Responses Of Ka’Oje Metallurgical Manganese Ore To Gravity Concentration Techniques, R. A. Muriana Jul 2015

Responses Of Ka’Oje Metallurgical Manganese Ore To Gravity Concentration Techniques, R. A. Muriana

Innovative Research Publications IRP India

Metallurgical manganese ore samples from Ka’oje (Nigeria) were enriched to higher Metallurgical grades during wet gravity separation techniques which included Jigging and Tabling operations. As-mined samples S1 (36.83%MnO), S2 (47.85%MnO), S3 (58.85%MnO) and S4 (54.96%MnO) were dressed and screened to -780+500 μm, -500+355μm, -355+250 μm, -250+192 μm and -192 μm particle size ranges. Obtained Jigging test concentrates assayed 51.54% MnO minimum recovery level with an enrichment ratio (ER) of 1.02; while Tabling operation concentrates assayed 91.11% MnO maximum recovery and 1.14 ER value. These responses demonstrated the suitability of the two techniques in raising the enrichment levels of the ores …
