Abstract
Spectrographic analysis was used by the Geological Survey to investigate the kind and degree of contamination resulting from the pulverizing in heavy grinding machinery of three different groups of rock samples s (l) six hard rocks, (2) six unconsoliSated sediment s 5 and (3) one massive quartz and one quartzite. It was found that iron can be increase)! as much as 1.5 percent, nickel 0.006 percent, molybdenum 0,002 percent, chromium 0.001 percent, cobalt 0.002 percent, vanadium OoOOl percent, copper 0»003 percent, and manganese 0.1 percent. The data presented a&so show there is danger of contamination of samples from grinding on a bucking board 0
