The MIT researchers found a promising method of forming liquid copper metal and sulfur gas in their cell from an electrolyte composed of barium sulfide, lanthanum sulfide, and copper sulfide, which yields greater than 99.9 …
Leaching dissolves the gold out of the ore using a chemical solvent. The most common solvent is cyanide, which must be combined with oxygen in a process known as carbon-in-pulp. As the cyanide and oxygen react chemically, gold in the pulp dissolves. When workers introduce small carbon grains to the tank, the gold adheres to the carbon.
Molten copper can be produced from copper (II) oxide by heating with carbon: copper oxide + carbon → copper + carbon dioxide 2CuO (s) + C (s) → 2Cu (l) + CO2(g) Copper (II) oxide is...
