Coltan, short for columbite-tantalite, is a metallic ore primarily composed of two minerals: columbite (a niobium-rich mineral) and tantalite (a tantalum-rich mineral). Tantalum is a valuable metal used in various electronic devices, particularly in capacitors, due to its high capacitance and reliability.

Propylene carbonate (molecular formula: C4H6O3) is a colorless, odorless, flammable liquid. Miscible with ether, acetone, benzene, chloroform, vinyl acetate, etc., soluble in water and carbon tetrachloride. It has a strong ability to absorb carbon dioxide and is stable in nature. In industry, it is obtained by adding propylene oxide and carbon dioxide under a certain pressure, and then distilling under reduced pressure. It can be used as oily solvent, spinning solvent, olefin, aromatic hydrocarbon extractant, carbon dioxide absorber, dispersant for water-soluble dyes and pigments, etc.

Application
1. It can be used as an excellent medium for high-energy batteries and capacitors in the electronics industry.
2. In the polymer industry, it can be used as a solvent and plasticizer for polymers.
3. Used as a plasticizer for adhesives and sealants.
4. It can also be used as a phenolic resin curing accelerator and a dispersant for water-soluble adhesives, pigments and fillers.
5. The chemical industry is the main raw material for synthesizing dimethyl carbonate. It can also be used to remove
carbon dioxide and hydrogen sulfide from natural gas and petroleum cracking gas.
6. It can also be used in textile, printing and dyeing and other industrial fields.

We have currently have available 1000MT of Coltan / Tantalite with a purity of 30% in DRC with capacity to deliver 500 - 1000MT on a monthly basis.

The chemical properties are as follows:

a) Tantalum: 30.44 % Ta 40.01 % Ta2O5

b) Iron: 1.87 % Fe 10.98 % FeO

c) Oxygen: 10.69 % O

Coltan is (short for columbiteâ??tantalites and known industrially as tantalite) is a dull black metallic ore from which the elements niobium and tantalum are extracted. The niobium-dominant mineral in coltan is columbite (after niobium's original American name columbium), and the tantalum-dominant mineral is the tantalite.

Tantalum from coltan is used to manufacture tantalum capacitors which are used for mobile phones, personal computers, automotive electronics, and cameras.
