Separating the Platinum Group Metals by Liquid–Liquid

To extract the platinum group metals from the ore, and to refine them to the very high purity required for their many applications, requires a multitude of complex operations. At present the final refining stage that produces the individual platinum group metals is carried out by selective precipitation from a solution of mixed platinum group metals, but this is inefficient as far as the

Occurrence of Metals: Metal Ores, Methods of Extraction

Metallurgy is the process of extracting metals. The basic step of extracting metals is called concentration of ores. Concentration of Ores. The ores contain a lot of impurities that need to be filtered. The filtration of these impurities from ores is known as concentration. Concentration can be done by gravity separation or hydraulic washings

Methods Of Physical Separation Separating Mixtures

Chapter overview. 2 weeks 'Mixtures' was first introduced in Gr. 6, so learners should already be familiar with these concepts. Learners would have also looked at some of the physical methods of separating different types of mixtures (including hand sorting, sieving, filtration), and this year we will explore some additional methods in more detail (including distillation and chromatography).

IGCSE Extraction of Metals From Ores Notes IGCSE And IAL

Extraction of Metals. Industries extract metals from their ores. What are ores? Let me explain in a simple way. Usually, less reactive metals such as gold and silver are found in their pure form in the soil. But this is not the case with more reactive iron or aluminum. Usually iron and aluminum exist as compounds, with oxygen, also known as oxides.

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.
