This stage is typically what we envision when we think of mining.

Mining Wikipedia

Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef, or placer deposit.These deposits form a mineralized commodity that is of economic interest to the miner.

Mineral processing, mineral beneficiation, or upgradation involves handling three primary types of ROM material, which have been blasted, fragmented, and brought out from an in situ position. These materials can be used directly or by simple or complex processing and even by applying extractive metallurgy like hydrometallurgical or pyrometallurgical methods.

Related extraction techniques, herein lumped into the broad category of in-situ mining, include: (1) extraction of water-soluble salts (e.g., halite mined to produce caverns in salt domes in Gulf Coast states); (2) brine extraction (pumping of brines to the surface to remove valuable, naturally dissolved materials, such as lithium in Clayton

Mining valuable minerals from seawater: a critical review

Although methods of mining valuable minerals from seawater and seawater desalination brine have been reported in the literature on an individual mineral basis, to our knowledge, in recent times, only the study by Shahmansouri et al. reviewed the extraction methods of a large number of minerals in a single paper. 11 However, the emphasis in
