Extractive metallurgy is the practice of removing valuable metals from an ore and refining the extracted raw metals into a purer form. In order to convert a metal oxide or sulphide to a purer metal, the ore must be reduced physically, chemically, or electrolytically .

Nov 3, 2021However, maraging steel is more expensive than carbon steel, as it is an alloy of iron and non-ferrous metals: nickel (17-19%) cobalt (8-12%) molybdenum (3-5%) titanium (0.2-1.6%) This makes the steel much lighter. For this reason, maraging steel grades are used not only in fencing, but also in the aerospace industry.

Two operations are involved in metallurgical processes. The first one entails separating a metal or metallic compound from a rock material, which usually accompanies the ore. The second one entails refining the extracted metal and producing the metal in its most suitable state. The processes involve mechanical, chemical, and electrical techniques.

Mineralogy is an aspect often overlooked, but it can be very important if dealing with a metallurgically difficult ore or a known refractory ore. By understanding the mineralogical makeup of the gold-bearing and associated species, better-informed decisions can be made with respect to treatment options.
