One method of mining tungsten ore comes from what is often referred to as slashing out the ore. Essentially, miners will drill directly into the tungsten ore deposit to carve out large chunks of the ore. While other mining operations could use what is often referred to in the mining world as room and pillar mining methods.

Mining is the extraction of valuable minerals or other geological materials from the earth, usually from an ore body, lode, vein, seam, reef or placer deposit.These deposits form a mineralized package that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay.
Gravity separation is one of the oldest technique in mineral processing but has seen a decline in its use since the introduction of methods like flotation, classification, magnetic separation and leaching. Gravity separation dates back to at least 3000 BC when Egyptians used the technique for separation of gold.

3 Technologies in Exploration, Mining, and Processing
The life cycle of mining begins with exploration, continues through production, and ends with closure and postmining land use. New technologies can benefit the mining industry and consumers in all stages of this life cycle. This report does not include downstream processing, such as smelting of
The other parameter that SGS experts consider when designing refractory gold treatments is whether or not to preconcentrate the gold bearing ore. This is usually done by flotation of arsenopyrite, pyrite, or other gold bearing sulfides. To be economically justifiable, preconcentration should meet two objectives.
