  • What are the main methods of mining? | American

    There are four main mining methods: underground, open surface (pit), placer, and insitu 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 miningIn the case of artisanal mining, the extraction process usually takes a longer time as it involves low tech equipment and manual labor Compared to alluvial mining, the postprocessing is shorter and is a less resourceconsuming task as diamonds areHow Are Diamonds Mined And Extracted From the Ground
