Research on Phosphorus (P) removal capacity by blast furnace slags (BFS) has been undertaken in Sweden for the last decade. Both laboratory experiments and field trials have been carried out. While laboratory investigations revealed that BFS has a high Psorption capacity (95–), P removal in field trials was much lower, ranging from 40 to 53%.
Jul 03, 2015· Blast furnace slag is a byproduct from blast furnaces which is used to produce iron.

Blast Furnace Slag Material Description ORIGIN In the production of iron, iron ore, iron scrap, and fluxes (limestone and/or dolomite) are charged into a blast furnace along with coke for fuel. The coke is combusted to produce carbon monoxide, which reduces the iron ore to a molten iron product.
Disposal. While most of the furnace slag is recycled for use as an aggregate, excess steel slag from other operations (raker, ladle, clean out, or pit slag) is usually sent to landfills for disposal. MARKET SOURCES. Steel slag can normally be obtained from slag processors who collect the slag .
HOW A BLAST FURNACE WORKS Introduction The purpose of a blast furnace is to chemically reduce and physically convert iron oxides into liquid iron called "hot metal". The blast furnace is a huge, steel stack lined with refractory brick, where iron ore, coke and limestone are dumped into the top, and preheated air is blown into the bottom.
May 09, 2018· Ground Granulated Blast Furnace Slag (GGBS) The importance of Ground Granulated Blast Furnace Slag (GGBS) lies in its greener way to become a substitute in concrete material. GGBS being a waste material, it needs proper method for disposal. So incorporating this waste material in concrete can reduce the depletion of conventional concrete components such as cement, fine .

In the latest technological solution to a decades old problem, researchers have determined that using blast furnace slag through a process called vitrification, can reduce the volume of radioactive material by 90%. This astounding breakthrough in nuclear fuel disposal melts waste down into little cubes of glass making it way easier to dispose of.
While substitution of ground granulated blastfurnace slag for up to 70% of the portland cement in a mix has been used, there appears to be an optimum substitution percentage that produces the greatest 28day strength. This is typically 50% of the total cementitious material but depends on the grade of ground granulated blastfurnace slag used.
Blast furnace slag (BFS, see Wikipedia ground granulated blastfurnace slag) is a nonmetallic byproduct of the manufacture of pig iron in a blast furnace. BFS consists primarily of silicates, aluminosilicates, and calciumaluminasilicates.
Granulated blastfurnace slag is a coproduct of the steel industry produced by adding a limestone flux to the ore to remove nonferrous contaminants. As such, it may contain small quantities of hazardous heavy metals, including trace amounts of chromium, usually in solution in the glass.
Abstract: A large amount of solid waste slag is generated in the production process in iron and steel enterprises. As for enterprise which takes blast furnace as the process, blast furnace slag accounts for more than 50%. Blast furnace slag disposal has experienced the following development: as a waste treatment, use in subgrade and foundation engineering, to the stage of comprehensive ...
The slag can also be used to create fibers used as an insulation material called slag wool. Basic slag. Basic slag is a coproduct of steelmaking, and is typically produced either through the blast furnace oxygen converter route or the electric arc furnace ladle furnace route.
