Iron Ore Mining Techniques Metal Extraction

2021-7-15  Iron ore mining can be broadly divided into two categories namely 1) manual mining which is employed in small mines and 2) mechanized mining is suitable for large iron ore mines. Manual mining method is normally limited to float ores and small mines. Mining of reef ore is also being done manually on a small scale.

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

Mining is the process of extracting useful materials from the earth. Some examples of substances that are mined include coal, gold, or iron ore.Iron ore is the material from which the metal iron is produced. The process of mining dates back to prehistoric times. Prehistoric people first mined flint, which was ideal for tools and weapons since it breaks into shards with sharp edges.
