Copper ore

Tantalite

quartz and Feldspar Vermiculate

 

 
Coltan is the industrial name for columbite–tantalite, a dull black metallic ore from which the elements niobium (formerly
"columbium") and tantalum are extracted. The niobium -dominant mineral is columbite , hence the "col " half of the term.
The mineral concentrates  dominated by tantalum are  referred to as tantalite . When coltan is refined it becomes a heat
resistant powder with high permittivity. Refined coltan is a critical element in creatingcapacitors, which are used in a vast
array of small electronic devices , especially in mobile phones , laptop computers , pagers , and other electronic devices.
Tantalum from coltan is used in consumer electronics products such as cell phones,DVD players,videogame systems and
computers .Tantalum is also produced as a by-product of tin mining and smelting.
