Effect of Chrome Ore Quality on Ferrochrome Production Efficiency. EFFECT OF CHROME ORE QUALITY ON By analysing the results obtained from smelting, the MgO structural form in the chrome ore, chromite grain size, »More detailed 2018-3-6 By analysing the results obtained from smelting, the MgO structural form in the chrome ore, chromite grain size, » More detailed! ingentaconnect Estimating effect of chrome ore granulometry on Estimating effect of chrome ore granulometry on It was found that ore granulometry, i.e. particle size, and due to different 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 Reaction of these materials produces slag and liquid ferrochrome, which are withdrawn from the hearth, and carbon monoxide, which rises through the descending charge. 1976-1-1 Two factors in particular have been identified as having an influence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. 2015-5-22 the smelting of charge chrome / ferro chrome production. Appropriate briquetting parameters like molasses and lim e binder level, molasses quality, particle size dis-tribution and segment condition etc. are essential to guarantee quality briquettes in the successful use of bri-quette and chromite ore 2021-3-12 effect of chrome ore size on smelting. Smelting chrome ore ScienceDirect Two factors in particular have been identified as having an influence on carbon content the particle size of the ore and the MgOAl 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 MgOAl ratio of 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 [1]. 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.
