| Abstract Scope |
Bismuth is found in numerous mineral deposits and is typically considered an undesirable by-product. However, its designation as a critical raw material and mineral by the European Commission in 2017 and the USA in 2018 has renewed interest in bismuth production and security architectures. These among others have made demands for bismuth and its defined compound to gain considerable attention as a lead substitute in alloys and chemicals industries. Thus, this study explored low-cum-ecofeasible energy parameters in the preparation of bismuth compounds from an indigenous bismutite ore through acid leaching for industrial value addition. The effects of parameters such as lixiviant concentration, reaction temperature, and particle size on bismuth recovery were thoroughly examined. Under the established optimal conditions, the low-energy leaching process yielded 97.9% efficiency. The resulting bismuth leach solution was further processed to produce a high-purity bismuth compound recommended for use in bismuth-based alloys application. |
