Large chromite deposits are mainly found in South Africa, Zimbabwe, Russia and Cuba. Chrome ore distribution in the world
Keith Liddell is the inventor of the Kell Process, having conceived the concept initially as a treatment route for PGM concentrate from the UG2 reef. Chromite contained in UG2 concentrates presents challenges in smelting, with constraints being placed on the amount of chromite that flotation concentrates can contain reducing flotation recovery.

cascade configuration with final concentrate being pulled from the re-cleaner cells. This mill-float configuration is commonly termed MF1 in South Africa. The primary grind was coarse limiting the risk of chrome entrainment into the final concentrate, but also limiting PGM recovery due to its inherent tendency not to recover more finely
Most of the worlds known chromite occurs in two stratiform deposits the Bushveld Complex in South Africa and the Great Dyke in Zimbabwe. Other important stratiform deposits include the Stillwater Complex in Montana, the Kemi Complex of Finland, the Orissa Complex of India, the Goias in Brazil, the Mashaba Complex of Zimbabwe and small deposits in Madagascar.
In the electrolytic process, milled high-carbon ferrochromium is leached by a mixture of reduced anolyte (electrolytic solution recycled from the anode side of the smelting cell), a chrome alum mother liquor based on a solution of ammonium sulfate recycled from a later stage in the process, and sulfuric acid. The resultant slurry is cooled, and silica and other undissolved solids are filtered from the solution.

Aug 04, 2021 The South African platinum industry has advanced into an era of predominantly mining and processing Upper Group Two (UG-2) ore to extract Platinum Group Metals (PGMs). Flotation concentrates derived from processing UG-2 ore are typically characterized by high chrome contents (3 wt.%) which are not amenable to conventional PGM smelters. The net effect of high chrome, inter alia,
