The "ORLA" research project is attempting to evaluate the pathways and limitations of recycling steelworks slag through sequential physical sorting. The objective was to concentrate two distinct fractions; one comprising the iron-bearing slag for intra-steelworks recycling, and the other the calcium- and calc-silicate-bearing slag for cement-plant recycling.
