Enhancement Of Iron Recovery From Steelmaking Slag Fines

Jul 28 2016 Steelmaking slags are usually processed for iron recovery by dry magnetic separation. The recovered iron-rich products are recycled back into the ironmaking and steelmaking processes to replace high-cost steel scrap and iron ores. However current slag processing is far away from optimum conditions especially for slag fines with small particle sizes resulting in generation of nonrecyclable .

Recovery Of High Grade Iron Compounds From Ld Slag By

Jan 10 2014 Evolution of FeO t a CaO b and P 2 O 5 c contents in the magnetic fractions of LD slag as function of intensity of magnetic field of wet magnetic separation. The grinding of steel slag and magnetic separation are necessary for a better separation of a high grade iron compounds which can be directly recycled in converter steel mill.

Characterisation And Magnetic Concentration Of An Iron Ore

Jan 01 2019 Fig. 1 shows the particle-size distribution of the iron ore jigging tailings sample and the concentration feed sample grindingclassification at 1.4 mm.As observed the d 80 of the tailings sample is approximately 4000 m 4 mm with only 4 of the particles below 37 m 0.037 mm. The d 80 of the concentration feed sample is 840 m 0.840 mm with only 4 of particles below 10 m 0 .

Highly Efficient Co2 Capture With Simultaneous Iron And

Other Applications in Iron and Steel Making Thakur and Das 4 have described several miscellaneous uses of red mud in iron and steel making.

Process For Extraction Of Platinum Group Metals From

A process for treating chromite-bearing ores to obtain useful mineral values especially platinum group metal therefrom wherein the ore is separated into magnetic and non-magnetic fractions the non-magnetic fraction containing a substantial portion of the platinum group metals is concentrated and smelted to produce a metal layer containing platinum group metals and the platinum group .

Steel Electricarc Steelmaking Britannica

Steel - Steel - Electric-arc steelmaking About one-quarter of the worlds steel is produced by the electric-arc method which uses high-current electric arcs to melt steel scrap and convert it into liquid steel of a specified chemical composition and temperature. External arc heating permits better thermal control than does the basic oxygen process in which heating is accomplished by the .

Utilization Of Waste Copper Slag To Produce Directly

Waste copper slag is a refractory material with high iron content but it is difficult to recovery iron minerals from the slag because the iron mainly occurs in fayalite. A new technology of coal-based direct reduction-magnetic separation process was developed to recover iron from the slag assaying 39.85 Fe total and 0.33 Cu.
