Dat gaat vaker voorkomen, kwam dit tegen in de laatste uitgave van T.I.C. Bulletin:
The re-birth of tantalum in Western Australia
by Ken Brinsden and Anand Sheth, Pilbara Minerals Ltd
The re-birth and significance of tantalum production from Western Australia as one of the largest, low cost stable suppliers globally. In the past 3 decades, tantalum production from hard rock resources in Western Australia carried the cost for lithium production, as a by-product, but this is now changing with the advent of e-transportation (electric vehicles and e-bikes) and Energy Storage Solutions for the renewable energy sector, made possible by use of lithium batteries. The demand for lithium primarily in these new and burgeoning industries is expected to triple in the next 10 years. Lithium hard rock deposits will become a significant supplier to this sector and several new lithium projects will be commissioned within the next 2 years in Western Australia and a few more in Canada. Some of these new projects, including the existing largest lithium operations, have a significant capacity to produce tantalum as a by-product, at a very commercially profitable cost. These companies are located in risk free jurisdictions / countries, with operations that can produce and supply a high-quality product consistently at competitive prices. These operations will be sustainable and meet all the environmental and ‘conflict-free’ regulatory requirements. The presentation will discuss the production volumes and costs of tantalum concentrates as a by-product of several hard rock lithium mines and shall provide an update on Pilbara’s Pilgangoora lithium – tantalum project, soon to become one of the largest producers and suppliers of lithium and tantalum concentrates.

A key issue will be the future of hard-rock lithium supply and how this might impact on by-product tantalum supply. Also addressed will be the outlook for tin and tin slags. The history of tantalum has seen it go from being a by-product to a main product and it now seems quite possible that it will go back to being a by-product again.
