for extraction of platinum group metals (PGM), gold, silver and base metals from PGM sulfide flotation concentrates without smelting. The innovative Kell Process allows companies with challenging platinum, base metal, refractory gold and polymetallic ore bodies to benefit from this highly efficient hydrometallurgical Kell Process to treat your Pt, Pd, Rh, Au, Ni, Co, Cu concentrates that saves on energy costs and reduces carbon tax liability. Polymetallic, base metal, PGM and gold concentrate produces can further save on transport and smelting charges and achieve much higher metal recoveries.The hydrometallurgical process has been successfully demonstrated on several different PGM and polymetallic concentrates, including those from the UG2, Merensky and Platreef in South Africa, Great Dyke in Zimbabwe and several concentrates from North and South America. It has been shown to provide high recoveries (95 to 99%) and selective extraction efficiencies for the key base metals and precious metals, i.e. Pt, Pd, Rh, Au, Ni, Co, Cu.The KellGold variation is applied to refractory gold, Cu/Au and preg-robbing gold concentrates - enabling production of refined metals at the mine site without the use of cyanide.The Kell Process is a leap forward in PGM, polymetallic, gold, lithium and base metal concentrate processing technology, by bringing enhanced economic outcomes - including much lower power consumption, efficient processing to metals in a matter of days and a range of environmental benefits.
