锡石单体游离率是选矿的不可缺少的原始资料。目前,测定方法满足不了要求,速度慢、精确度差。如对0.037毫米粒级而言,每人每班最多做二个样品,做一个混合粒级样品往往需要几天时间,并难以确定误差范围。因此,有必要寻求速度快、准确度高的测定方法。 Cassiter monomer free rate is an indispensable raw material for dressing. At present, the measurement method can not meet the requirements, slow, poor accuracy. For a 0.037 mm particle size, up to two samples per class per shift, it can take days to make a mixed particle sample and it is difficult to determine the error range. Therefore, it is necessary to seek fast, accurate determination of the method.
