Carbon emission has increasingly become a topic of the day. Carbothermic reduction processes and energy generating units have for years used generic carbonaceous materials contributing to high carbon pollution. Ongoing investigations are showing good prospects. This paper corroborates a comprehensive review on the potential of biochar as an innovative and sustainable alternative to traditional carbon sources in pyrometallurgical processes, addressing the environmental ithreats caused by fossil fuel use, such as gr...

During the mining, handling, and processing activities, the production of fines is inevitable due to breakage of large particles caused by compression, abrasion, attrition and impact of the ore particles with one another and the equipment during beneficiation and handling. The fines generated as a result, are generally high-grade feed stock materials and add value to processes. Many attempts to recycle these fines have shown some limitations because of the quality of binders used for agglomeration. Pyrometallurgic...

The depletion of primary raw materials and the demand in High Tech has played a big role in finding new ways of getting raw materials including recycling. Germanium being a semi-conductor currently in high demand is being sourced from secondary materials. The purpose of this project was to recover Germanium from copper slag in the presence of pure silicon using the carbothermic reduction process. The experiment was designed using Minitab software with Taguchi as the tool for statistical analysis and to design the ...
