Coal FA silica fume ground granulated blast-furnace slag and metakaolin are well-known SCMs . Coal FA is a great example. The American Coal Ash Association reported that approximately 38.2 million tons of coal FA is produced annually in the U.S. and half of the total coal FA approximately 19.2 million tons is reused in cement/concrete appli ions 139 .
The ore is loaded into a blast furnace along with measured quantities of coke and limestone. Hot combustion air is supplied to the furnace and some form of fuel used to raise the temperature. The iron is reduced from the ore by carbon in the coke the limestone aiding slag separation from the molten iron.
Once the mining and transporting is done the ore is crushed to a consistent gravel or golf ball-size the crushed ore is piled into a heap on top of an impenetrable layer on a slight slope. The leaching reagent- dilute sulphuric acid is sprayed through sprinklers on top of the heap pile and allowed to trickle down through the heap dissolving the copper from the ore.
