The processing of iron ore requires physical processes that help ensure conformation to sizing specifications and where required help the ore achieve grade targets. The sizing separation of iron ore is achieved through the comminution and screening processes described in Chapter 8. This chapter is concerned with the further physical separation processes applied to both coarse and fine portions of comminuted iron ore …… Read more

Jan 01, 2015 · 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 roof …… Read more
