The density of standard gold is, and that of the alloy containing gold 900, copper 100 is For the densities of other goldcopper alloys. Many of the alloys have been used for coinage at various times. The Greeks and Romans, after electrum had fallen into disuse, employed the purest gold they could procure, viz., that from 990 to ...
The Hunt methodcalls for the direct treatment of the ore with a solution of potassium cyanide to which ammonium hydroxide has been added. The gold is thus extracted together with some copper, and the metals are recovered by electrolytic precipitation, the gold, silver and copper falling to the bottom of the vats as a sludge.
Copper (Cu) is a ductile metal that''s an excellent conductor of electricity. For this reason, more than half the world''s copper is used in electrical motors, wiring or anything that requires electricity. Global demand drives the price with emerging markets playing a significant role.

Most copper ores contain only a small percentage of copper metal bound up within valuable ore minerals, with the remainder of the ore being unwanted rock or gangue minerals, typically silicate minerals or oxide minerals for which there is often no value. The average grade of copper ores in the 21st century is below % copper, with a ...
Value difference indicates the difference between the average value of the required bars of metals vs. the value of the resulting bars of alloy what went in vs. what comes out, measured per bar. "+0" indicates that the resulting alloy is a perfectly average value of the component metals. Note that substituting tetredrite for copper ore ...
