Copper Ores Metallurgy
BBC - GCSE Bitesize: Metal ores
Metal ores. Most metals must be extracted from rocks, called ores, in the Earth's crust. Ores contain the metal, or a compound of the metal, in a high enough concentration to make it worth extracting the metal. Oxidation and reduction. Oxidation is the gain of oxygen by a substance.
HISTORY OF METALLURGY
The next great development in metallurgy involves a metal which is the most abundant in the earth's surface but which is much more difficult to work than copper or tin. It is iron, with a melting point too high for primitive furnaces to extract it in pure form from its ore.
Smelting - Wikipedia
Smelting is a form of extractive metallurgy; its main use is to produce a base metal from its ore. This includes production of silver, iron, copper and other base metals from their ores. Smelting makes use of heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving just the metal base behind.
Roasting in Metallurgy - Mineral Processing & …
In metallurgy, the operation of roasting, as a preliminary to chlorination, has for its object the expulsion of the sulphur, arsenic, antimony and other volatile substances existing in the ore, and the oxidation of the metals left behind, so as to leave nothing (except metallic gold) which can combine with chlorine when the ore is subsequently treated with it in …

Iron metallurgy developed very slowly, even though iron ores are much more common than copper ores and the temperature for their reduction is lower. The reason for the earlier development of copper metallurgy lay in the significantly lower quality of bloomery iron relative to copper.

Metallurgy probably takes the prize of adding the most ores to Minecraft for any mod for Minecraft. It also adds some OreDictionary ores like Tin and Copper. Also, it supports mods like Tinker's Construct if you download ExtraTic. Metallurgy adds 35 ores, of which 23 in the overworld, 10 in the Nether and 2 in the End.
USGS Minerals Information: Copper
Copper is usually found in nature in association with sulfur. Pure copper metal is generally produced from a multistage process, beginning with the mining and concentrating of low-grade ores containing copper sulfide minerals, and followed by smelting and electrolytic refining to produce a pure copper cathode.

Most of the copper ores mined in the United States contain only about 1.2-1.6% copper by weight. The most common sulfide ore is chalcopyrite, CuFeS 2 , also known as copper pyrite or yellow copper ore. Chalcocite, Cu 2 S, is another sulfide ore. Cuprite, or red copper ore, Cu 2 O, is an oxide ore.
