Separating the Platinum Group Metals by Liquid–Liquid

The platinum group metals platinum, palladium, rhodium, iridium, osmium and ruthenium together with silver and gold generally occur in nature associated with the major base metals iron, copper, nickel and cobalt and a wide range of minor elements such as lead, tellurium, selenium and arsenic, and both technical and commercial considerations demand that the individual platinum group metals be

Platinum metals-solution chemistry and separation methods

The effects of knowledge of the solution chemistry of the platinum metals on their separation by solvent extraction and ion-exchange methods are reviewed, for the period 1950-1983. The review concentrates on the chloro-complexes of these metals and indicates those areas which need more investigation or interpretation to provide adequate

Here are three main ways of refining gold mines, each operating in the cave room, the reservoir room and the barrels. In addition to being operated by Taiyang Company, these refineries are also privately operated. The cave room, also known as the

What are the chemical and physical separation methods used

Physical separation usually involves the difference in mass between gold and most of the other associated minerals. Once the gold is physically separated from the host material and of a relatively similar size it can be separated using a rotary bo...

The methods mentioned so far are all physical separation methods. Sometimes they are sufficient to separate minerals for use, like coal or iron ore. But more often the element that we are looking for is found as a chemical compound, and so will have to be separated by further chemical reactions. For example, copper in Cu 2 S or aluminium in Al

About Platinum

Irrespective of the chemical separation processes used, the platinum metals are recovered in a finely divided metallic powder form. They can be converted to massive metal form by electron-beam melting. The lower-melting-point metals palladium and platinum can be fused by induction melting techniques.

7.6: Classifying Separation Techniques Chemistry LibreTexts

Aug 10, 2020 Distillation, sublimation, and recrystallization use a change in physical state to effect a separation. Chemical reactivity also is a useful tool for separating analytes and interferents. For example, we can separate SiO 2 from a sample by reacting it with HF to form SiF 4. Because SiF 4 is volatile, it is easy to remove by evaporation. If we

Methods for Separating Mixtures Chemistry for Non-Majors

Filtration. Filtration is a separation method used to separate out pure substances in mixtures comprised of particles some of which are large enough in size to be captured with a porous material.Particle size can vary considerably, given the type of mixture. For instance, stream water is a mixture that contains naturally occurring biological organisms like bacteria, viruses, and protozoans.
