mineral processing gold and iron and separating them

Mineral processing - Wikipedia

Gravity separation is one of the oldest technique in mineral processing but has seen a decline in its use since the introduction of methods like flotation, classification, magnetic separation and leaching. Gravity separation dates back to at least 3000 BC when Egyptians used the technique for separation of gold.

Sulphur Refining of Gold - Mineral Processing Metallurgy

Mar 19, 2017  The matte, as a rule, can be knocked off. If the gold and matte are poured into a mould there is often the greatest difficulty in separating them. A complex matte, consisting as it often does of gold, silver, antimony, copper, and iron sulphides, clings persistently to the gold bar, and is not appreciably attacked by nitre or sulphuric acid.
