Reducing the carbon intensity of the iron making value

"The iron ore agglomerates, can then be charged into a blast furnace along with the metallurgical coke to separate the metal from the gangue avoiding the sintering process." Vining said. As there is less waste material to melt, there would also be less metallurgical coke needed in the furnace per tonne of iron metal.

HOW A BLAST FURNACE WORKS

The iron ore, pellets and sinter then become the liquid iron produced in the blast furnace with any of their remaining impurities going to the liquid slag. The coke is produced from a mixture of coals. The coal is crushed and ground into a powder and then charged into an oven. As the oven is heated the coal is cooked so most of the volatile matter such as oil and tar are removed. …

Types of Mining Methods

 · Ore is blasted in its lower portion to begin with, but after that, the rock is mostly broken under the stresses of its own mass. Since minimal blasting is required once production begins, operating costs for block caving are generally lower than that of other mining methods, ranging from $-$5/tonne. Some block caving operations have mining
