Waste slag as alternative raw material in the ALF CEMINDFerro Alloys CRONIMET Mining

Waste slag as alternative raw material in the cement production Ferrous slag is produced by adding slagging agents such as limestone or dolomite and/or fluxing materials to blast furnaces and steel furnaces to strip the impurities from iron ore steel scrap and other iron or steel input feedsCRONIMET Mining Processing seeks to prevent the wastage of any valuable metals due to inefficient processing methods and the failure to beneficiate waste material Therefore we use the most advanced technology and processing methods to extract value from ferrochrome ferromanganese and ferronickel slags The slag material typically contains between 15 and 12 metal which once recovered will

Waste Materials Used in Concrete Manufacturing ScienceDirectUG Mat Steel Slag Recycled Materials Resource Center

Red mud and phosphogypsum belong to the family of wastes produced in large quantities like blast furnace slag BF slag fly ash or municipal waste incineration ash MWA Red mud is a residue obtained by the Bayer process during the manufacture of alumina Phosphogypsum is a byproduct from the production of phosphoric acid by the wet process In spite of many possible venues for utilization This nonmetallic slag material can either be crushed and screened for aggregate use steel slag aggregates or sintered and recycled as flux material in the iron and steel furnac Steel slag aggregates generally exhibit a propensity to expand

PDF Solid wastes generation in steel industry and their Slag From By product to Valuable Construction Material

Proper reuse and recycling the entire solid waste generated in steel manufacturing process can meet the demand of a potential resource for fulfilling growing shortages of energy and materials In Recycling slag minimizes waste and disposal costs reduces energy use extends furnace life and lowers the amount of additives needed to make slag The concerns with slag recycling are that first because slag can contain environmentally hazardous materials it must be analyzed for elemental composition before reuse
