Miners used chemicals, heat, and electricity to process more complex metal and mineral compounds. Silver, for example, often occurs in the compound argentite (silver sulfide) or in lead compounds. Historically, the key chemical processes included amalgamation with mercury and leaching in a solution of chlorine, sodium or calcium hyposulfite (lixiviation), or cyanide.

An ore is an item (usually a type of unrefined metal) that can be mined from rocks or mineral veins using the Mining skill and a Pickaxe. Items such as gems, clay, granite, and essences are not ores per se, however they are still discussed on this page as they can be obtained via Mining. Metal ores can be smelt into bars using the Smithing skill. Trivia The heaviest ore is Lunar ore, and the
Its hard to extract the metal values out of sulfide ores. Here are some thoughts on using smelting (melting the sulfides) or roasting (rapid oxidation using heat) to recover those gold and silver values. Geology of Gold Deposits Ever wonder where all that Here is

Nickel: smelting Extraction and purification Nickel is recovered through extractive metallurgy: it is extracted from its ores by conventional roasting and reduction processes that yield a metal of greater than 75% purity. In many stainless steel applications, 75% pure nickel can be used without further purification, depending on the composition of the impurities.
Metal from Ore Ores are rocks or minerals from which a valuable substance – usually metal – can be extracted. Some common ores include galena (lead ore), bornite and malachite (copper), cinnabar (mercury), and bauxite (aluminum).
These rocks filled with metal are called ores, and they're mined out to be used for all kinds of items. Metals have special properties, including being malleable, which means they can be easily

Infographic: History of Metals Timeline The development of civilisation has relied heavily on the discovery of metals. Prehistoric man used metals to build tools and weapons and as our knowledge of metallurgy has developed, metals have played an essential role in the advancement of agriculture, transport and arts and craft – forging the path to today's modern society.

Methods of extraction Many metals are found in the Earth's crust as ores. An ore is usually a compound of the metal mixed with impurities. When the metal is dug up, a method must be used to separate the metal from the rest of the ore. This is called extracting the
Examples of Metal Ores. The term ore is used to refer to a rock that contains minerals such as metals. In general, ores are oxides, sulfides, silicates or "native metals," those found in nature. Oxides and sulfides are called such because the minerals contain oxygen

The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as chalcopyrite ((CuFeS 2)) are converted to copper by a different method from silicate, carbonate or sulfate ores.
Copper is one of the first metals to be used, largely because it occurs in metallic form at the surface. By 4000 B.C., it was being smelted from ores in Israel and other parts of the Middle East. Copper is a malleable, ductile reddish metal, and is one of only two strongly colored metals (gold being the other).
