Subject category Comment text
Deposit DEPOSITS MAY BE OFFSET BY FAULTING. ABOVE FIGURES ARE FOR LARGEST BODY OF ORE. MN IN VEINS FOLLOW FAULTS.
Deposit RESULTS OF U.S. BUREAU MINES ORE DRESSING TESTS SHOWED NO APPRECIABLE LIBERATION OF IRON OXIDES COULD BE MADE IN FEASIBLE GRINDING RANGES BECAUSE OF COMPLEX ASSOCIATION OF MANGANESE AND IRON OXIDES. THUS TABLING, MN FLOTATION AND MAGNETIC SEPARATION PRODUCE NO MARKETABLE MN. HOWEVER, ORE WHICH CONTAINS 19.9 PCT. MN AND 35.8 PCT. FE IS VERY LOW IN OBJECTIONABLE IMPURITIES AND MIGHT BE MARKETABLE AS SPIEGELEISEN ORE. ; INFO.SRC : 1 PUB LIT
