Features of The Processes of Clinker Formation When Using Solid Waste From Caprolactic Production As A Mineralizer

The possibility of using a soda-sulfate mixture - an alkaline waste from the production of caprolactam, as a mineralizing additive in a Portland cement raw mixture containing, as a silica-containing component, flotation tailings of the lead-concentrating plant of Almalyk MMC, has been studied. The effect of this additive on the processes of mineral formation during the synthesis of Portland cement clinker is shown. The possibility of additional recovery of residual non-ferrous metals - lead and copper - by sublimation and trapping of their chlorides has been established.
