Slag WikipediaChemical Composition of Samples Collected from Waste
Slag is the glass like by product left over after a desired metal has been separated ie smelted from its raw oreSlag is usually a mixture of metal oxides and silicon dioxideHowever 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 Thirty one samples collected for geochemical analysis were obtained from waste rock dumps 25 stockpiles or mill shale piles 3 tailings 1 slag 1 and outcrop 1 from 20 mines and prospects Waste rock dump stockpiles or mill shales and tailings samples were collected as

GENERAL INFORMATION Iron Steel Slags about NSA IRON Recycled glass as a partial replacement for fine aggregate
The chemical composition of slag from a given source and therefore its mineralogic composition varies within It is important that steel slag used in construction is obtained from a producer who has a quality control program in place Removal of contaminants from waste water is a new and potentially important application for steel 222 Waste Glass Waste glass for this experiment was sourced from a glass recycling company in the Sydney region The company collects mixed colour post consumer con tainer glass before subjecting the material to a crushing and milling process in order to create a fine aggregate The typical chemical composition of the
