The use of briquetted chrome ore fines in the production of Ferrosilicon Chrome and High Carbon Ferrochrome has yielded positive results over a period in excess of twenty-five years.
The use of briquetted chrome ore fines in the production of Ferrosilicon Chrome and High Carbon Ferrochrome has yielded positive results over a period in excess of twenty-five years. Of the three industrially used methods of agglomeration of chromite ores; sintering, pelletisation and briquetting, briquetting is preferred because the other two

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 fines.
3.1 Briquetted Chrome Ore Fines Utilisation in the Furnace Lumpy chrome ores remained the major expensive cost element in smelting which necessitated the need to increase the proportion of briquettes feed to the furnace sustainably. Increased use of fines
May 08, 2011· The recovered ore concentrate can be briquetted using a combination of molasses (7%), cement (3%) and bentonite (1%) to produce suitable agglomerate for metallurgical applications. The process flow sheet shown in Fig. 6 has been proposed and tested at a plant scale to utilize low grade manganese ore fines.
By screening manganese ore fines on 30 mesh screen and by utilising + 30 mesh fines only, 20 to 40 % of fines of 30 mesh size get rejected. Hence in another trial only unscreened manganese ore fines were used and lime was added to the extent of 0.5 to 1 %. Lime acted as binder for fines and balls were formed in balling drum.

Briquetted Chrome Ore Fines Utilisation In Ferrochrome Production At Zimbabwe Alloys International Ferroalloys Congress (INFACON) February 2, 2004 The paper discussed the application of briquetting technology to overcome the constraint posed by the friability of chrome ores.
Research highlights High tailing losses from the existing chromite plants (920% Cr 2 O 3). Accumulation of huge amount of low and sub-grade fines (1030% Cr 2 O 3). Utilization of stockpiled tailings containing chromite values. Concentrate with required Cr 2 O 3 content and Cr/Fe ratio. Unrecoverable ultrafine chrome particles.
Briquetted Chrome Ore Fines Utilisation in Ferrochrome Production at Zimbabwe Alloys. As a rule and on average the use of fines have massive cost advantages as the fines are a byproduct of screening and would otherwise have had no value apart from handling and processing costs. This use of
May 08, 2011· The recovered ore concentrate can be briquetted using a combination of molasses (7%), cement (3%) and bentonite (1%) to produce suitable agglomerate for metallurgical applications. The process flow sheet shown in Fig. 6 has been proposed and tested at a plant scale to utilize low grade manganese ore fines. It was found that these agglomerates can successfully replace 15% of high

BRIQUETTED CHROME ORE FINES UTILISATION IN FERROCHROME PRODUCTION AT ZIMBABWE ALLOYS N.R. Shoko and N.N. Malila Zimbabwe Alloys Limited, P.O.Box 530, Gweru, Zimbabwe. E-mail: [email protected] and [email protected] ABSTRACT The ever-increasing pressure on the profit margins of ferro-chrome producers and the .
Three possibilities of coal-based solid-state reduction of briquetted fine ore are discussed. The first one is still in laboratory scale and it employs production of self-reducing briquettes for
The fines produced during the process can be briquetted to make them suitable for use in steelmaking. Both quicklime and dolomite can be briquetted without binders. Typical capacities lie between 5 and 20 t/h per briquetting line. Sodium cyanide - Sodium cyanide is used in the leaching of gold ores. The chemically processed, fine-grained powder tends to become clumpy, however this can be effectively
Chrome Ore Briquetting - Briquette Machine. Welcome To Metco, Chrome ore fines are converted in briquettes for charging into furnace during the process of manufacturing ferro chrome briquettes are made in the briquetting press mixing the chrome ore with suitable binder and. Get Price
The fines may be agglomerated at the smelters, either by briquetting or using the Outokumpu pelletisation and preheating system, to reduce the amount of lumpy ore and chip required. Further gravity separation and elutriation steps yield the specific grain sizes and reduced levels of impurities, such as silica, required for the chemical and
Sep 29, 2014· GCP wet sludge (in case of wet gas cleaning) from the clarifier is dried and is either blended with the iron ore fines in the raw material yard or briquetted and recycled in sinter making. Refractory waste from the ladle repair shop is sold and the same is used by the refractory manufacturer in the manufacture of mortars.
Steel plants generate huge amount of wastes like iron ore fines, flue dust, granulated slag, mill-scale, coke breeze etc. These wastes are briquetted using organic, inorganic binders and also

The largest Fe ore producers in South Africa are investigating -1mm fines processing to reduce its cost of production by utilising its -1mm tailings material that are easily accessible and high grade (~55-60% Fe). To compete in the global market the major South African iron ore producers are investigating ways to
Mintek has been researching the beneficiation of fine iron ore over the last three years to fulfil some of the strategic needs outlined in South Africas National Development Plan and Beneficiation Strategy, namely the treatment of low-grade ores, tailings treatment and maximising resource utilisation, job retention in the iron ore and chrome
