Open-pit – 90% of ore is mined using the open pit method. Ores near the surface can be quarried after removal of the surface layers. The ore An ore is a rock that contains enough metal to make it worthwhile extracting. Grinding The ore is crushed, then ground into powder. Concentrating The ore is enriched using a process called froth flotation.
What are the different types of mining and how do they differ?
Underground Mining. Underground or Sub-surface mining involves the digging of a network of shafts and tunnels into the earth to reach and extract the deposit of ore or mineral beneath the earth. In comparison to other methods, underground mines impact less on the environment and are much more harmful to those working within them.
Ore sorting: Efficiently optimise the treatment of ores in ...
By using ore sorting equipment, ore concentrates can be created at very low cost in small or remote mining installations. The entire processing line can be planned in semi-mobile form and consists only of crushers, screens, belts and sorting machines. This allows immense cost savings for transport, since the waste rock is disposed of on-site.
