    Chlorine is a strong oxidizing element causing the hydrogen to split from water in moist tissue, resulting in nascent oxygen and hydrogen chloride that cause corrosive tissue damage. Additionally oxidation of chlorine may form hypochlorous acid, which can penetrate cells and react with cytoplasmic proteins destroying cell structure.

    An acidic solution — generally hydrochloric acid — is used to separate the gold from the carbon. The gold-laden liquid is poured over electrified steel, which attracts flakes of the metal. Heavy metals are a byproduct of refinement. In 2000, a cask of mercury leaked in transit from the Yanacocha mine, sickening nearly 1,000 people.
