2015-1-1  Iron ore was won by drilling and blasting ().As mining technology generally developed, so did drilling techniques and the explosives used. Smith (1990) reported that the Cleveland deposit was associated with a very strong stone roof rock (known as “dogger”) allowing mine drivages to be self-supporting. However, he states that in later years where the mining had progressed to the dip, this ...

During this paper, in order to identify the priority of consideration between the problems of “mining method selection” and “determining transition depth from open-pit to underground mining” an accurate procedure is introduced step by step. First, it is essential to specify if an ore deposit that potentially will have mined by a combined method of open-pit and underground mining.

2021-10-31  Iron ore is a mineral block found underground. It is a source of raw iron, which can be smelted into iron ingots. Deepslate iron ore is a variant of iron ore that can generate in deepslate and tuff blobs. Iron ore itself can be obtained by mining it with a stone pickaxe or higher enchanted with Silk Touch. When mined without Silk Touch, iron ore drops raw iron

Geology and mining — MineFacts

There are several types of iron ore minerals, magnetite and haematite ore being the most important. In Sweden, most of the iron ore is extracted from so-called apatite iron ore. It takes its name from the high content of apatite mineral, which contains phosphorus. The apatite iron ores in the active mines contain about 70 per cent iron.
