Copper is found in natural ore deposits around the world. The most abundant ore are chalcopyrite and bornite, which contain both copper and iron sulphides. These account for about 80% of the worlds known ores. We supply ores with copper content within fairly narrow ranges of specifications to satisfy our customer needs
The main copper sulphide minerals are chalcopyrite (CuFeS2) chalcocite (Cu2S), covellite (CuS), bornite (Cu5FeS4), tetrahedrite ((Cu,Fe)12Sb4S13) and enargite (Cu3AsS4). The largest source of copper is from porphyry ore deposits in which one or a combination of the minerals occurs. A typical copper sulphide ore contains various levels of iron sulphide types that generally include pyrite (FeS2) and pyrrhotite (Fe1-xS). Often gold and silver are present which may either be associated with the sulphides or are free. The gangue particles can consist of a range of silicate minerals from quartz to talc and clays.

Copper ore is a naturally occurring mineral rock that contains copper in varying concentrations. It's extracted from the earth through mining and then processed to produce copper concentrate, which is further refined to produce pure copper.
## Types of Copper Ore
1. Sulfide ores: These ores contain copper in the form of sulfide minerals, such as chalcopyrite (CuFeS2), bornite (Cu5FeS4), and chalcocite (Cu2S).
2. Oxide ores: These ores contain copper in the form of oxide minerals, such as cuprite (Cu2O), tenorite (CuO), and malachite (Cu2CO3(OH)2).
3. Native copper: This type of ore contains copper in its native form, often found in quartz veins or other igneous rocks.
## Copper Ore Deposits
1. Porphpyry copper deposits: These deposits are formed through magmatic-hydrothermal processes and are characterized by large, low-grade copper deposits.
2. Volcanogenic massive sulfide (VMS) deposits: These deposits are formed through volcanic activity and are characterized by high-grade copper deposits.
3. Sedimentary copper deposits: These deposits are formed through sedimentary processes and are characterized by low-grade copper deposits.
## Major Copper-Producing Countries
1. Chile: The world's largest copper producer, accounting for approximately 30% of global production.
2. Peru: The second-largest copper producer in South America.
3. Australia: A significant copper producer, with major mines in Western Australia.
4. United States: Copper is mined in several states, including Arizona, Utah, and Montana.
5. China: A major copper producer and consumer, with significant mining and smelting operations.
Uses of Copper Ore
1. Copper production: Copper ore is processed to produce copper concentrate, which is then refined to produce pure copper.
2. Electrical applications: Copper is an excellent conductor of electricity, making it a crucial material for electrical wiring, circuits, and electronic devices.
3. Construction and architecture: Copper is used in building construction, including roofing, plumbing, and electrical systems.
4. Industrial machinery and equipment: Copper is used in the production of various industrial machinery and equipment, including motors, generators, and transformers.
