Gold Definition | Copper Metal And Diamonds +27781701667

Gold is a valuable native element. Its composition is Au. It is identified by its gold color, gold streak, and very high specific gravity (19.3). It is used as a monetary standard, in jewelry, and in scientific and medical instruments.

What is Copper….?

Copper is a mineral and an element essential to our everyday lives. It is a major industrial metal because of its high ductility, malleability, thermal and electrical conductivity and resistance to corrosion. It is an essential nutrient in our daily diet. And, its antimicrobial property is becoming increasingly important to the prevention of infection. It ranks third after iron and aluminum in terms of quantities consumed in the AFRICA Copper has been an essential material to man since prehistoric times. In fact, one of the major 'ages' or stages of human history is named after a copper alloy: bronze. Copper was the first metal used by man in any quantity. The earliest workers in copper soon found that it could be easily hammered into sheets and the sheets in turn worked into shapes which became more complex as their skill increased.

Use Of Copper

The Statue of Liberty and other art objects are often made of copper materials because of their durability. Copper and copper alloys are used to transport electricity to and in our homes and businesses. Copper is the primary electrical conductor for appliances and electronics. It is used in durable and decorative applications such as copper roofing, door hardware, railings and decorative trim. It is used in our cars and airplanes and in our plumbing systems. During production of shaped copper materials, various other metals are added to give copper additional properties. These alloying elements add strength, ductility, durability, corrosion protection and other properties.

Native Copper Sample

Copper is an important material for improving our quality of life.Today, modern society demands that data passes between people and organizations in milliseconds. Large diameter submarine copper cables transfer signals between continents, while tiny copper wires transmit power and data to individual users. Even wireless communications require copper cabling in masts and relay stations.From the early days to modern times, copper cables and wire are the unsung heroes of the age of communication, which is a rapidly evolving industry. 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.

Learn About Copper

Copper is man's oldest metal, dating back more than 10,000 years. A copper pendant discovered in what is now in northern Iraq. The Egyptians used the ankh symbol to denote copper in their system of hieroglyphs. It also represented eternal life. Copper axes were manufactured by casting in the Balkans in the 4th millennium BC. The ancient Romans extracted copper ores on Cyprus. The invention of printing in the 15th century increased the demand for copper because of the ease with which copper sheets could be engraved or etched for use as printing plates. At this time copper plates were adopted as the best means of engraving maps. The first known maps printed from copper plates are two Italian editions, dated 1472, by the geographer Claudius Ptolemy.

About Copper and Cobalt in Uganda

Copper has been found at several localities in Uganda but the only significant deposit discovered to-date has been at Kilembe, where copper-cobalt sulphide mineralization occurs. The other areas where copper mineralization has been noted are Bobong in Karamoja region and Kampono and Kitaka in Mbarara district. Copper is also reported in Buhweju, Bushenyi district. Although copper was first reported at Kilembe in 1908, the deposit was not brought into production until 1956 on completion of the railway line to Kasese. Between 1957 and 1979 a total of 16.29 million tons ore averaging 1.95% Cu and 0.18% Co were mined and treated to yield 217,000 tons of blister copper which was exported, plus 1.1 million tons of cobaltiferous pyrite (iron sulphide) which was stockpiled. The Kasese Cobalt Company has installed a 1,000-ton per year cobalt plant and is processing the stockpile of pyrite concentrates

Product Development

Messina Copper restarted operations in 2009. The operational team on site have mobilized a new mining contractor and re-commissioned the concentrator with the assistance of an experienced team of specialist metallurgical and engineering personnel from ZCI. The operational key indicators derived from start up have been encouraging. The feed grade delivered from the pit from fresh ore exposure has been consistently +/-20% above the forecast feed grade of 1.2% Cu. Similarly, the early average concentrate grade produced is 26% Cu which is +/-12% above forecast.
During 2008 work continued on the three main Cu-Zn-Pb-Ag-Au structural corridors identified in the belt and in the Ultramafic Formations with Ni-PGM potential, namely: Thakadu Mutsuku Corridor; Nakalakwana Hill Corridor; Lepashe Cu-Snake Corridor; and the Mosupe-Sebotha Ultramafic Formations. As a result of interpreting the combined historical data of 118,000 soil samples with 17,000 African Copper soil samples, two hundred and seven (207) Cu, Cu-Zn and Cu-Ni first priority Areas of Interest (“AOI’s”) were selected.

Under Botswana legislation, the Company was required to drop 50% of the surface area covered by the Matsitama exploration licences at the end of the first quarter of 2007. The Company applied to the Geological Survey of Botswana to keep approximately 80% of the surface area of the licences on the basis of prospectivity, work-to-date and exploration expenditures over the past two years. Early in the third quarter of 2007, the Geological Survey approved the application to retain most of the ground encompassed by the licences. Of the four licences, 50% of PL 17/2004 was dropped which represented 12% of the total area of 3,528km². Approximately 88% of the ground was retained.
In December 2006, the Government of Botswana granted Messina the Mowana Mining Licence for the area within the Dukwe Project that would contain the surface development and open pit. This approval followed previous approvals by the Government of the EIA and the EMP, the granting of water abstraction rights and the issuance of a conditional archaeological discharge for the site.

African Copper is the holding company of a mineral exploration and development group of companies that are exploring and developing copper deposits in Botswana. The Company is currently commercializing its first copper mine at the Mowana Mine (formerly named the Dukwe Project) and holds permits in exploration properties at the Matsitama Project.
African Copper plc was formerly known as Afrinewco plc and it changed its name to African Copper plc in March 2004. The company was incorporated in February 2004 and is based in London, United Kingdom.
