A Poor Man's Method of Smelting Gold Sciencing

2018-05-22  Smelting gold usually involves high-tech and high-cost tools to perform. Mostly, mining companies do the procedure, which sees one material bonded to or released from another in the presence of extreme heat. However, prospectors, and people at home, can smelt their old gold using some simple steps. All it requires is access to a few common minerals and compounds, and a high
