Process simulation and gate-to-gate life cycle assessment

Halogen leaching. Chlorine has been known to leach gold from ores and concentrates since the 1800s (Rose 1898). A process using halogens recycled as hypochlorites for gold leaching from refractory gold ores has been patented recently (Lalancette et al. 2015a). This process was chosen for comparison as it is one of the closest to

Electrowinning - Wikipedia

Electrowinning, also called electroextraction, is the electrodeposition of metals from their ores that have been put in solution via a process commonly referred to as leaching. Electrorefining uses a similar process to remove impurities from a metal. Both processes use electroplating on a large scale and are important techniques for the economical and straightforward purification of non-ferrous metals. The

Can Gold be Extracted from Seawater? (with pictures

1/20/  · @anon278951-- T-6 is a chemical solution that people use to leach gold and other metals. I think it's just sodium polythiocarbonate. Lots of people seem to be using it but it seems kind of dangerous to use. It certainly requires experience with chemicals and leaching. It's also quite expensive.

recovery of gold from ores with chlorine in 1898 - Page 1

Thinking over what you said, I looked again at one of the 1890's recipes for making a gold leaching chlorine solution. In this case, chlorine gas was introduced into a cylinder containing ground ore and water. Following, compressed air was introduced to a pressure of 60 psi, dissolving Cl2 gas in the water. Once dissolved, the following happened:
