Abstract
Minerals containing Tantalum and Tin are considered conflict minerals, once the mining, transport or export of these ores have been related to financing of abuses to human rights or armed conflicts. In this scenario, corporate organizations and policy makers are constantly working on new regulations and requirements, in order to prevent companies from financing these issues. As consequence of these necessary efforts, the supply chain of tantalum and tin is already being affected and there may be a limitation of raw material availability for companies worldwide. Companies must adapt to new requirements while also looking for alternative materials such as secondary materials and/or byproducts of tantalum and tin the world and in Brazil, the necessary changes that Brazilian companies must go through considering this evolving scene and the possibilities for the metallurgical recovery of tantalum and tin from byproducts in Brazil. This recovery can help to enhance production levels, while not contributing to the financing of the described abuses.
