A method of making cement from base metal smelter slag produced by a nickel copper lead or zinc smelter includes crushing the slag with a source of calcium sulphate to a size of less than about 1/4 inch and heating the mixture to produce a cement and grinding the cement to a size in the range of from about 250 to about 425 meshThe blast air causes the iron oxides flux and coke to react and iron carbon monoxide and blast furnace slag is produced The molten iron and blast furnace slag is collected at the base of the furnace while the gases are recirculated for fuel in the sinter process after separation of particulate material Cooper
