The method of underground mining methods used depends largely on the mine and essentially what ends up being a more costeffective and safe path. One method of mining tungsten ore comes from what is often referred to as "slashing out the ore".
Tungsten is commonly used in heavy metal alloys such as high speed steel, from which cutting tools are manufactured. It is also used in the socalled 'superalloys' to form wearresistant coatings. Its density makes it useful as ballast in aircraft and in Formula 1 cars and more controversially as supersonic shrapnel and armour piercing ammunition in missiles.
