Copper is a chemical element in the periodic table with the symbol Cu (from the Latin word cuprum, meaning ‘metal of Cyprus,’ where it was mined during the Roman era). Copper has an atomic number of 29 and atomic weight of 63.54 grams per mole. It is an element in Group 11 of the periodic table, sharing many properties with silver and gold.

Exploration: Finding minerals. One of the most important steps in mining is to find the minerals. Most minerals are found everywhere in the lithosphere, but in very, very low concentrations, too low to make mining profitable. For mining to be profitable, high quality ore needs to be found in a small area.

Copper Life Cycle. From its original home in the earth’s crust, copper passes through several stages to reach a long life in essential products like electronics, appliances, electrical grids, vehicles and renewable energy technologies. As a 100% recyclable material, copper can be reused over and over again with no loss to its physical properties.

Ore is mined and processed at an onsite flotation processing plant capable of treating up to 24 million tonnes per annum (Mtpa). The plant currently recovers copper, gold and silver into a saleable concentrate. The primary ore is crushed and ground using Semi-Autogenous Grinding and Ball mills to a final grain size of approximately 180 microns.

· Modern smelters are designed to collect at least 90 percent of the sulfur in the feedstock. These steps result in the following reaction: 2 CuFeS2 + 2 SiO2 + 4O2 → Cu2S + 2 FeSiO3 + 3SO2. Copper extracted by this method is combined with slag to create a material known as Matte Copper due to its matte look.

· Copper ore is typically mined through two primary methods: open-pit mining or underground mining. In open-pit mining, large pits are dug into the earth using heavy machinery, and the ore is extracted from the rock. Underground mining, on the other hand, involves tunneling into the earth to reach the copper deposits. 2.
