Technical Fact Sheet – Tungsten . January 2014 . Disclaimer: ... DoD began using tungsten as a replacement for lead in bullets in 1999 for training. In early 2003, the production of tungsten/nylon bullets was discontinued based on flight instability issues (ATSDR 2005; USACE 2007).
Note: The weights given in these tables are necessarily approximate; variation within a class of substance can be large. I have taken an average weight per cubic metre for a given substance and rounded it to the nearest 25 kilograms. The exception is the Metals table, since there is seldom much variation in weight between different batches of the same metal I have given the weight per cubic ...

Galena, also called lead glance, is the natural mineral form of lead(II) sulfide. It is the most important ore of lead and an important source of silver. Galena is one of the most abundant and widely distributed sulfide minerals. It crystallizes in the cubic crystal system often showing octahedral forms.
Tungsten Ore is a world generation ore block added by the Magneticraft mod. It generates on layers 1 to 16 and is relatively rare. Tungsten Ore is needed to make Tungsten Ingots, which in turn are used to make Carbide Ingots, which are needed for many of the machines in this mod.. Magneticraft Tungsten Ore is easier to distinguish from Coal Ore than RedPower 2's Tungsten Ore as it is much lighter.
This is most commonly used on Galena (Silver+Lead) and Ilmenite (Titanium+Iron) dusts. Chemical Reactor : Few purified crushed ores (just Chalcopyrite and Pentlandite) can be processed in a Chemical Reactor with 8000mb of Nitric Acid to yield a tiny pile of Platinum Group Sludge and 9000mb of Vitriol.
