  • How do we extract minerals? USGS

    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.

  • Mining : What is Mining? What are the 4 mining methods

    Four main methods of mining are available: underground, open surface (pit), placer and in-situ mining. Underground mines are more expensive and often used to reach deposits that are deeper. Surface mines are usually used for deposits that are shallower and less valuable.

    Did You Know?Open-Pit MiningQuarryingStrip MiningMountaintop RemovalDredgingDredging is a method of obtaining mineral deposits from the bottom of rivers, oceans, harbors, and streams. As compared to other mining methods, where the ore has to be accessed by removing material above it, in this case, the river makes the job easier by directly transporting minerals from upstream areas. Dredging involves scooping up mud from the bottom of the water body, removing the minerals from it, and releasing the waste back to the bottom. This technique does not cause large-scale disruptio
