Jo Van Caneghem – KU Leuven. Leaching of heavy metals from concrete pavers containing wastetoenergy bottom ash as an aggregate
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 ...

microstructure of the slag. This paper reviews existing and novel routes for metal recovery and fayalite slag utilization. Keywords: slags, fayalite, microstructure, nonferrous metals recovery, utilization, leaching Abstract In order to achieve full valorization of the slag, the combination of the two schemes is worthwhile to be considered.
Recovery of Iron from Copper Flash Smelting Slags Figure 3 shows the rapid decreasing of copper content in the slag during the first 15 minutes with the graphite rod introduced into the melt, while the iron concentration is maintained almost constant over same period of time, suggesting that a selective reduction
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.
We investigated the effect of flux (lime) addition on the reduction behavior of iron oxide in copper slag by solid carbon at 1773 K (1500 °C). In particular, we quantified the recovery of iron by performing typical kinetic analysis and considering slag ing, which is strongly affected by the thermophysical properties of slags. The iron oxide in the copper slag was consistently reduced by ...
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.

In nature, iron, copper, lead, nickel and other metals are found in impure states called ores, often oxidized and mixed in with silicates of other metals. During smelting, when the ore is exposed to high temperatures, these impurities are separated from the molten metal and can be removed. Slag is the collection of compounds that are removed.
