    The flow diagram below shows how the percentage of copper increases as the ore is refined, first physically by froth flotation, then chemically by smelting and finally electrolytic refining. The smelting stage gives the name pyroprocessing: processing by fire. (Courtesy of Xstrata.) The smelter for sulfide ores produces sulfur dioxide gas. This is scrubbed from the flue gases to make sulfuric ...

    Gold grades tend to be higher than in quartzsulphide gold + copper and poylmetallic goldsilver vein systems, no doubt due to the more efficient mechanism of metal deposition provided by mixing the ore fluid with bicarbonate waters (Corbett and Leach, 1998). Localised high to bonanza gold grades within carbonatebase metal gold deposits are attributed to a number of factors including:

    Sulfur Intake in Cattle

    Copper bioavailability is decreased by high dietary sulfur concentrations. This is probably due to the formation of copper sulfide and/or the thiomolybdatecopper complex. High sulfur intake conditions can result in conditions that lead to destruction of thiamin. Although severe thiamin deficiency states have not been demonstrated under high sulfur intake conditions, moderate thiamin deficits ...
