A process for sintering manganese ore was developed by Outokumpu with equipment proven in the sintering of chromite . In the process,manganese ore fines are micro-pelletised and/or nodulised, sintered on a steel belt and then crushed to the proper size. Special attention is paid to the Manganese ore fines generated at Balaghat and Ukwa mines of MOIL were subjected to sintering studies at the R&D Centre of Paramount Sinters Pvt. Ltd. The studies indicated that fluxed sinter with very good strength and porosity could be Sintering Manganese ore fines is mixed with 6% coke fines of 3 mm size and 30% return fines. The mixture after thoroughly drying is charged into a pelletizer where 6% water is added. The pelletizer revolves at a speed of 10-15 R. P. M. The pellets are transported by belt conveyor and The effects of sintering time, temperature, moisture content, gas atmosphere, gas flow rate, thickness of a sample, and addition of manganese ore to the dust on zinc removal in sintering Manganese Sinterfrom Low-gradeMamatwan Manganese Ore P. C. PlENAAR and W. F P. SMITH MamatwclIl Manganese Mille, Samallcor Ltd. South Africa has 13,6 billion tons of manganese ore with a manganese content of more than 20 per cent, and is a major producer of manganese sintering. EXPERIMENTAL Two ore samples from the Kalahari manganese fields (A & B) as well as a sample from the Postmasburg ferruginous manganese deposit (C) were sourced from a South African high carbon ferromanganese producer. The ore samples were fines (-6 mm size fraction) and unsuitable for feed to a submerged arc furnace. After beneficiation & sintering / pelletization of iron ore, beneficiation and sintering of manganese ore fines attracted technology experts due to massive expansion in manganese based ferro-alloys. Fast depleting high grade lumpy manganese ore deposits made the beneficiation and sintering all Wessels ore had high iron oxide and calcia content, and low concentration of silica. Major manganese-containing phases were bixbyite, braunite, manganite and hausmannite in Wessels ore, and pyrolusite in Groote Eylandt ore; both grades of Groote Eylandt ore con-tained silica inclusions. In the process of sintering in air and argon at 1000°C, MnO The mixture of fine manganese ore, manganese furnace dust, returns and coke, with addition of zinc oxide in some experiments, was charged into a sintering pot.
