Gold Mining Operation: 10 30 years. The gold mining operation stage represents the productive life of a gold mine, during which ore is extracted and processed into gold. Processing gold involves transforming rock and ore into a metallic alloy of substantial purity – known as doré – typically containing between 6090% gold.

gold processing, preparation of the ore for use in various products. For thousands of years the word gold has connoted something of beauty or value. These images are derived from two properties of gold, its colour and its chemical stability. The colour of gold is due to the electronic structure of the gold atom, which absorbs electromagnetic radiation with wavelengths less .

Thus, the bulk of the gold may be recovered by leaching techniques using cyanidation or aqueous chlorination, and the residue may then be treated by smelting to recover the balance. Generally, scrap with a gold content of less than percent, unless readily recoverable by leaching, is recycled back to a pyrometallurgical process.

5 Simple Methods to Test Gold Dusts 1. Sunlight Method Take a few sample of the gold dusts that you recovered and expose it under the sunlight. An authentic gold will "shine"but it will not "sparkle". If the particles sparkled under sunlight, it means that you have found pyrites (also known as "Fool's Gold"). 2. Magnet Method
