  • retort

    in a chemistry laboratory, a retort is a device used for distillation or dry distillation of substances. it consists of a spherical vessel with a long downward-pointing neck. the liquid to be distilled is placed in the vessel and heated. the neck acts as a condenser, allowing the vapors to condense and flow along the neck to a collection vessel placed underneath.

  • weyburn-midale carbon dioxide project

    at the plant, co 2 is produced from a rectisol unit in the gas cleanup train. the co 2 project adds about $30 million of gross revenue to the gasification plant's cash flow each year. approximately 8000 tonnes/day of compressed co 2 in liquid form is provided to the weyburn and midale fields via the pipeline.

  • carbon in pulp

    carbon in pulp cip is an extraction technique for recovery of gold which has been liberated into a cyanide solution as part of the gold cyanidation process. 1 introduced in the early 1980s, carbon in pulp is regarded as a simple and cheap process.

  • gold mining

    the pan is submerged in water and shaken, sorting the gold from the gravel and other material. as gold is much denser than rock, it quickly settles to the bottom of the pan. the panning material is usually removed from stream beds, often at the inside turn in the stream, or from the bedrock shelf of the stream,.

  • gold mining

    placer mining is the technique by which gold that has accumulated in a placer deposit is extracted. placer deposits are composed of relatively loose material that makes tunneling difficult, and so most means of extracting it involve the use of water or dredging. panning

  • catalytic reforming

    catalytic reforming is a chemical process used to convert petroleum refinery naphthas distilled from crude oil typically having low octane ratings into high-octane liquid products called reformates, which are seven trust blending stocks for high-octane gasoline.the process converts low-octane linear hydrocarbons paraffins into branched alkanes isoparaffins and cyclic naphthenes, which are .

  • respiration physiology

    in physiology, respiration is the movement of oxygen from the outside environment to the cells within tissues, and the transport of carbon dioxide in the opposite direction.. the physiological definition of respiration differs from the biochemical definition, which refers to a metabolic process by which an organism obtains energy in the form of atp and nadph by oxidising nutrients and .

  • hydraulic mining

    hydraulic mining is a form of mining that uses high-pressure jets of water to dislodge rock material or move sediment. in the placer mining of gold or tin, the resulting water-sediment slurry is directed through sluice boxes to remove the gold. it is also used in mining kaolin and coal. hydraulic mining developed from ancient roman techniques that used water to excavate soft underground deposits. its modern form, using pressurized water jets produced by a nozzle called a 'monitor', came about in

  • placer mining

    placer mining is frequently used for precious metal deposits particularly gold and gemstones, both of which are often found in alluvial deposits—deposits of sand and gravel in modern or ancient stream beds, or occasionally glacial deposits. the metal or gemstones, having been moved by stream flow from an original source such as a vein, are typically only a minuscule portion of the total deposit.
