  • 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 mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environmentsGold mining is the process of mining of gold or gold ores from the ground There are several techniques and processes by which gold may be extracted from the earth Placer mining is the technique by which gold that has accumulated in a placer deposit is extracted Placer deposits are composed of relatively loose material that makes tunnelingMethods of Gold Mining Geology InApr 12, 2018· For a mining company, sustainable practices are at the core of its license to operate More and more companies have come to realize that the only way to be economically viable is to operate environmentally and socially responsible The themes of climate change, resource scarcity and energy efficiency strongly resonate with the mining industrySustainability Strategies in Mining | Sustainability
