Leaching of heavy metals from steelmaking slags

Cementitious Properties of Steelmaking Slags

Utilization of ironmaking and steelmaking slags

smelting of hammerable iron and its treatment in antiquity and Medieval produced also by-product: slag. Because of small yields of iron the process produced only small amounts of slag that did not attract attention of smelters concerning its possible use. the use of slag pieces was only accidental. a lot of slag pieces and blocks from slag pit shaft furnaces were used as a material for mound bu...

Leaching of heavy metals from dredged bottom sediments

Deposition of sediments on land in atmospheric conditions causes many risks connected with environmental protection. Particularly dangerous is leaching of heavy metals from sediments deposited on land The research aimed at assessment of leaching of heavy metals from dredged bottom sediments potentially disposed on land. In this research it has been shown that the leaching of heavy metals during...

Feasibility of recovering metals from associated slags

The associated mineral ore accompanying Valuable Metal Compounds (VMC) have been usually treated in a smelting furnace ,such as Blast Furnace, Reverberatory, Blowing Furnace, hence the VMC were mostly concentrated into the molten associated slags and separated from liquid metals. So the associated slags become an important man-made resources (Table I), in which the VMC exist dispersively in var...

Elution of Metals from Fused Slags Produced from General Garbage

Many industrial products that would traditionally be disposed of are now being recycled to reduce environmental pollution and conserve resources. Various techniques for the recovery, processing, and reuse of materials have been developed. Recently, the safety of reusing such materials has been investigated. Waste materials such as city garbage are generated in great quantities. In Japan, most g...
