  2019826 · Description. Platinum (element #78, symbol Pt) is a dense, silvery-gray metal. The platinum group of elements consists of metals with similar physical properties as platinum and these elements are among the rarest in the Earth’s crust. They have high melting points, are dense or heavy and are non-reactive with other elements.

Among the available commercial classifiers presented by Mills2, hydrocyclones have been shown to be the most widely used classifiers in the target size range of 10 to 100 µm where the recovery of the platinum group metals (PGMs) from the UG2 using the flotation process is maximized. Other common classifiers such as screens …

  The complex process for refining platinum. Image from UNCTAD. A platinum flotation circuit. In a process called flotation separation, air bubbles are blown through the mixture and carry platinum particles to the surface of the bath. The platinum-rich froth is skimmed from the bath and allowed to dry into a concentrated powder.

  20191212 · Batch flotation tests were carried out on samples milled to 80% –75 μm at a slurry density of approximately 30% w/w solids. Synthetic plant water was prepared using distilled water modified by addition of ionic salts to achieve the ionic strength typical of process water at concentrator plants (Wiese, Harris, and Bradshaw, 2005).

  Potential Processing Routes for Recovery of Platinum Group …

  2017116 · The beneficiation of platinum group metals (PGMs) from pristine (unweathered) sulfide ores has conventionally been conducted through froth flotation, which typically achieves platinum recoveries of over 85%. The achieved successes of PGM concentration by flotation from the pristine sulfide ores are largely due to the occurrence …
