#### Mineral processing metallurgy Britannica

Mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue. It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy.The primary operations are comminution and concentration, but there are other important operations

#### Mining engineering Wikipedia

Mineral exploration is the process of finding ores (commercially viable concentrations of minerals) to mine.Mineral exploration is a much more intensive, organized, involved, and professional process than mineral prospecting, though it does frequently use the services of prospecting.. The first stage of mining consists of the processes of finding and exploring a mineral deposit.

#### Deep-sea mining IUCN

• Deep-sea mining is the process of retrieving mineral deposits from the deep sea the area of the ocean below 200 m. • Depleting terrestrial deposits and rising demand for metals are stimulating interest in the deep sea, with commercial mining imminent. • The scraping of the sea floor and pollution from mining processes can wipe out entire species many yet to be discovered.

Once permitted the mining area will consist of less than 600 acres. It will be mined in phases of roughly 25-40 acres per month. The area in which mining actually occurs will range from only 1.5 to 2.5 acres and the land excavated will be backfilled, graded and covered with topsoil and seeds/seedlings (depending on the time of year) within 20 days following excavation.

#### 10 Different Types of Mining Operations and Mines Nayturr

#### Extraction of Resources Geology Lumen Learning

The process of mining from discovery of an ore body through extraction of minerals and finally to returning the land to its natural state consists of several distinct steps. The first is discovery of the ore body, which is carried out through prospecting or exploration to find and then define the extent, location and value of the ore body

#### Processes extraction, mining, smelting, refining

An ore is a rock containing enough valuable mineral to make it worth extracting. In the case of copper, it is worth extracting when there is about 2 kg of copper per 1,000 kg of ore (0.2%). Copper minerals are found in over one hundred varieties, although only a few have been worked for copper on a large scale.
