1. Ground Granulated Blast Furnace Slag Ground Granulated Blast Furnace Slag (GGBFS) is a by product of the steel industry. Blast furnace slag is defined as “the non-metallic product consisting essentially of calcium silicates and other bases that is developed in a molten condition simultaneously with iron in a blast furnace.” [1] In the production of iron, blast furnaces are loaded with iron o...

Thionocarbamates are the group of collectors that mostly used for flotation sulphide copper minerals, alone or in combination with xanthates depending on a mineralogical composition ore. In this paper, results study application thionocarbamates slag presented. Chemical analysis smelter sample obtained from Flotation plant Bor, Serbia, showed it contains 3.56% copper, which over 73% is form, as ...

In order to maximize the utilization value of copper slag, a process smelting copper–iron alloy with slag is proposed here. The reduction kinetics by H2 are studied in this paper. main phases were Fe2SiO4 and Fe3O4. suitable conditions temperature 1373.15 K, partial pressure 40%, calcium oxide addition amount 30%. these conditions, metal ratio was 85.12%. after reduction, heated 1773.15 K for 4...

EPA has completed a substantial study to re-evaluate use of the presence of slag wool fibers as a potential marker for World Trade Center (WTC)-derived dust contamination. Slag wool is an insulating material (made from blast furnace slag) that was used in the construction of the WTC. Large quantities of slag wool were released into lower Manhattan by the collapse of the WTC. Samples of dust col...

Due to the extremely large global production and utilization of concrete, concrete industry is considered a consumer energy natural resources one main sources greenhouse emissions waste generation. Reducing its impacts on environment most important paths toward sustainable construction development. Replacing cement aggregates with byproducts from other industries possible way achieving this goa...
