Tungsten in the form of finely divided powder is highly flammable and may ignite spontaneously on contact with air. Powdered tungsten may also cause fire or explosion on contact with oxidants HSDB 2009a NIOSH 2010. Tungsten ore is used primarily to produce tungsten carbide and tungsten alloys, which are
The U.S. relies heavily on imports of antimony metal and ore in the production of antimony oxide. This is because domestic ore has high levels of arsenic, making use of this ore unattractive. In 1988, a total of 33,106 tons of ore was imported into the U.S., with China being the largest supplier. Some other

Mar 01, 2012 Highlights Production- and consumption-based GHG inventories were completed for Estonia. The study focused on energy-related and non-energy-related GHG emissions. The IO analysis, the EEBT approach and the basic methods of the 2006 IPCC Guidelines were employed. The results demonstrated that the consumption-based CO 2 eq emissions were 18 higher than the production-based emissions.

Explanation After the filling of molten metal into the cavity, somewhat of melt still remains in the nozzle or sprue part. To avoid the wastage of melt, plunger is used, which by moving back returns the unused liquid metal to the gooseneck. This process saves a lot of molten metal and hence economizes the production.
