How To Identify Gold Ore From Copper Ore

Ore is rock that contains economic amounts of a particular element, e.g. gold ore, iron ore, molybdenum ore, or praseodimium ore. In contrast, rock that is not judged to contain economic quantities of an element is categorized as waste rock. The metals in ore can occur in many different minerals (compounds) in the rock. As an example, copper occurs in more than 50 minerals

Copper: Copper is a very easy mineral to test for. First crush the ore and dissolve it in nitric acid by heating. Then dilute with some water, and add ammonia. The solution should turn dark blue. The carbonate ores of copper do not extend deep in the mine. Their places are taken by copper pyrites. Sulfide ores are usually difficult to treat, and when they are to be tested it is better to roast ...
