1975-6-1 SMELTING REACTIONS In the smelting process the electric furnace is charged with the chrome ore, a carbon reducing agent, and a flux, usually quartz. Reaction of these materials produces slag and liquid ferrochrome, which are withdrawn from the hearth, and carbon monoxide, which rises through the descending charge.
1976-1-1 Two factors in particular have been identified as having an influence on carbon content; the particle size of the ore, and the MgO/Al 2 0 3 of the slag. Smelting chrome ore 855 Low carbon levels are more readily attained with a lumpy, coarse ore and when the slag has a MgO/Al 2 0 3 ratio of approximately unity.
2017-2-4 With the combined effect of more ores and less quartzite, the smelting process produces more slag and requires more electric energy to heat and melt the slag. Keywords—ferrochrome production, ferroalloy process optimization, chrome ore I. INTRODUCTION igh carbon ferrochrome (HCFeCr) is produced by carbothermic reduction of chrome ore.

2018-6-12 It was found that ore granulometry, i.e. particle size, plays a vital role in the pelletisation process by controlling the number of contact points for bond formation and due to different liberation and smelting
2010-1-5 2. CHROME ORE SPECIFICATIONS The ore is of podiform deposit that has been highly tectonized, thus the small grain size chromites have extensive microscopic intergranular cracks. The binder or veinstone is mainly serpentine with small quantity of magnesia (MgCO3) in veins of chrome ore. Melting temperature of the ore is 1650 1660°C .
2011-3-3 Ferrochrome smelting and smelting capacity investment in Zimbabwe J. Chirasha Zimbabwe Alloys Chrome, Gweru, Zimbabwe A schedule of chrome ore reserves was published in the early 1980s to show the distribution by quality and quantity. Table II shows the world reserves of chrome ore
