Coltan

Coltan is a mineral of tantalium, it is used for tantalium production. Coltan ore spawns in the overwold in one roughly 1000 block wide area similar to australian ore, but the location is random. To find the area use Coltass (upgraded compass) which will always point to the center of the deposit. It drops Coltan (not affected by Fortune enchantment)

It has a powder form which is used for the first steps of tantalium production. The powder is toxic similar to asbestos, a gas mask is recommended while working with any coltan related processing.

Uses
Coltan is used for further tantalium processing.

Purification process
Two coltan powders are purified with the use of 1 coal powder, 250mb of Hydrogen Peroxide and 500mb of Liquid Hydrogen in the chemical plant. The result is purified tantalite powder which is later used for Pandemonium(III)tantalite solution.
