Chalcopyrite is an accessory mineral in Kambalda type komatiitic nickel ore deposits, formed from an immiscible sulfide liquid in sulfide-saturated ultramafic lavas. In this environment chalcopyrite is formed by a sulfide liquid stripping copper from an immiscible silicate liquid.

Chalcopyrite is one of the minerals refered to as "Fool's Gold" because of its bright golden color. But real gold is a more buttery yellow and is ductile and malleable. As an ore od copper, the yield of chalcopyrite is rather low in terms of atoms per molecule.
This "secondary enrichment" occurred when pyrite (iron sulfide) oxidized, dissolved in rainwater, and formed an acidic iron sulfate solution that dissolved the main copper-ore mineral, chalcopyrite (copper-iron sulfide). The dissolved copper was redeposited, principally as the mineral chalcocite (copper sulfide).
The proportion of iron is 100 — (34.8 + 34.8) = 30.4%. Roughly, the ore may be considered as composed of one-third each of copper, sulphur, and iron. This is the commonest ore of copper; but its value depends so much on circumstances other than the percentage of copper contained in it that it is not quoted on the market.

Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.
An ore deposit is an accumulation of ore. This is distinct from a mineral resource as defined by the mineral resource classification criteria.
Metals & Minerals We produce and market a diverse range of metals and minerals – such as copper, cobalt, zinc, nickel and ferroalloys - and also market aluminium/alumina and iron ore from third parties.
Bornite is an important copper ore mineral. It ranks up there with many of the other copper ores such as chalcocite, chalcopyrite, covellite, digenite, cuprite and tetrahedrite.As a mineral specimen, bornite is usually lacking.
Mining and mineral processing We have hands-on experience with all types of ore bodies and mineralogy. Our work covers the entire iron-ore value chain, from mining through to crushing, grinding, and beneficiation by gravity, magnetic, or heavy media separation.

Copper - Most copper ore bodies are mined from minerals created by weathering of the primary copper ore mineral chalcopyrite. Minerals in the enriched zone include chalcocite, bornite, djurleite. Minerals in the oxidized zones include malachite, azurite, chyrsocolla, cuprite, tenorite, native copper …
Iron is a common element in many minerals. The minerals goethite, hematite (ferric oxide), lepidocrocite, magnetite (iron oxide) and siderite (iron carbonate) are all mined for iron. The largest concentrations are in iron-rich sedimentary rocks, and such deposits are mined in Russia, Brazil, China, Australia, India and the USA.
Collectable Copper Ores and Minerals. This is a selection of the most commonly collected copper ores. Also included are a few other interesting ores of metals often alloyed with copper such as zinc, lead and bismuth.
An oversupply of iron ore combined with China adding more steel-making capacity than it needed, resulted in a slump in the iron ore spot prices over the past two years, including a staggering 47% ...
For global mineral and material commodities data, see Data Series 896. General Notes. The U.S. Geological Survey (USGS) provides information to the public and to policy-makers concerning the current use and flow of minerals and materials in the United States economy.
Bornite is a copper iron sulfide mineral with a chemical composition of Cu 5 FeS 4. It occurs in igneous, metamorphic, and sedimentary rocks. Minable concentrations of bornite occur in hydrothermal veins, contact metamorphic zones, and in the enriched zone of many sulfide mineral …
Copper - Mineral Fact Sheets - Australian Mines Atlas. The main ore mineral of copper in Australia (and worldwide) is chalcopyrite which is a mixture mainly of iron and copper …
Ore: Ore, a natural aggregation of one or more minerals that can be mined, processed, and sold at a profit. An older definition restricted usage of the word ore to metallic mineral deposits, but the term has expanded in some instances to include nonmetallics. Although more than 2,800 mineral species

The largest source of copper is from porphyry ore deposits in which one or a combination of the aforementioned minerals occurs. A typical copper sulphide ore contains various levels of iron sulphide types that generally include pyrite (FeS2) and pyrrhotite (Fe1-xS).
An ore is an occurrence of rock or sediment that contains sufficient minerals with economically important elements, typically metals, that can be economically extracted from the deposit. The ores are extracted from the earth through mining; they are then refined (often via smelting) to extract the valuable element, or elements.. The grade or concentration of an ore mineral, or metal, as well ...
