Since 2011, Harsco has supported the plate mill with a range of slag handling and metal recovery services through a Harsco-led joint venture relationship. This latest contract builds on this.
Copper smelting slag is produced from copper pyrometallurgy (both smelting and converting stages), usually grading at 0.3-3%. The slag may also contains lead zinc minerals like galena, sphalerite. Copper mainly dwells in the slag in the form of bornite, chalcocite, chalcopyrite, and metallic copper.
By using DR followed by a magnetic separation process for iron recovery from copper slag, Yang obtained iron powder of 92.05% iron content with an iron recovery rate of 81.01%, and Wang obtained iron powder of 92.96% iron content with an iron recovery rate of 93.49%. Both of their tests have achieved good results.

The SCF slag is processed for copper-cobalt recovery to produce a copper- cobalt-iron alloy in the cobalt recovery furnace (CRF). The CRF process aims to obtain a final slag of approximately 0.4% copper and 0.2% cobalt which is normally discarded. The reductant used in these two processes is coke.
Mintek has been working on the recovery of cobalt, and the associated valuable metals, from slags, since 1988, using DC-arc furnace technology to effect selective carbothermic reduction of the oxides of cobalt, nickel, copper, (and zinc, where present), while retaining
Better durability and reducibility. Conversion — iron and carbon rich fines, dust and wet sludge to high-quality feedstock. Mixing— places fine carbon particles in contact with iron oxide to drive rapid direct reduction. Binder — uses less for more overall material recovery.
recovery of ferrochrome from steelmaking slag - sighri. or in the cement industry, steelmaking slag has high iron content and is The recovery of iron and chromium from contaminated soils will preserve the . ferrochrome, a solid solution of metallic iron and chromium from the reduction of.
leaching to recover manganese from steel plant slag. This investigation showed that treatment of the slag in hydrogen prior to leaching enhanced manganese extraction. Up to 80 pct of the manganese and 50 pct of the iron could be extracted from a silicon steel slag that had been pretreated in hydrogen at 7000 C. Two 4-h leaching stages conducted at ambient temperature with a solution containing ammonia
Nov 14, 2013A technique of copper, zinc, and iron recovery from the slag of the plant was proposed. The mixture of the slag and ammonium chloride (wt ratio 1:2) was treated at 320 C for 120 min and subjected to water leaching. After separation the solid residue was treated with ammonium chloride (wt ratio 1:2) for 160 min.
temperature, slag basicity, and magnetic field strength on recovery and grade of the concentrate were investigated and optimized oxidation of iron mono-oxide (FeO) to magnetite (Fe 3 O 4) and other spinel ferrites in RO phase was observed. Solid state oxidation achieved overall optimum
In addition to slag recovery, the liquid furnace slag and ladle slags are generally processed to recover the ferrous metals. This metals recovery operation (using magnetic separator on conveyor and/or crane electromagnet) is important to the steelmaker as the metals can then be reused within the steel plant as blast furnace feed material for the production of iron.
Fig. 7 shows a proposed process flowsheet for the copper, zinc, and iron recovery from copper smelter slag of Balkhash copper plant. In this process, crushed slag, with ammonium chloride in a weight ratio 1:2 is subjected to heat treatment for 120 min at 320 C.
Iron sulfides were found to extract approximately 45 per cent of the uranium from the slags by a single contact with the slags. Contacting one portion of furnace slag with three successive portions of iron-calcium, bismuth or iron sulfide extractant did not improve the total uranium extraction from the slag to above 50 per cent. Contacting

The blast furnace is the primary means for reducing iron oxides to molten, metallic iron. It is continuously charged with iron oxide sources (ores, pellets, sinter, etc.), flux stone (limestone and dolomite), and fuel (coke). Molten iron collects in the bottom of the furnace and the liquid slag floats on it.
