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 …

Normally, the maximum recovery is high with the highest run-of-mine grades and decreases with low grades. Minsur S.A. have defined an updated run-of-mine cut-off of 0.64% Sn for San Rafael. Usually, the plant is operated with an average of 1.9% Sn with a recovery of 93%. The cut-off for ore is also defined is 0.14% Sn.

Iron ore sintering consists of heating a layer of fines until partial melting occurs and individual ore particles fuse together. For this purpose, a traveling-grate machine is used, and the burning of fine coke (known as coke breeze) within the ore generates the necessary heat. Before being delivered to the sinter machine, the ore mixture is ...
