Mining Methods • Environment Guide

Techniques for mining minerals in the marine environment may involve seafloor suction dredging, seafloor slurry pipes, use of tracked vessels on the seafloor and seafloor cutting/fragmentation. Following extraction and processing, tailings (unwanted material) are deposited back onto the seafloor.

How do we extract minerals? USGS

2 天前  Placer mining is used to recover valuable minerals from sediments in present-day river channels, beach sands, or ancient stream deposits. More than half of the world’s titanium comes from placer mining of beach dunes and sands. In placer operations, the mined material is washed and sluiced to concentrate the heavier minerals.

2020-3-12  Initially, the mineral closer to the surface would be mined using a surface mining method. After the minerals have been exhausted that way, the coal found deeper in the seam would be mined using an underground mining method. This allows for the most minerals in an area to be extracted, using the most efficient methods.
