摘要：

The effect of pH on the rate of formation of fines for quartz has been investigated. The initial rate of formation of fines is faster when the grinding is performed in an almost neutral (pH 6.8) rather than weakly acidic or basic medium. The results are discussed on the basis of the effect of pH on the fracture strength of quartz and the state of flocculation in the ball mill. The initial rate of production of fines in a ball mill is shown to be a zero-order rate phenomenon in the pH range investigated—i.e., the amount of fine particles produced is directly proportional to the time of grinding. © 1968, American Chemical Society.
