What are manganese ore fines and how are they sintered?

18-12-2017· Fines are the fine particles of manganese ore created when crushing manganese rocks. The fines are heated to sinter them (make them stick together, or become “agglomerated”). “The mines produce a lot of fines,” Hockaday explained. “But they can’t sell them, as furnaces won’t buy materials that are too fine.”

Sintering characteristics of manganese ore fines from

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 produced. The sinters showed a high degree of reduction and even metalization was noticed.

Utilisation of ore fines by agglomeration with special

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 bucket elevator to the hopper above the sintering strand.

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 chemistry and phenomena of the sintering process

Strengthening pelletization of manganese ore fines

06-09-2014· However, manganese ore fines are mainly agglomerated by sintering due to its high combined water which adversely affects the roasting performance of pellets. In this work, high pressure roll grinding (HPRG) process and optimization of temperature elevation system were investigated to improve the strength of fired manganese ore pellets.

Process for transforming fines of iron or manganese into

Ore fines whose particles are nearly all below 150 microns in size are converted into material suitable for use in forming sinter by the addition of agglomerants to these ore fines, the subsequent pelletizing of the mixture into spheres with a maximum size range of 6 mm, and the hardening of the spheres by curing them at temperatures below 300° C.

A Case Study ofthe Production ofHigh-grade Manganese

ficiating manganese ores by means of an agglomeration process were started in the 1970's. These investigations resulted in Ihe erection of a 500 ktla sinter plant at Samancor's Mamatwan manganese mjne in 1987. This plant initially produced a 44 per cent manganese sinter from a feed of 38 per cent carbonaceous manganese are.
