Gold refining. This refers to processes used to processes used to extract and separate the precious metals in mined material, dor, and from recycled products (jewellery and electronics). The main techniques used to remove the final impurities to create high caratage gold are summarised below REFINING TECHNIQUE. REMOVES BASE METALS.
Mar 18, 2021 Gravel deposits account for more than 80% of global tin production. Once miners extract tin ores, they go through a series of chemical filtering steps to obtain increasingly greater concentrations of tin. Filtering. Revolving screens and shakers dredge the gravel and separate the tin ores from sand and other debris.
Extraction of tin consists of three parts, i.e. tin ore concentration, smelting and refining. Cassiterite is the main source of tin ore, with specific gravity of 6.8-7g/cm 3, density larger than most of gangue.Therefore, 90% of tin concentrate is mainly obtained from cassiterite through gravity separation.

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.
