Two 2 major techniques for refining gold. Generally, gold can be refined using these two-best-known gold-refining procedures Aqua Regia and gold electrolysis. Both of these techniques can be used to separate gold from other metals. This is because a little piece of other metals in gold can change its properties and value.
Jul 09, 2019 Ghanas quest to have 30 per cent of its gold locally processed is on course as Gold Coast Refinery Limited in Accra, continues to add value to gold, three years after its setup.
