Valorization of BOF Steel Slag by Reduction and Phase ...

2017-03-20· Basic oxygen furnace (BOF) steel slag is a main byproduct in steelmaking, and its valorization is therefore of considerable interest, from a metal-recovery perspective and from a residue-utilization perspective. In the present study, the carbothermic reduction of BOF slag was investigated systematically. The reductions of Fe- and P-containing phases (i.e., oxide and compounds) are …

Improving Copper Recovery from Production Slags by ...

With the existing process route in the pyrometallurgy of copper the recovery of valuable metals from the slag phase is not sufficient. The selective separation or enrichment of these metals into a metallic or matte phase would lead to an improved exploitation of the available potential. Beside economic reasons also ecological benefits would be given. While the metallic or matte phase can be ...

Control of Slag and Insoluble Buildup in Ladles, Melting ...

ductile iron production has experienced continued growth, the quality of metallic scrap and other iron-unit feed stocks has steadily deteriorated. The result: slag related melting problems have become widespread issues in recent years. Yet, a search of the foundry technical literature from the past 30 years about slag control and buildup will result in only a handful of articles. A new flux ...

Recovery of base metals and PGMs in a DC alloy-smelting ...

Base metals and platinum group metals can be collected in metallic alloy form, via a wide variety of smelting processes. The recovery, or degree of collection, of the valuable metals is a function of the extent of reduction in the furnace, which, in turn, is indicated by the fraction of iron present in the feed materials that reports to the alloy. An equation has been developed that relates ...

Recovery of metal values from copper slags by flotation ...

The recovery of copper and cobalt from ancient copper slags from the Küre region of Turkey was investigated. A fayalitic-type of ancient copper slag containing 1.24% Cu, 0.53% Co and 53.16% Fe were subjected to an experimental study. Two different routes were followed to recover the metal values. The first route was roasting the slag with pyrite followed by leaching.

Recovery of Titanium from Blast Furnace Slag | Industrial ...

Titanium is one of the most valuable elements found in blast furnace slag, with a concentration of approximate 2.7%.

Slag - Wikipedia

Slag is the glass-like by-product left over after a desired metal has been separated (i.e., smelted) from its raw ore. Slag is usually a mixture of metal oxides and silicon dioxide. However, slags can contain metal sulfides and elemental metals. While slags are generally used to remove waste in metal smelting, they can also serve other purposes, such as assisting in the temperature control of ...
