Tungsten: extraction and processing-MetalpediaThe common tungsten extraction methods are surface (or open pit) mining and sub-surface (or underground) mining, or a combination of both. . Surface mining; Open-pit mining is used if near-surface ore body is massive or when it occurs in steeply-dipping lode(s), sheeted vein systems, pipes, or makes up the bulk of the.Tungsten Metallurgy - 911 Metallurgist“Recover your mineral as soon as free,” is very important for all tungsten ores since tungsten minerals are not only brittle but heavy and will definitely be overground in conventional closed circuit grinding systems. It is for this reason stage crushing, screening, and gravity concentration.
