The grown demand of current and future development of new technologies for high added value and strategic metals, such as molybdenum, vanadium, and chromium, and facing to the depletion of basic primary resources of these metals, the metal extraction and recovery from industrial byproducts and wastes is a promising choice. Slag from the steelmaking sector contains a significant amount of ...
Jan 25, 2021 · EPA finalized the first federal limits on the levels of toxic metals in wastewater that can be discharged from power plants on November 3, 2015. Coal ash, also referred to as coal combustion residuals or CCRs, is produced primarily from the burning of coal in coalfired power plants. Coal ash includes a number of byproducts produced from ...
ASMS is a joint venture between the Cement Australia Group and the Edward C Levy Co (USA) formed in 1989 to service the slaghandling contract at BlueScope Port Kembla NSW. ASMS is contracted to collect and treat molten slag from the blast furnace and the steel making processes. We are responsible for the processing and marketing of approximately million tonnes of slag per year.

A hydrometallurgical process for treating slag material, especially copper smelter slag material, comprises vigorously mixing the slag material with about one part by weight of sulfuric acid and about one part by weight of water for each part by weight of the slag material, and allowing the resulting mixture to react to produce a dry, solid material, containing the metal values of the slag in ...
Jul 11, 2006 · Resource recovery and recycling from millions of tons of wastes produced from industrial activities is a continuing challenge for environmental engineers and researchers. Demand for conservation of resources, reduction in the quantity of waste and sustainable development with environmental control has been growing in every part of the world.
Pyrometallurgical metal production results in side streams, such as dusts and slags, which are carriers of metals, though commonly containing lower metal concentrations compared to the main process stream. In order to improve the circular economy of metals, selective leaching of copper from an intermediate raw material originating from primary base metal production plant was investigated. The ...
