一、导言矿业工程包括物理选矿和化学选矿,或低品矿床的提纯。为了生产工业用途的产品,例如金属、水泥、肥料等,对提纯的矿物进一步加工,需要学科之间的合作。A.M.Gaudin将矿物精选定义为不会破坏矿物物理和化学本性的处理。但是那位著名教师的一位毕业生,即本文作者并不完全赞同他的观点,即使明显的矿物处理的物 I. Introduction Mining engineering includes physical beneficiation and chemical beneficiation, or purification of low grade deposits. In order to produce products for industrial use, such as metals, cement, fertilizers, etc., further processing of the purified minerals requires interdisciplinary cooperation. A.M. Gaudin defines mineral processing as treatment that does not destroy the physical and chemical properties of minerals. But one of the famous teacher’s graduates, the author of this article, did not quite agree with him, even though the obvious mineral-treated thing
