The Thacker Pass Mine is Indeed Benign, Compared to

2021-7-20  Gold mines often have strip ratios of waste to ore that are large- often well over 5 tons of waste to 1 ton of ore. The Thacker Pass mine will have a waste to ore ratio that is 1.6 tons of waste to 1 ton of ore. This low waste to ore ratio will reduce the size of the pit correspondingly, since much of the material removed from the pit will be ore.

Iron ore extraction techniques - ScienceDirect

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 progressed to the dip, this ...
