This advanced metallic recovery allows for the recovery of virtually all residual metallics from the slag, maximizing recovered iron units. the processing plants include the latest technology in screen design to cleanly separate the slag and scrap into different sized fractions depending on customer specifications and market demand.
Studies on the direct reduction of carbon-bearing 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 carbon-bearing pellets on reduction effect. finally, the optimum conditions have been obtained.
These metal recovery plants are used to recover the entrapped metal ferrochrome from the slag generated during the production of ferro chrome and charge chrome. the slag, which has a metallic content of approximately 4 percent, is passed through crushing units
The danieli group has been concerned with the environmental issues related to the steel production cycle for more than 40 years. in keeping with an international commitment to encourage recycling, recovery and re-use of waste materials, and with a constant environmental awareness, danieli environment has developed new technological solutions enabling slag reutilization.
Apr 12, 2013nbsp018332issues connected with steelmaking slag. expansion of steelmaking slag lime cao and other minerals are used as the flux for steel refining. since the melting point of pure lime is as high as 2,572 deg c, it does not melt during the steelmaking in bof
