  • plate tectonics

    plate tectonics from the late latin: tectonicus, from the ancient greek: τεκτονικός, lit. 'pertaining to building' is a scientific theory describing the large-scale motion of seven large plates and the movements of a larger number of smaller plates of the earth's lithosphere, since tectonic processes began on earth between 3.3 and 3.5 billion years ago.

  • supercritical fluid extraction

    supercritical fluid extraction sfe is the process of separating one component the extractant from another the matrix using supercritical fluids as the extracting solvent.extraction is usually from a solid matrix, but can also be from liquids.sfe can be used as a sample preparation step for analytical purposes, or on a larger scale to either strip unwanted material from a product e.g .

  • xylem inc.

    xylem inc. is a large american water technology provider, enabling customers worldwide to transport, treat, test and efficiently use water in public utility, residential, commercial, agricultural and industrial settings. the company does business in more than 150 countries. launched in 2011 as the spinoff of the water-related businesses of

  • tin mining

    tin mining began early in the bronze age, as bronze is a copper-tin alloy. tin is a relatively rare element in the earth’s crust, with approximately 2 ppm parts per million , compared to iron with 50,000 ppm.

  • monazite

    monazite is a reddish-brown phosphate mineral containing rare-earth metals.to be more specific, it represents a group of minerals. the most common species of the group is monazite- ce , that is, the cerium-dominant member of the group. it occurs usually in small isolated crystals.it has a hardness of 5.0 to 5.5 on the mohs scale of mineral hardness and is relatively dense, about 4.6 to 5.7 g/cm 3.

  • separation process

    complete and incomplete separation. in some cases, separations require total purification, as in the electrolysis refining of bauxite ore for aluminum metal, but a good example of an incomplete separation technique is oil refining. crude oil occurs naturally as a mixture of various hydrocarbons and impurities.

  • thin-layer chromatography

    thin-layer chromatography tlc is a chromatography technique used to separate non-volatile mixtures. thin-layer chromatography is performed on a sheet of glass, plastic, or aluminium foil, which is coated with a thin layer of adsorbent material, usually silica gel, aluminium oxide alumina , or cellulose.this layer of adsorbent is known as the stationary phase.

  • mining

    processing of placer ore material consists of gravity-dependent methods of separation, such as sluice boxes. only minor shaking or washing may be necessary to disaggregate unclump the sands or gravels before processing.
