Mining of metal ores

NACE v2.1 Code: B07

About mining of metal ores

NACE code 07, 'Mining of metal ores,' encompasses the extraction of metal-bearing minerals from the earth's crust. This industry plays a crucial role in the global economy, providing the raw materials essential for a wide range of manufacturing and industrial processes. From the production of steel and aluminum to the creation of electronic components, the mining of metal ores is a fundamental pillar of modern society.

Production process

The mining of metal ores typically involves a multi-step process. First, exploratory activities are conducted to identify and assess the viability of potential ore deposits. Once a suitable site is selected, the ore is extracted through various techniques, such as open-pit mining, underground mining, or placer mining. The extracted ore is then processed, often through a combination of crushing, grinding, and separation methods, to concentrate the desired metal content. Finally, the concentrated ore is smelted and refined to produce the pure metal or metal alloy.

Production inputs

The mining of metal ores requires a significant investment in both capital and natural resources. Key inputs include heavy machinery and equipment for exploration, extraction, and processing, as well as a skilled workforce to operate these systems. Additionally, the industry relies on a steady supply of energy, water, and other consumable materials to sustain its operations. The availability and accessibility of the metal-bearing ore deposits themselves are also crucial to the industry's success.

Production outputs

The primary outputs of the mining of metal ores industry are the various metal products, such as 24 Manufacture of basic metals, 25 Manufacture of fabricated metal products, except machinery and equipment, and 26 Manufacture of computer, electronic and optical products. These metals are then used as inputs for a wide range of downstream industries, including construction, transportation, and electronics manufacturing.
