Desulphurization of Agbaja iron oxide ore concentrate using solid pot assium xochlorate (V) (KCI0 3 ) as oxidant has been carried out [7]. The con centrate was treated at a temperature range ...

As the ultrafine iron ore concentrate was used to prepare green pellets, the main problem was the serious cracking during the drying process. The fine particles contacted so closely that the ...

The paper presents technological and configuration solutions for new complexes of cast iron desulphurization by mono-injection of magnesium in the medium-size ladles (80–130 tons of cast iron). As a result, cast iron desulphurization (up to ≤ 0.001% of sulfur content), ladle slag correction, and cast iron purification from sulfur are …

In this research, an effort is made to separately introduce the various processes, industrial practices, and fundamental research activities to remove sulfur from iron ores, concentrates, or roasted iron ores.

FIELD: ferrous metallurgy. SUBSTANCE: desulfurization of liquid cast iron is performed using high-basicity liquid ladle slag and powder desulfurizer. Method is distinguished by that high-basicity liquid ladle slag formed during out-of-furnace treatment of molten steal and containing (wt %) CaO 45-70, SiO 2 2-17, MgO 4-8, Al 2 O 3 14-22, FeO 0.5-6 and the …

The designed process under the optimized desulphurization conditions was applied to a real iron ore concentrate. More than 75% of the total sulphur was …

The designed process under the optimized desulphurization conditions was applied to a real iron ore concentrate. More than 75% of the total sulphur was removed via the leaching process.

The time consumed by the operation varies with the ore treated and the degree of desulphurization required; any sulphur in the concentrate is readily eliminated. ... The products from the old mill carried from 65 to 71 per cent. iron in the concentrate and 1 to 1½ per cent. iron present as magnetite in the tailing; the new mill concentrate ...

Two methods were examined for desulfurization process using reverse floatation: 1) grinding the produced concentrate by low intensity magnetic separators (Final concentrate of …

1. Introduction. The high amount of sulfur in iron ores causes different problems in the production of iron concentrate, pelletizing (environmentally harmful emission of SO 2), …

Magnesium is used for the desulphurization of iron from the blast furnace, yet the kinetic reaction mechanism is unknown. In order to calculate the specific dissolution rate from the magnesium bubbles, a preliminary study was conducted on argon bubble formation in 60 kg heats of carbon-saturated iron at 1523 K. The frequency of

Desulphurization of iron ore was carried out using an oxidant; powdered potassium chlorate (KClO 3) of mass-input range (5-12g) and temperature range (500-800°C). The limit of desulphurization was

Model for Predictive Analysis of the Concentration of Sulphur Removed by Molecular- Oxygen- Induced Desulphurization of Iron Oxide Ore

The preparation of high-quality iron concentrate from pyrite cinder by means of desulphurization has potential industrial applications. On one hand, the comprehensive utilization of pyrite cinder can be achieved, while on the other hand, the environmental problems that it causes can be solved effectively. In this study, the desulfurization …
