Types of Mining Methods | Sell Side Handbook

2018/03/11 · Long-hole sublevel stoping, often referred to as sublevel open stoping and blast hole stoping is a commonly used method in large scale mining. It is a versatile and productive method that is primarily used for large ore bodies with a steep dip, regular shape, and defined ore bodies. It is used when the ore body is narrow in width (6-30 metres).

Iron ore extraction techniques - ScienceDirect

2015/01/01 · DSOs, when mined, typically have iron (Fe) content of between 56% and 64% Fe. By comparison, magnetite ore typically has a much lower iron content of between 25% and 40% Fe and in this form is unsuitable for steel making. The main iron mineral in magnetite ore is the ferrous iron oxide magnetite (Fe3 O 4 ).
