Magnesium: extraction; Brife introduction; Magnesium is found in solution in sea-water (about 1.3 kg m-3 magnesium) and in natural brines. It is also found extensively in the ores magnesite (MgCO3) and dolomite (MgCO3.CaCO3). Both of the two types of resources can be used as raw materials to manufacture magnesium metal.

Dissolving Gold and Precipitating Gold Pyrometallurgy

If you want to leach gold you need an oxidizing environment (add chlorine gas or clorox) until you reach an ORP of 1000mV, at a Ph of about 5, hopefully warm temperature and you will leach gold. Once in solution, separate liquid from solids, reduce the ORP to 100 -500 mV using NaHSO3 and your gold …
