components of a gold ore

    Gold (Au)

    Gold electroplating is used to in the electronic industry to protect their copper components and improve their solderability. Gold in the environment Gold is widely distributes on the earth at a background level of 0.03 g/1000 kg (0.03 ppm by weight). · Gold ore can resemble quartz with spotty areas of gold. According to the Environmental Protection Agency, gold is commonly mixed (alloyed) with silver and other metals. The ore may, therefore, contain sulfides like arsenic, copper, iron, and silver. The ore does not commonly have visible shiny gold on the surface.Read more

    Because of gold's inertness some 80% of gold within ore is in its elemental state. There are several processes used in gold mining for extracting, and then purifying it. Amalgamation is a mercury based process which works because of gold's willingness to be dissolved by mercury.Gold panning is mostly a manual technique of separating gold from other materials. Wide, shallow pans are filled with sand and gravel that may contain gold. The pan is submerged in water and shaken, sorting the gold from the gravel and other material. As goldRead more

    Iron ores generally have higher grades than sulphide or gold ores, often going over 50 per cent or more. Less tailings are therefore generally produced in iron ore projects. After separating the valuable minerals, the tailings are often pumped in a slurry through pipes to be deposited in a tailings storage facility (TSF) (also called tailings management facility, TMF).Poul Emsbo, Albert H.
