Mining of metal ores

isic code 07, 'Mining of metal ores', encompasses the extraction and processing of metal-bearing minerals from the earth's crust. This industry plays a vital role in the global economy, providing the raw materials necessary for the production of a wide range of goods, from construction materials to high-tech electronics. The metal ores extracted through this industry are essential inputs for numerous other economic activities, making it a crucial link in the supply chain across various sectors.

The mining of metal ores typically involves a series of steps, including exploration, extraction, and processing. Exploration techniques, such as geological surveys and core drilling, are used to identify and assess the viability of metal ore deposits. Once a deposit is identified, extraction methods, such as open-pit mining or underground mining, are employed to remove the ore from the ground. The extracted ore is then processed through a variety of techniques, including crushing, grinding, and separation, to extract the desired metal concentrates.

The mining of metal ores requires a range of inputs, including heavy machinery, such as excavators and haul trucks, as well as specialized equipment for processing the ore. Additionally, this industry relies on a skilled workforce, including geologists, mining engineers, and technicians, to operate the equipment and manage the extraction and processing operations. Energy sources, such as electricity and fuel, are also essential inputs for the various stages of the mining process.

The primary outputs of the mining of metal ores industry are the metal concentrates and refined metals, which are then used as inputs for a variety of other industries. These include the 24 Manufacture of basic metals, 25 Manufacture of fabricated metal products, except machinery and equipment, and 26 Manufacture of computer, electronic and optical products industries, among others. The specific metal ores produced can vary depending on the location and geological characteristics of the deposits, but common examples include iron ore, copper ore, and gold ore.
