The Efficiency of Mechanized Mineral Processing Techniques to Recover Tin and Tantalum Ores. Case Study: Nyamatete Concession, Rwanda

Mining activities have resulted in a large volume of tailings containing certain proportion lost minerals, making them potential reprocessing opportunity, and information on mineral is often scarce. In this study, conceptual framework was established used to produce meaningful knowledge from the Nyamatete mine at HABATU Company Limited (an ASM Rwanda). Tailings particles were investigated based observed lithology determine their distribution over tailing dams, site-specific sampling approach procedure established. Sieving collected samples, particle size analysis, chemical analysis using XRF chosen as methods for characterization. Raw materials such SnO2, minor Ta2O5, Nb2O5 elements environmental importance Mn, Co, but small quantities are largely predominant quartz vein, been discovered tailings. The comminution gravity separation by mechanical facilities improved Cassiterite recovery 43.9 % compared artisanal processing method. SnO2 19.4 29.9 with grades 63.224 76.6 obtained pegmatite respectively. According scoping Habatu an appropriate grade, valuable content occurs recoverable grain-size range, total ore amount scales required input equipment. mechanized equipment advantageous because it improves efficiency while also treating material previously unknown ore, thereby significantly increasing processed Run Mine.
