Roughly BOF slag, EAF slag and SMP slag can be defined as steel slags. Reviewing the past, utilization of ironmaking slag has a long history. The broken slag from ironmaking was already REUTER, M., XIAO, Y., and BOIN, U. Recycling and environmental issues of metallurgical slags and salt fluxes. VII International Conference on Molten
For carbon steel slags: after screening of slag materials our magnetic separation process ensures the highest level of metal recovery. Through further crushing and screening, the scrap can be upgraded to high-Fe material for use as coolant scrap in the mill. The residual slag is sold as an aggregate.

The slag occurs as a molten liquid melt and is a complex solution of silicates and oxides that solidifies upon cooling. Virtually all steel is now made in integrated steel plants using a version of the basic oxygen process or in specialty steel plants (mini-mills) using an electric arc furnace process.
Aluminum Salt Slag Recycling Technology. Ultromex provides patented solutions to the Aluminum Smelting Industry. Our technology is the most effective method for smelters who want in-situ aluminum salt slag recycling & treatment to recover valuable metals and flux salts.
Slag is the glass-like by-product left over after a desired metal has been separated (i.e., smelted) from its raw ore. Slag is usually a mixture of metal oxides and silicon dioxide . However, slags can contain metal sulfides and elemental metals.
The slag recycling process was established in an industrial operation, and consumption of desulfurization flux decreased by 40% with the process compared with that without slag recycling.
Recycling fused slag from the SAW process is economical and environmentally friendly. Submerged arc welding (SAW) slag is recycled by taking the fused part of the slag after welding and processing it in a manner that allows it to be reused for the same SAW operation.
Silicomanganese Slag Recycling Solution. Silicomanganses slag is the by-product during manufacturing the silicomanganese alloy, production of 1KG silicomanganese alloy is accompanied by generation of about 1.2 Kg of ilicomanganese slag.
