use of pyrometallurgy and hydrometallurgy in gold ore processing

23.3: Metallurgy - Chemistry LibreTexts

A metal is separated from its ore and then isolated by using pyrometallurgy or hydrometallurgy or by taking advantage of unusual chemical or physical properties of a particular compound. The conversion of metals from their ores to more useful forms is called metallurgy, which consists of three general steps: mining, separation and …

Hydrometallurgy | Request PDF

Hydrometallurgy is a relatively recent development compared with pyrometallurgy—the ancient art of metal production. People learned thousands of years ago to build furnaces and use fire to melt rocks and produce metals. Use of water and aqueous solutions in place of dry, high-temperature methods for processing ores came much later.

on a refractory gold concentrate. The SO 2 and As 2 O 3 gases were fixed based on the following reactions below: 2CaO (s) + 2SO 2 (g) + O 2 (g) → 2aSO 4 (s) 3CaO (s) + As 2 O 3 (g) + O 2 (g) → a 3 (AsO 4) 2 (s) The free energy estimation for the reactions showed Ca 3 (AsO 4) 2 is thermodynamically more stable than CaSO 4.
