  • Selective separation of gold from iron ore samples using

    Selective Separation Of Gold From Iron Ore Samples Using

    Abstract. Gold in iron ore samples is separated from iron (major matrix cation), antimony and vanadium using anion exchange resin in (0.2 M) HBr, potassium peroxodisulfate and acetonewaternitric acid media. The exchangeable anion Cl of the ion exchanger Dowex 1X 4 is replaced by Br using (6 M) HBr solution.

  • Extracting Gold HowStuffWorks

    Extracting Gold Howstuffworks

    Leaching dissolves the gold out of the ore using a chemical solvent. The most common solvent is cyanide, which must be combined with oxygen in a process known as carbon-in-pulp. As the cyanide and oxygen react chemically, gold in the pulp dissolves. When workers introduce small carbon grains to the tank, the gold adheres to the carbon.

    Extracting A Metal From Its Ore

    Metals with low chemical activity, such a gold and silver are normally found in their pure state. Copper, tin, lead, and iron are more reactive and must be heated with carbon to extract the metals. Aluminum, calcium, sodium and other active metals are extracted using electrolysis. Copper can be extracted from its ores by reduction.

    The two of the best known processes are smelting and roasting. The two are actually different methods, but both involve heating the ore to high temperatures. Technically, any methods which consist of processing ore by heating it are called pyrometallurgy. The old timers took advantage of the chemical instability of sulfides by simply heating (or roasting) them to burn off the sulfur.

    The process works best when the ore is crushed to small pieces before roasting. Additives, such as common rock salt are often added to the mix before it is heated to enhance the reaction of the sulfides. Once the ores are fully roasted, and the sulfur is driven off, the extraction of the gold or silver from the ore is not especially difficult.
