How do we extract minerals? USGS

The primary methods used to extract minerals from the ground are: Underground mining; Surface (open pit) mining; Placer mining The location and shape of the deposit, strength of the rock, ore grade, mining costs, and current market price of the commodity are some of the determining factors for selecting which mining method to use.get price

Mineral Extraction The Environmental Literacy Council

Longwall mining allows for increased mineral extraction to occur, since it shears entire blocks of mineral onto a conveyor belt through the use of self-advancing, hydraulic roof supports or shields. Once the mineral is extracted, the supports move on and the roof is allowed to collapse.get price

What are the main methods of mining? American

There are four main mining methods: underground, open surface (pit), placer, and in-situ mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments.get price
