Collections: Iron, How Did They Make It? Part I, Mining

As for the ratio of iron-ore to finished iron, as far as we can tell, ancient iron-working was a lot less efficient than modern iron-working. From raw ore to finished goods, the estimates range from 8-16% of the mass of the ore ends up in the finished product. Not quite enough to explain the discrepancy, but still a big gap from modern …

Mine Planning and Optimisation Techniques Applied in an Iron Ore …

For the iron ore mine, the initial exploration drilling was done on a 100 m × 100 m grid in order to cover the major outcrop. The orebody was found to be complex; therefore, the 100 m × 100 m grid was then reduced to a 50 m × 50 m grid in order to obtain sufficient information below the ground surface.

BlastHole Drilling Introduction

In smaller holes, it is most common in softer rock formations. The drilling principle is to use a high pull down force (weight-on-bit), rotate the drill bit, and blow the rock cuttings to the surface with compressed air. Hardrock drills typically use the Rotary method to drill blastholes from 200 mm (7 7 /8") to 311 mm (12 ¼") diameter.

Iron ore extraction techniques

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 …
