    but a brain cell doesn't attach in a standard way and then function. it derives it's function from how it is attached. so it can't just be replaced. a new brain cell could only take the place of a dead one if it were to go through the exact same learning experience, which will of course never happen. so the specific memory aspect can't be .

  • gold cyanidation

    despite being used in 90% of gold production: gold cyanidation is controversial due to the toxic nature of cyanide. although aqueous solutions of cyanide degrade rapidly in sunlight, the less-toxic products, such as cyanates and thiocyanates, may persist for some years.

  • assay

    an assay is an investigative analytic procedure in laboratory medicine, pharmacology, environmental biology and molecular biology for qualitatively assessing or quantitatively measuring the presence, amount, or functional activity of a target entity the analyte . the analyte can be a drug, biochemical substance, or cell in an organism or organic sample.

  • pyrite

    unit cell: a = 5.417 å, z = 4 . an example of acid rock drainage caused by pyrite is the 2015 gold king mine waste water spill. dust explosions. pyrite oxidation is sufficiently exothermic that underground coal mines in high-sulfur coal seams have occasionally had serious problems with spontaneous combustion in the mined-out areas of the mine. the solution is to hermetically seal the mined .

  • copper extraction

    supergene ores rich in sulfides may be concentrated using froth flotation. a typical concentrate of chalcocite can grade between 37% and 40% copper in sulfide, making them relatively cheap to smelt compared to chalcopyrite concentrates.

    unit cell: a = 5.417 . an example of acid rock drainage caused by pyrite is the 2015 gold king mine waste water spill. . high-sulfur coal seams have occasionally had serious problems with spontaneous combustion in the mined-out areas of the mine. the solution is to hermetically seal the mined-out areas to exclude oxygen.

  • talk:fluorine/text only

    fluorite mining the main source of fluorine was estimated in 2003 to be a $550 million industry, extracting 4.5 million tons per year. most ores must be processed to concentrate the fluorite from other minerals by various methods of flotation separation. however, only about 1% of mined fluorite is ever converted to elemental fluorine.
