lead processing - lead processing - Mining and concentrating: Once the ore is removed from veins (narrow channels) or lodes (roughly spherical deposits) in the Earth, usually at depths of about 60 metres, the ore is treated at concentrating mills. Here the ore is finely crushed, sometimes to particle diameters of less than 0.1 millimetre (0.004 inch), and then treated by one of several mineral ...
The more uniform sintering process has yielded cost savings by helping to increase the volume of sinter going to the blast furnace, lowered the return fines of the sinter, and reduced fuel consumption. Overall, HKM saw a return on investment in less than a year – an important factor when iron ore prices are problematic.
Iron ore is a natural material that is mined all around the world. Iron ore fines are created as a result of mining, crushing and processing the larger pieces of ore. Iron ore fines are less desirable (and of lower value) as they need to be sintered before they can be utilised, otherwise it will effectively smother the air flow in the blast ...
