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 .
pH Due to the effects of the limestone it contains, the pH of iron and steel slag increases to 10 – 12 when it reacts with water, indicating alkalinity that is the same or lower than that of recycled concrete base course material and cementstabilized soil.
Roughly BOF slag, EAF slag and SMP slag can be defined as steel slags. Reviewing the past, utilization of ironmaking slag has a long history. The broken slag from ironmaking was already REUTER, M., XIAO, Y., and BOIN, U. Recycling and environmental issues of metallurgical slags and salt fluxes. VII International Conference on Molten
A process for recovering iron from preliminarily decopperized molten copper smelter slags having an initial composition which includes iron oxide, silica, and aluminum oxide as the major constituents. These constituents are initially present in the range of 4070 percent FeO, 2540 percent SiO 2 and 510 percent Al 2 O 3 . The slag is maintained in a molten state and a solid reductant is mixed ...

Aug 14, 2019· Iron recovery to the pig iron product was in excess of 95%, this was achieved with coreduction of V to the metal in excess of 80% recovery. These slags were subsequently exposed to .
They usually contain a quantity of valuable metals except for BF slag. Recovery of metals from the slags and uitilization of the slags not only can save metal resource, but also can protect the environment. (2) Ferrous slags mainly include iron slag, steel slag, alloy steel slag and ferroalloy slag.
Recovery of cobalt, nickel, and copper from slags, using . Mintek has been working on the recovery of cobalt, and the associated valuable metals, from slags, since 1988, using DCarc furnace technology to effect selective carbothermic reduction of the oxides of cobalt, nickel, copper, (and zinc, where present), while retaining the maximum possible quantity of iron as oxide in the slag.
While it has long been known that substantial quantities of iron have been lost through the discarding of slags (, copper smelter slags), the lack of an economical recovery process, as compared to other sources of iron, has prevented the commercial acceptance of iron recovery from such slags.
temperature, slag basicity, and magnetic field strength on recovery and grade of the concentrate were investigated and optimized oxidation of iron monooxide (FeO) to magnetite (Fe 3 O 4) and other spinel ferrites in RO phase was observed. Solid state oxidation achieved overall optimum
The above patent describes a method that subjects a powered slag is subjected to magnetic separation according particle size to recover iron from the slag, thereby increasing the iron recovery rate, but does not teach any treatment large amounts of iron components contained in an amorphous state in the waste nonferrous slag.

minerals research, inc. (MRI) Our company has extensive experience in the production and marketing of mineral and mineral slag products including: air blasting abrasives (SHARPSHOT® iron silicate), slurry blasting abrasives, roofing granules, roofing backing sands, cement additives, road and roof asphalt fillers, and aggregates.
A method was proposed to recover iron from BOF slag and enhance reactivity of the residue as supplementary cementitious materials. • Additives were optimized to recover iron from BOF slag and the recovery efficiency was more than 95%. • By replacing 30% mass of cement with residue, the compressive strength of the mortar can reach MPa.
Iron and steel slags are coproducts of iron and steel manufacturing. In the production of iron, the blast furnace is charged with iron ore, fluxing agents, usually limestone and dolomite, and coke as fuel and the reducing agent. The iron ore is a mixture of iron oxides, silica, and alumina.
Jul 28, 2016· Abstract. Steelmaking slags are usually processed for iron recovery by dry magnetic separation. The recovered ironrich products are recycled back into the ironmaking and steelmaking processes to replace highcost steel scrap and iron ores.
The slags were cooled down at two different cooling rates (see Fig. 1). Subsequently, the leaching behaviour of selected rare earth elements (Sc, Y, La, Nd) by highpressure acid leaching of the slag was analysed. Firstly, the REEs recovery by acid leaching of a slag with the highest content of aluminium, silicon and iron was studied.
Recovery of Copper and Cobalt from Copper Slags as Selective 389 intervals. By treatment with hot water, recovery of copper and cobalt from the ore mixture was aimed selectively. 2.
