• Description:
  The Bureau of Mines studies tailings samples from 11 large-scale western copper operations to determine the potential for recovery of rutile and other critical and strategic minerals. Up to 15 pounds per short ton (lb/st) ti02 was found in these samples; however, only 9 to 44 pct of the tio2 was liberated rutile. For one sample, gravity preconcentration, grinding, and flotation recovered 34 pct of the tio2 in a 54.8-Pct-tio2 concentrate. Over 0.38 Lb/st w was found in some of the tailings samples. Scheelite was identified as the major w mineral. Nine of the eleven samples contained about 0.02 to 0.18 Lb/st carbon monoxide Pyrite was the principal co-bearing sulfide mineral, with CO contained in about one-fifth of the pyrite grains. Up to 30 pct of the CO was concentrated in a bulk sulfide flotation concentrate. [Description provided by NIOSH]
