Effect of slag basicity in ferromanganese production
2017-5-26 The chemical composition of ferromanganese and slag was analysed with X-ray fluorescence. From this experiment, the optimum slag basicity was 0.8 that produced 8.2 kg of ferromanganese with 78.1% Mn, 12.7% Fe, and 8.9% Si. It resulted from 30 kg of manganese ore, 7.5 kg of cokes, and 12 kg of limestone.

Effect of slag basicity in ferromanganese production
ABSTRACT Ferromanganese is one of the most important alloying elements in steel industries. In this work, the production of ferromanganese was carried out using three-phase submerged mini electric arc furnace. The effect of slag basicity due to the addition of a various amount of limestone as fluxing agent on this smelting process was investigated.

THE EFFECT OF ALUMINA IN FERROMANGANESE SLAG
2015-5-22 easy to draw the conclusion from Figure 2: that the effect of basicity on th e MnO solubility is larger than that of the A/S ratio. A change in the basicity from 0.4 to 0.8 lowers the solubility of MnO in the slag considerably. Figure 3: demonstrates the effect of slag basicity on the liquidus content of MnO for a fixed A/S ratio 0.5.

The effect of basicity of two different basic charges for reduction of MnO by solid carbon during smelting ferromanganese is considered. The effect of different charge compositions on MnO reduction in the temperature range 1400–1500°C is considered. Experiments are performed in a thermogravimetric furnace in the presence of CO at atmospheric pressure.

Slags in ferroalloys production—review of present
2009-8-26 slag is rich in manganese oxide up to above 30%. A common feature is that the ‘ore oxides’, CrOx and MnOx in slag are not only divalent oxides but also contain some higher valent of Cr3+ and Mn3+, respec-tively. In FeMn production conditions the slag consists mainly of Mn2+. This is a clear difference from CrOx containing slags in which

The composition of ferromanganese slag is very important as it determines the slag/metal equilibrium relations including MnO content of final slag, melting relations and slag viscosity. The slag composition is further expected to influence the process temperature. The properties of ferromanganese slags are suitably described by its basicity and A/S mass ratios.

2020-2-24 Abstract: The reduction and liquidus behaviour of manganese slag with different basicities were studied in non-isothermal experiments in the temperature range of 1400–1500 C. Certain amounts of quartz were added to Assmang ore (South Africa), and lime was added to Comilog ore (Gabon), to adjust the charge basicity to 0.5, 0.8 and 1.2.
