    Nov 01, 2003  In February 2001, Kalgoorlie Consolidated Gold Mines (KCGM) commissioned its first full-scale ultrafine grinding (UFG) plant to supplement its existing roaster-concentrate treatment capacity. The process involves the fine grinding of refractory pyritic concentrate to 10 μm followed by direct cyanide leaching for gold recovery. By this means, gold can be economically extracted from the ...

    May 01, 1977  When machining an electrically nonconducting material with a diamond wheel the machining temperature can be measured by means of “two imbedded contiguous electrodes” (the 2ICE method) which give temperature readings from small volumes in the contacting layers of the tool and the machined material. The time constant of the method is negligibly small and the readings stable, and
