A review on characteristics of silico-manganese slag and
2022-1-1 Silico-manganese slag is a byproduct of silico-manganese alloy production, and its major oxide components are SiO 2, CaO, Al 2 O 3, and MnO. It's chemical composition similar to blast furnace slag, except it is more acidic due to higher SiO 2 and lower Cao and also contains ∼10 wt.% MnO. Depending on the process of cooling, the molten slag is

2010-1-5 the relative amounts of manganese ores and HCFeMn slag in the raw material mix. A process temperature of 1600 to 1650°C is necessary to obtain metal with sufficiently high content of Si and discard slag with low MnO. FeMn slag has a relatively low melting temperature (about 1250°C) compared with Mn-ores. Accordingly, a high share of FeMn slag

Manganese Slag an overview ScienceDirect Topics
Silico-manganese (SiMn) slag is generated during the production of SiMn alloys, using the carbothermic reduction method in an electric arc furnace at 1600–1650°C. Approximately, 1.2–1.4 tons of SiMn slag is produced for every ton of SiMn alloy ( Criado et al., 2017 ). SiMn slag has a higher amount of SiO 2 but lower amounts of Al 2 O 3 and

Ferro-silico-manganese production from manganese ore
2020-11-1 One of the Ferro-silico-manganese uses is for molten steel de-oxidation process. The production of ferro-silico-manganese alloy uses manganese ore, quartz and iron ore as raw materials . The copper smelting slag is rich in iron and silicon, and thus is an attractive substitute for the quartz and iron ore in the ferro-silico-manganese production.
