recovery iron slag

Using Ca/Mg in the slag to capture and store the CO 2 via mineral carbonation is a promising approach to the reduction of waste emissions Since iron– and steelmaking slags are a mixture of numerous types of minerals understanding the dissolution behavior of various phases in solution system is of critical importance for Ca/Mg recovery

Recovery of Iron from Lead Slag with Coal

Iron recovery from a lead slag in Henan province was carried out with the technique of coal-based direct reduction followed by magnetic separation Scanning electron microscopy (SEM) was used to investigate the transformation of iron-containing minerals and the particle size of metallic iron

settled in the slag cannot be effectively utilized Main methods in use for iron recovery from copper slag include direct beneficiation for iron recovery [3] oxidative modification [4 5] of iron oxide for iron recovery smelting reduction for iron recovery [6 7] and direct reduction (DR) for iron recovery

RECOVERY OF PIG IRON FROM COPPER SMELTING SLAG BY REDUCTION SMELTING Copper slag is a by-product obtained during smelting and refining of copper Copper smelting slag typically contains about 1 wt % copper and 40 wt % iron depending upon the initial ore quality and the furnace type Main components of copper slag are iron oxide and silica

Slag Heat Recovery

In modern blast furnaces around 0 25-0 30 tons of liquid slag with a temperature of approximately 1450C are produced per ton of pig iron A number of slag heat recovery systems have been proposed However none have yet been applied commercially due to technical difficulties that arise in the development of a safe reliable and energy-efficient system

P is unevenly distributed in steelmaking slag and generally concentrated in the 2CaO・SiO 2 phase as a 2CaO・SiO 2-3CaO・P 2 O 5 solid solution This evidence reveals the potential to separate P from steelmaking slag In this chapter various technologies for P separation and recovery from steelmaking slag are described

The kinetic behavior of Cr 2 O 3 reduction by iron melts containing carbon aluminum and silicon were investigated at various conditions in order to understand effective slag treatment for recovery of chromium from stainless slag It was found that the recovery rate of chromium was fairly slow but it was considerably accelerated by the addition of some fluxes such as Al 2 O 3 and SiO 2 to

Recovery of Chromium from Ferrochrome Slag Recovery of chromium from ferrochrome slag is 64% by treatment of slag with lime at 973K in solid phase The soluble chromium ion was extracted with water The chromium from liquid extract is separated with fly ash based zeolite which has 3000 mmol/gram and it can be regenerated to recover chromium REFERENCES 1

leach slag It was deduced that roasting prior to leaching was essential to ensure that the manganese was converted into a soluble form A manganese recovery of 82% was achieved in 2 hours at a temperature of 80˚C The oxidation of sucrose however increased the rate of leaching yielding an 86% recovery in 1 hour The pregnant leach solution

manganese loss into steelmaking slag is almost equivalent to that of manganese input into steelmaking process as ferro-manganese etc in both countries The results of material flow analysis suggest that a significant ripple effect can be expected if the recovery of manganese and phosphorus from iron- and steel-making slag becomes possible 3
