Iron ore was won by drilling and blasting (Figure 7.1).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 …

The iron in the chalcopyrite ends up converted into an iron(II) silicate slag which is removed. Most of the sulfur in the chalcopyrite turns into sulfur dioxide gas. This is used to make sulfuric acid via the Contact Process. An overall equation for this series of steps is: [2CuFeS_2 + 2SiO_2 +4O_2 rightarrow Cu_2S + 2FeSiO_3 + 3SO_2 label{1} ]
