Tantalum as an investment can be a rather contentious topic among finance experts. Others call it a conflict resource and have linked the use of the metal to the war in the African country once known as Zaire. This war is sometimes called the African World War, and it involved 9 countries and about 20 separate armed groups.

Abstract. Chlorination and carbochlorination of tantalum and niobium low-grade concentrate (LGC) and high-grade concentrate (HGC), obtained by leaching of tin slag, were studied using Cl 2 + N 2 and Cl 2 + CO + N 2 gas mixtures. Thermogravimetric analysis and conventional boat experiments were performed between 200 °C and 1000 °C.

Niobium and tantalum - pubs.er.usgs.gov

Niobium and tantalum are transition metals that are almost always found together in nature because they have very similar physical and chemical properties. Their properties of hardness, conductivity, and resistance to corrosion largely determine their primary uses today. The leading use of niobium (about 75 percent) is in the production of high-strength steel alloys used in pipelines ...

Where is Tantalum Mined | TIC

In Brazil, Malaysia and Thailand,the tin industry provides tantalum as a component of the tin slag by-product, that arises from the smelting of cassiterite ore concentrates for tin production. Struverite concentrates (a Ti-Nb-Ta mineral) have historically also been available from northern Malaysia containing 9-12% tantalum oxide.

However, the tin concentrate grade of 40% is required, meaning the enrichment of hundreds or thousands times. Targeting at the refractory tin ore, low grade tin concentrate is obtained and it has to be further extracted by special metallurgy process. Reduction smelting is the dominant process to extract tin metal from tin concentrate.
