PGM Ore Processing At Impala's UG-2 Concentrator

ug-2 platinum group mineralisation is highly complex. from the metallurgical perspective, however, pgm speciation is a minor issue as it tends not to dictate floatability. for example, qemscan studies of the impala ug-2 plant feed have shown that the mix of fast-floating pgm is similar to that of the slow floating pgm, and the unfloated pgm.extractive metallurgy of nickel, cobalt and platinum group,this book describes and explains the methods by which three related ores and recyclables are made into high purity metals and chemicals, for materials processing. it focuses on present day processes and future developments rather than historical processes. nickel, cobalt and platinum group metals are key elements for materials processing..tharisa minerals: vision 2020 on the cusp of realisation,“the vulcan plant will use a multi stage approach to extract the current in-line, or “fresh”, tailings, which range between 7% and 12% chrome content, from the combined feed of the genesis and voyager plants before it is deposited onto the tailings dump,” explains graulich, noting that vulcan plant aims to extract an additional 3% to 7% of extra chrome through vulcan so that we put as little tailings.metallurgical pilot plants – core group,we specialise in the design and execution of complex integrated process pilot plants, and have expertise in this across most mineral processes. core has installed and operated numerous pilot plants, including a 1.5 tpd continuous grind-flotation-hydrometallurgy-metal recovery demonstration plant. operation of a pilot plant to a bankable standard is
