Why would extracting copper have a large environmental impact?
网页2020年2月13日 Excess copper in the soil creates a toxic environment for most micro-organisms such as bacteria. Copper toxicity in the soil inhibits mineralization of nutrients such as phosphorus and nitrogen since the metal gets attached to minerals and organic matter. Animals absorb copper when feeding in contaminated ground, leading to poor
