how to extract gold from copper

  • BBC GCSE Bitesize: Methods of extracting metals

    Copper is easily extracted, but ores rich in copper are becoming more difficult to find. Aluminium and titanium are Methods of extracting metals. The Earth's crust contains metals and metal compounds such as gold, iron oxide and aluminium oxide, but when found in the Earth these are often mixed with other substances.

    A. The amount of gold you will get from 4 tons of circuit boards may not be worth the effort and cost. There are at least two ways to get the gold: (1) cut off the tabs and strip them in cyanide (2) burn the entire collection, smelt the copper and gold out of the ash, then extract the gold from the copper. Both methods are highly
