A process for producing metal ore pellets from a particulate carbon-based material, a metal ore material, and a silicate-based binder which includes one or more surfactants, comprising the steps of admixing the materials and binder, and agglomerating the so-formed mixture by tumbling to form the pellets at ambient temperature. The tumbling action, such as in a rotary drum, serves to agglomerate the particles and bind the mixture into the pellets. No mechanical compression force is required. The process provides a simple but efficient process for using waste carbon-based materials and waste metal ore materials, and forming a useable product, which is ready for smelting. Rotating drum or pan agglomerators are relatively low cost to build, and are capable of very high tonnage throughputs. |
