    Gelatinization occurs by mechanical means such as grinding pressure and by hot water. Soft feed at an environmental temperature of 25°C can be brought to a temperature of 85°C by the addition of 4 to 6 percent moisture from steam. Frictional heat due to passage of feed through the pellet mill adds 2 or 3 degrees of temperature.

    Abstract. In some mining operations one of the most important roles played by the geologist is the supervision of grade control. In an open-pit operation this involves the sampling of blast-hole cuttings produced by down-the-hole hammer drills and the classification of bench reserves into ore low grade or waste material or into various metallurgical types.
