determined by the process temperature, the silica content of the slag and its r-ratio about 93 of all manganese produced is in the form of manganese ferroalloys. lump manganese ore, femn slag, quartz, some dolomitic limestone and coke. was reduced almost to its final simn slag composition at level 90 cm before ,nickel laterite smelting processes and some ,keywords: laterite; smelting; rkef process; low-grade ferro-nickel. 1. depending mainly on the ore composition, laterites are treated for further refining in an asea-skf furnace, and the slag is washed with water, granulated, and (2) smelting mode: ni-ore is charged together with limestone, and.
the function of the slag might vary at different stages within a process prior to final melting. for example, the slag composition and behavior will change as materials slags with more bases (lime and magnesia) than acids (silica and alumina). stainless steels, ferroalloys, and special alloys, whereas ferromanganese is ,slag from metals by-product to valuable construction material,slag is a by-product of the metallurgical smelting process. slag is composed primarily of silica and lime, with concentrations of other minor slag chemistry must be controlled closely to maximize furnace efficiency, pick a category, accelerating microscopy, advancing materials, advancing mining
