Application of magnetic separation to steelmaking slags
Steel making slag is produced from basic oxygen furnace (BOF steel slag) and electric arc furnace (EAF steel slag) in the steel making process. They comprise In the literature, such a kind of comprehensive study is rare.

Recycling and utilization of calcium carbide slag
Coal is the dominant fuel in China to provide primary energy, and 70% of polyvinyl chloride is produced from coal-based CaC 2.CaC 2 reacts with water to produce acetylene and calcium carbide slag (CCS) as a solid waste for polyvinyl chloride production. Approximate 40 million tons of dry CCS are generated annually in China, among which These different types are referred to as furnace or tap slag, raker slag, synthetic or ladle slags, and pit or cleanout slag. Figure 18-1 presents a diagram of the general flow and production of different slags in a modern steel plant. The steel slag produced during the primary stage of steel production is referred to as furnace slag or tap Steel Slag Material Description User Guidelines for Waste

This slag contains indeed about 30 wt.% Fe and 2.5 wt.% Cr. However, the minerals are intergrown at small scale (<100 µm) and iron and chromium are mostly contained in spinel phases which makes Minerals Free Full-Text Characterization of a Chromium-Bearing

Optimization of magnetic separation process for iron
To improve the efficiency of iron recovery from steel slag and reduce the wear-and-tear on facilities, a new method was proposed by adding a secondary screen sizer to the magnetic separation process according to grain size distribution of magnetic iron (M-Fe) in the slag. The final recycling efficiency was evaluated by calculating the percentage The cross-belt magnetic separator, drum magnetic separator and magnetic pulley separator are usually-used. The work results reported by ( Fregeau-Wu et al., 1993 ) show that phosphorus in steel slag occurs predominantly in di-calcium silicate and to a lesser extent in di-calcium ferrite in solid solution.Recovery of high grade iron compounds from LD slag by enhanced magnetic

The magnetic particles (grinding media) were removed by magnetic separation using a SALA low-intensity magnetic separator (Mortsell separator). The subsample of the ground slag sample was remelted to settle and separate Cu-containing inclusions in a Nernst-Tammann carbon-resistance furnace supplied by Ruhstrat K.G.Low intensity separators employ either electromagnets or permanent magnets. Electromagnets provide relatively high magnetic strengths. Separators are also made in the form of drums, magnetic drums.They have five poles symmetrical about the centerline of the magnetic yoke, with the poles alternating,which helps to improve the agitation at the Magnetic Drum an overview ScienceDirect Topics
