Ore minerals

Manganese - The primary ores are oxides/hydroxides of manganese which include minerals such as hausmannite pyrolusite braunite manganite etc and the carbonate rhodochrosite A large potential source is the deep sea manganese nodules Mercury - The main ore is the sulfide cinnabar Molybdenum - The primary ore mineral is molybdenite

Raw Materials The most common are known as sulfide ores in which the copper is chemically bonded with sulfur Others are known as oxide ores carbonate ores or mixed ores depending on the chemicals present Many copper ores also contain significant quantities of

GCSE CHEMISTRY

Extraction of Metals Extraction of Copper Copper is sometimes found as native metal Copper ores include copper(II) oxide and copper(II) sulfide Copper(II) oxide can be reduced by reaction with carbon Some copper ores may contain only small amounts of copper These are called low grade ores and have less than 1% copper but they are still used because copper is so valuable

Copper extraction

Copper extraction As in all mining operations the ore must usually be beneficiated (concentrated) The processing techniques depend on the nature of the ore If the ore is primarily sulfide copper minerals (such as chalcopyrite ) the ore is crushed and ground to liberate the valuable minerals from the waste ('gangue') minerals

TENORM: Copper Mining and Production Wastes

Copper is used in many different industries including building construction transportation electronics and consumer goods Minerals are concentrated in specific types of geologic formations (ore bodies) which are where mining takes place These ore bodies may already contain naturally-occurring radioactive materials (NORM)

Copper Ore Processing Methods

The four major steps in the production of marketable copper are mining concentrating smelting and refining In a few instances however leaching takes the place of concentrating smelting and refining At present although considerable leaching and direct-smelting ores are produced the bulk of the copper ore mined is concentrated The milling of copper ores as practiced in the larger

History of Copper

Copper extracted from ore classed as copper bearing (copper copper-lead and copper-zinc ores) and total production of copper from all sources in 1915 Considerable copper was recovered from old slag and ores not classed as copper ores Most of the copper from Colorado is derived from ores classed as siliceous ores and lead ore

Copper Ores

Copper Ores The copper-pyrite ores play an important role accounting for more than 5 percent of the world's known copper reserves (excluding the socialist countries) Such deposits are located in the USSR (Urals) Spain (Riotinto) Yugoslavia (Bor) Turkey (Ergani-Maden) and other countries

Zinc ore and mines

Its chief use was to make brass by mixing with copper Primary zinc veins The primary zinc ore sphalerite is typically found in thin veins cutting through the rock In these veins the ore occurs as either thin layers encrusting on the walls of the vein or as thin bands pockets or crystals within the vein

copper extraction and purification

Extracting copper from other ores Copper can be extracted from non-sulphide ores by a different process involving three separate stages: Reaction of the ore (over quite a long time and on a huge scale) with a dilute acid such as dilute sulphuric acid to produce a very dilute copper(II) sulphate solution

Copper Facts: Chemical and Physical Properties

It is found in many minerals including malachite cuprite bornite azurite and chalcopyrite Copper ore deposits are known in North America South America and Africa Copper is obtained by smelting leaching and electrolysis of the copper sulfides oxides and carbonates Copper is commercially available at a purity of 99 999+ %

What Are the Properties and Uses of Copper?

In humans copper is typically found in the liver muscles and bones with a value of 1 4mg and 2 1mg of copper per kilogram of weight being within normal parameters History of Copper The name of this metal comes from the Old English 'coper' which in turn derives from the Latin 'Cyprium aes' which means 'metal from Cyprus'
