Harsco Metals & Minerals services

Harsco has developed a cost-effective closed-loop process to achieve an environmentally controlled solution that meets the requirements of environmental protection authorities.

Harsco"s innovative solution to green foundry sand waste uses a unique separation process to produce clean sand and an anthracite/bentonite residue.

Many integrated steelmakers recycle their particulate by-products to the sinter plant. However, because of the low volume and poor handling characteristics of the materials, this often results in variations in the composition and homogeneity of the sinter bed with implications for sinter plant productivity.

Harsco provides a range of solutions for recycling slag. We process Blast Furnace slag, Converter slag and Ladle slag, to meet the specific chemical, mechanical and physical properties required of the final recycled product. We also comply with local environmental regulations.

Harsco specializes in recovering metallic units from by-products, through processing metals industry by-product materials in purpose-built metal recovery plants.

Full solution for recycling of hazardous spent potliners.

Harsco processes a range of ferroalloy slags (Ferrochrome, Ferromanganese) to recover the metals and recycle the residuals. The slag material is fed into a metal recovery plant, and goes through crushing and jigging phases. We adapt the process to the material being treated, using our know-how in handling ferroalloy slags. Harsco will deliver metallic units to the specified metal grade. The recovered metallic units are or sold on the open market, or returned to the customer for re-use in production. Commercial arrangements with customers are tailored to the needs of each contract. The residual aggregate is processed to a size fraction for the intended application (e.g. concrete).
