Separation and Purification Process
Separation and Purification Process. Separation and purification processes based on the adsorption technique are also important in nuclear waste and the nuclear industry, where activated carbon is often used for the separation of metal ions from solutions due to its selective adsorption, high radiation stability, and high purity [125].

Mineral processing
This separation technique can be useful in mining iron as it is attracted to a magnet. In mines where wolframite was mixed with cassiterite , such as South Crofty and East Pool mine in Cornwall or with bismuth such as at the Shepherd and Murphy mine in Moina, Tasmania, magnetic separation was used to separate the ores.

Electrostatic Separation
Magnetic, electrostatic, and density separation are mechanical separation techniques that have been widely used in urban mining of WEEE. Low-intensity drum separators are the standard method of magnetic separation for the recovery of ferromagnetic metals from nonferrous metals and other nonmagnetic wastes ( Hsu et al., 2019 ).

Rare Earth Elements
Refinement occurs through physical separation of the REEs by various chemical techniques, sometimes involving thousands of steps. Unfortunately, all REEs and their respective ores are different and require different chemical techniques for refining (depending on melting point and vapor pressure, as well as other physical properties of the element).

The physical and physico-chemical separation techniques are needed to concentrate those products for recycling in a good way. According to physical and physico-chemical properties of different products present in urban mine, the physical separation techniques permit to separate or isolate them, for re-use or appropriate treatment or disposal.

Methods for Separating Mixtures | Chemistry for Non-Majors
Evaporation is a technique used to separate out homogenous mixtures where there is one or more dissolved solids. This method drives off the liquid components from the solid components. The process typically involves heating the mixture until no more liquid remains, Prior to using this method, the mixture should only contain one liquid component, unless it is not important to isolate the liquid

Sink and Float Separation Process
Evaluation of products by separating into sink and float fractions. Sink-Float Tests are classed as bulk or selective separations. A bulk test gives two products, first, the lighter minerals with a gravity less than 2.8 to 3.3 and, second, minerals having a gravity heavier than 2.8 to 3.3. The separation depends on the gravity of the media used.

Gold Mining Methods
Placer mining takes a variety of forms, including panning, "sluice-boxing", hydraulic mining, and dredging. All of these techniques use gravity and water to separate the dense gold from the lighter sand and gravel. Some modern commercial placer operations are quite large and utilize heavy equipment and river diversions.

These separation techniques rely on the differences in size of the particles of the substances that make up the mixture. The effectiveness of separating a mixture by filtering (or sieving or straining) depends on the size of the holes in the filter (or sieve or strainer) compared to the size of the particles being separated.
