    How can metal mining impact the environment? American

    Tailings produced from the milling of sulfide ores primarily copper, lead, and zinc ores may have concentrations of pyrite that are greater than those common in waste rock. Also, because tailings are composed of small mineral particles the size of fine sand and smaller, they can react with air and water more readily than waste rocks.

    purification of copper by electrolysis metal extraction

    Copper can be extracted from copperrich ores by heating the ores in a furnace (smelting) and the copper can be purified by electrolysis. However, the supply of copperrich (high grade) ores is limited. Copper is extracted from its ores by chemical processes that involve heat or electricity (roasting ores in a smelterfurnace and

    Malachite is a copper ore consisting mainly of basic copper(II) carbonate, CuCO 3.Cu(OH) 2. This experiment involves producing copper from copper(II) carbonate. The copper carbonate is first heated to produce copper(II) oxide, which is then reduced to the metal using carbon as a reducing agent.
