Mining was first started in the Tintic District in 1868, since which time there have been great fluctuations in the amount of mineral annually produced, but now as shown by the development of Chief Consolidated, a much better knowledge of the ore deposits have been obtained, and there is also better methods of mining and ore treatment.

How sulfide and taconite mining differ o Desired ore lacks significant sulfur content; the chief ironbearing minerals include iron oxides and iron carbonate o Reaction with air/water = rust o Mining rock waste less likely to produce acid o Ore body contains sulfur o Mining activity can produce acid o Reaction with air/water = H +, SO 4 2 ...
