Types of Surface Mining American Mine Services

Highwall mining relies on machinery to collect ores from a “highwall”, or an unmined wall with overburden and exposed minerals and ores. Usually, highwalls are found at the edges of quarries and pit mines, and enable miners to retrieve ore from a wall that would otherwise be too expensive to clear of overburden in order to reach the ore.

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.
