Dangers of gold refining

 Damien Oettli, head of markets at the WWF, is one of the skeptics. He questions the premise that gold could ever become environmentally sound. The way the precious metal is mined and traded today takes a heavy toll on nature and the environment, he says. Extraction takes place in areas with very high biodiversity, and the process pollutes water resources and the air. The processing stages that follow take place across the world. When forests are destroyed for mining, this has a negative impact on the climate as well as biodiversity. Artisanal mining brings the added burden of mercury pollution. https://www.swissinfo.ch/por/empresa-promete-refinar--ouro--ecol%C3%B3gico/47997354?utm_campaign=teaser-in-querylist&utm_source=swissinfoch&utm_medium=display&utm_content=o
