Studies on the direct reduction of carbonbearing pellets made from discarded copper slag have been conducted in this paper. They include the influences of reduction coal content, limestone content, industrial sodium carbonate content, reduction temperature, reduction time and layers of carbonbearing pellets on reduction effect. Finally, the optimum conditions have been obtained.
Abstract: For utilize the solid waste synthetically, the cascade grinding technology was used to product cementitious materials with steel slag (SS), iron ore tailings (IOT) and granulated blast furnace slag (GBFS). The effect of SS content and curing process on compressive strength of the high performance concrete (HPC) were investigated, and ...
iron processing, use of a smelting process to turn the ore into a form from which products can be in this article also is a discussion of the mining of iron and of its preparation for smelting. Iron (Fe) is a relatively dense metal with a silvery white appearance and distinctive magnetic properties. It constitutes 5 percent by weight of the Earth's crust, and it is the ...
Meanwhile, with finer of iron tailing and carbide slag, the compressive strength of HCSAAC were improve by 8–13%. Attributed to the nonhydration heat carbide slag, mix grinding technique was conducted to promote grinding efficient and improve compressive strength of HCSAAC, which increased by – MPa than conventional divided grinding.
iron slag grinding for cement. ... (PDF) EFFECT OF PARTIAL REPLACEMENT OF SAND BY IRON SLAG ... Iron and steel making slag are by products of the iron making and steelmaking processes. To date, these types of slag have been widely used in cement and as aggregate for civil works. The report presents an investigation of mechanical and durability ...
The primary components of iron and steel slag are limestone (CaO) and silica (SiO 2).Other components of blast furnace slag include alumina (Alsub>2 O 3) and magnesium oxide (MgO), as well as a small amount of sulfur (S), while steelmaking slag contains iron oxide (FeO) and magnesium oxide (MgO).In the case of steelmaking slag, the slag contains metal elements (such as iron) in oxide form ...
Kobe Steel has developed the ITmk3 ® Process, which produces highpurity granular iron by utilizing iron ore concentrate and noncoking coal. The ITmk3 ® Process is distinctive with reduction, carburizing, melting and slag separation occurring promptly at lower temperature. The ITmk3 ® Process completely bucks conventional concepts of ironmaking. Kobe Steel regards it as the third ...
Feb 17, 2016 · Slag grinding with the vertical Roller Mill in China() News Date: 09:48:53. Granulated blast furnace slag has been used as a component of blast furnace cement for many years. The replacement of a certain clinker portion by blast furnace slag saves raw materials and thermal energy for pyroprocessing.
C22B15/00. 1. A process for the recovery of iron from copper slag which comprises: i. selecting and grinding the copper slag to [the] a size in the range of 215 mm. ii. mixing homogeneously copper slag, a reductant and a flux in the ratio range between 20:1:4 to 20:3:10. iii.
Apr 04, 2012 · Unlike the iron slag, the steel slag exhibits much lower hydration reactivity and poorer hydraulic properties. Furthermore, it usually contains high content of freeCaO and periclase, which can produce excessive volume expansion as a result of hydration and therefore induce volume instability. In addition, the grinding of steel slag is energy ...
