Rand refinery - Refinement towards perfection

Since its establishment in 1920, Rand Refinery (close to Johannesburg, South Africa) has refined nearly 50,000 tons of gold – almost one third of all the gold mined worldwide. Also silver is refined to the same high benchmark standards. The refinement process starts at the smelter, which currently processes over 70 different types of material, including by-products from the mining industry, electronic waste, carbon fines and sludge. Here, all low-grade materials are concentrated into a semi-pure product that is further refined into the pure elements at the main refinery.
