  • tin iv oxide

    tin iv oxide, also known as stannic oxide, is the inorganic compound with the formula sno 2.the mineral form of sno 2 is called cassiterite, and this is the main ore of tin. with many other names, this oxide of tin is an important material in tin chemistry. it is a colourless, diamagnetic, amphoteric solid.

  • sulfur hexafluoride

    sulfur hexafluoride sf 6 is an inorganic, colorless, odorless, non-flammable, non-toxic but extremely potent greenhouse gas, and an excellent electrical insulator. sf 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. it is a hypervalent molecule.typical for a nonpolar gas, it is poorly soluble in water but quite soluble in nonpolar organic .

  • downstream processing

    downstream processing implies manufacture of a purified product fit for a specific use, generally in marketable quantities, while analytical bioseparation refers to purification for the sole purpose of measuring a component or components of a mixture, and may deal with sample sizes as small as a single cell. stages

  • modelling of particle breakage

    modelling of particle breakage is a process used in grinding.. grinding is an important unit operation used in many industries, such as ceramics, composites, foods, minerals, paints, inks and pharmaceuticals. current technology, however, is inefficient and power-intensive. it is, therefore, important that grinding processes are properly designed and grinding devices are operated at optimum .

  • peak minerals

    peak minerals marks the point in time when the largest production of a mineral will occur in an area, with production declining in subsequent years. while most mineral resources will not be exhausted in the near future, global extraction and production is becoming more challenging. miners have found ways over time to extract deeper and lower grade ores with lower production costs.

  • archaea

    in mineral processing, acidophilic archaea display promise for the extraction of metals from ores, including gold, cobalt and copper. archaea host a new class of potentially useful antibiotics. a few of these archaeocins have been characterized, but hundreds more are believed to exist, especially within haloarchaea and sulfolobus. these .

  • chromium nitride

    chromium nitride is a chemical compound of chromium and nitrogen with the formula crn. it is very hard, and is extremely resistant to corrosion.it is an interstitial compound, with nitrogen atoms occupying the octahedral holes in the chromium lattice: as such, it is not strictly a chromium iii compound nor does it contain nitride ions n 3− .chromium forms a second interstitial nitride .

  • beryllium

    beryllium sulfide, selenide and telluride are known, all having the zincblende structure. beryllium nitride, be 3 n 2 is a high-melting-point compound which is readily hydrolyzed. beryllium azide, ben 6 is known and beryllium phosphide, be 3 p 2 has a similar structure to be 3 n 2.

  • settling

    settling is the process by which particulates settle to the bottom of a liquid and form a sediment.particles that experience a force, either due to gravity or due to centrifugal motion will tend to move in a uniform manner in the direction exerted by that force. for gravity settling, this means that the particles will tend to fall to the bottom of the vessel, forming a slurry at the vessel base.

  • well logging

    well logging, also known as borehole logging is the practice of making a detailed record a well log of the geologic formations penetrated by a borehole.the log may be based either on visual inspection of samples brought to the surface geological logs or on physical measurements made by instruments lowered into the hole geophysical logs .some types of geophysical well logs can be done .
