The production of minerals involves a series of physical and chemical processes These may occur at any time from excavation of the ore that contains the metal in mineral form through production of the metal in marketable form Methods for physically separating the ore from surrounding material also include complex processes such as leaching mixing the ore with chemical solutions or other

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

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 le 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

Separation Techniques Physical separation techniques are based on the physical properties of the substance These physical properties can be physical state magnetic and electrical properties specific gravity density melting point boiling point and solubility Here are some different methods of separating mixtures 1 Solubility

Beginning in the late 1840s thousands of prospectors rushed to California to search for gold One of the approaches taken to isolate the gold from the soil was called “panning” Dirt would be placed in the pan and covered with water After thorough mixing the pan is gently swirled to remove dissolved material while the heavier gold settles to the bottom of the pan
