Proceedings of the 4th World Congress on Mechanical Chemical and Material Engineering (MCM'18) Madrid Spain – August 16 – 18 2018 Paper No MMME 124 DOI: 10 11159/mmme18 124 MMME 124-1 Characterisation and Flotation of a Weathered Platinum A flowsheet has been developed for the production of rich concentrates of precious and non-ferrous metals by a complex treatment of the flotation products from South African platinum-containing chrome ores The procedure involves: autoclave leaching roasting hydrochlorination and precious metal recovery by sorption Autoclave oxidative leaching of the initial material

Flash flotation

Typical applications of flash flotation can be found in gold silver platinum and other PGMs lead copper nickel and combinations thereof It is worth noting that typically flash flotation is not extensively evaluated during a feasibility study and hence it is unknown if it would be suitable for the project ore and mineralogy This can be

Equimolar amounts of palladium nickel and platinum were completely separated from each other by successive flotations Photographs taken of the bubbles during flotation showed that at a flow‐rate of 3 1 litre/hour a mean surface area of 2 07 metre 2 passed through the cell per minute

Platinum – Palladium Flotation Summary A flotation method using mercaptobenzothiazole collector in an acid circuit was devised for preparing a platinum-palladium concentrate from Stillwater complex gabbro (Montana) Bench-scale experiments showed that rougher flotation recovered 91 pct of the platinum and 88 pct of the palladium in a

1 Froth Flotation – Fundamental Principles Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry The particles with attached air bubbles are then carried to the surface and

concentrations The traditional flotation cell consists of a stirred tank incorporating air injection In recent decades columns have appeared to offer advantages for platinum flotation This project is a comparative study of the use of column and mechanical cells as cleaners for the flotation of an UG-2 (Upper Group 2) platinum ore

The first step in this process is to crush platinum containing ore and immerse it in the reagent containing water a process known as 'froth flotation' During flotation air is pumped through the ore-water slurry Platinum particles chemically attach on to the oxygen and rise to the surface in a froth that is skimmed off for further refining

Introduction to Mineral Processing Froth Flotation Froth flotation is considered to be the most widely used method for ore beneficiation In ore beneficiation flotation is a process in which valuable minerals are separated from worthless material or other valuable minerals by inducing them to gather in and on the surface of a froth layer Sulfide and non-sulfide minerals as well

7 Flotation of Gold and Gold-Bearing Minerals 7 1 Differential Flotation of Natural and Liberated Gold Experience has shown that free gold particles can be recovered selectively against pyrite by keeping the gold particle surfaces as clean as possible of organic species and by removing any adhering slime particles (Klimpel 1997) This can
