Open-pit mining is common for shallow deposits, whereas underground mining is employed for deeper ore bodies. Processing tungsten ores is complex due to the presence of other minerals, and gravity, flotation, magnetic, and electrostatic methods are often employed to separate the tungsten. ... The global tungsten mining industry is …
Surface mining, also called open pit mining, is used if near-surface ore body is too large or if it occurs in steeply-dipping lodes, pipes, sheeted vein systems, or makes up the majority of the rock in question.
It was mothballed 30 years ago due to softening prices, but work is now underway to redevelop the open pit mine. It's an important project. Tungsten has been classified as a critical mineral by most governments around the world, including Australia, and Dolphin is one of the highest grade tungsten deposits in the Western world with an …
