Due to the randomness of all factors influencing the sintering operation, a two-stepped procedure is proposed to find the best way of using stocked fines at a plant producing Fe-Mn alloys for the steelmaking industry. The approach is based on the following: (1) predict the result of the sintering operation by establishing the best multilinear regression model …
Manganese (Mn) ore deposits in China are geologically interesting not only because of their sizes (many reaching world-class), but also their widely varied metallogenic epochs from the Mesoproterozoic to the Early Mesozoic (Hou et al., 1997, Fan and Yang, 1999, Fu et al., 2014), although the majority of the ore deposits were formed in the …
Abstract In this study, the use of XRF, XRD and other instruments found that the manganese content in the ore was 14.53%, and the main forms were carbonate, iron manganese oxide and manganese oxide. Because of the special magnetic susceptibility of these minerals, the magnetic separation method was chosen to improve the grade of …
The author has worked for almost three decades in this area and has extended the sintering technology to manganese ore fines and chromite fines. In case of chromite, the temperature required for sintering is about 200 0 C more than that required for iron ore sintering. The process conditions for manganese ore sintering are almost …

The main metallogenic epochs of manganese ore deposits of China are Sinian and Devonian, in contrast with the famous Proterozoic, Cretaceous and Oligocene manganese deposits elsewhere in the world. ... carbonate rock type. Following the accepted usage, we have defined mudrock as a class name of fine-grained terri- …
Direct use of manganese fines in the submerged arc furnace (SAF) will lead to the low permeability of the charge, essentially increase the consumption of coke and electric energy. In order to make better use of manganese fines as well as to save energy and cost in the industry, the sintering process of manganese ore is particularly important.

This allying technique is in use for high alloyed (stainless), low alloyed and carbon steel. The elements reviewed include chromium, nickel, molybdenum, vanadium and manganese. Raw materials used to this purpose are lump ores, ore fines, special slags, self-reducing briquettes and others.
Manganese ore fines is multicoloured and usually brown to black. Its colour and texture may vary due to variations of the manganese and gangue minerals present. It is a very heavy cargo with typical moisture content up to 15% by weight.
Manganese Ore Fines Agglomeration. Manganese Ore an overview ScienceDirect Topics. 5.3.7 Manganese Ore. Manganese ore is required in iron making to control the manganese content of the hot metal in the desired range. Unlike other plants, where manganese ore lump is used directly in blast furnace, in VSP, it was proposed to use …
