We are able to supply Tin in many forms including LME registered and non registered, ingots, slabs, bars, foil, granules, powder, anodized activated powder, shot, wire, sticks, ingots, and “mossy tin”. Tin is a silvery-white metal, is malleable, somewhat ductile, and has a highly crystalline structure. The element has two colours, with a cubic structure which changes at allotropic forms. On warming it is grey, the ordinary form of the metal. When Tin is cooled below 13.2°C, it changes slowly from white to grey or tetragonal structure. This change is affected by impurities such as Aluminium and Zinc, and can be prevented by small additions of Antimony or Bismuth.

Coltan/ Tantalite materials available in stock.
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.
