Understanding the Tungsten Extraction Process: …
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. The entire body of material is mined with no overburden being placed back into the void during the entire extraction process. With open pit mining, strip mining and dreading operations work as well.
Tungsten Mining & Beneficiation | International …
Open pit mines exist but are rare. Tungsten mines are relatively small and rarely produce more than 2000t of ore per day. Mining methods for tungsten ore are not at all exceptional and usually are adapted to the geology of the ore deposit. Most tungsten ores contain less than 1.5% WO 3 and frequently only a few tenths of a percent.
