The steelmaker benefits from slag recycling by avoiding the cost of landfill. The community benefits, too. Slag is a man-made mineral, therefore its use as an aggregate in place of a natural aggregate product avoids the …

 · The environmental concerns that have became apparent in the last couple decades have pushed researchers to rethink what this hazardous waste is doing to the environment and how to deal with it. In the past, slag was taken from the blast furnace, basic oxygen furnace (BOF), and electric arc furnace (EAF) and hauled off to a hazardous …

Environmental Science and Pollution Research. 2014. TLDR. It is suggested that recycled Ni smelter slag could be an effective low-cost reactive medium for a subsurface remediation system, such as a permeable reactive barrier, for arsenic removal from aqueous solutions.

 · The main function of these two types of slag is to remove the useless or harmful substances in the raw materials from the metal products. There is another type of slag whose main function is to enrich certain useful substances contained in the raw materials in order to facilitate recycling them in the next process.

 · In addition, the slag samples from the melting tests were leached and analyzed to evaluate the behavior of carbon containing scrap. The elevated carbon content in the scrap resulted in more carbide formation in salt slags and thus more methane generation in salt slag recycling with a higher environmental impact.

In this research, an innovative method to recycle lithium from pyro-slag by evaporation during chlorination roasting was proposed. Different chlorine donors, namely NaCl, AlCl 3, and CaCl 2 were evaluated by HSC software and experiments, among which CaCl 2 possessed a stronger ability of chlorine donation in the chlorination roasting process.
