The flotation concentrate contains sufficient copper for it to be suitable for smelting to recover the metal Silver, gold and platinum group metals present in copper ores follow the copper in both the flotation circuit and the smelter, and are recovered in the final, electrorefining stage Electrorefining is discussed in the final Section
The platinum-group metal content was more than twice that of a rougher concentrate, and the Al2O3 and CaO contents were significantly lower (see table 7) Because flotation concentrates would be subsequently treated by smelting-leaching or direct leaching techniques to recover platinum-group metals, impurity contents are an important consideration

The six platinum group metals (PGMs) occur together in nature alongside nickel and copper Mineable deposits of PGMs are very rare, with annual production amounting to around 400 tonnes, several orders of magnitude lower than many common metals Due to their economic values and higher quantities, platinum and palladium are the most important .
Hello, in the flotation of Platinum Group Metal Ores, is it considered wise or cost effective to introduce pH control? Is there any mine that mine PGMs that does pH control in their metallurgical plants?The reason why i ask is because i did some test works I wanted to check the relations
Froth flotation is a process for selectively separating hydrophobic materials from hydrophilicThis is used in mineral processing, paper recycling and waste-water treatment industri Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century
demand that the individual platinum group metals be separated from the other metals and from each other to high purity, with high yield and with a high percentage recovery Refining of platinum group metals consists of several stages: I Ore concentration by physical techniques such as flotation 2
Sometimes gravity separation is employed prior to flotation; this results in a concentrate containing up to 50 percent platinum metals, making smelting unnecessary Extraction and Refining The separation chemistry of the platinum-group metals is among the most complex and challenging of metal ,
