前言每个选矿工程师都知道,使用正确的公式对於评价选矿过程说来具有多么重大的实际意义,并且这样的公式能使我们发现选矿过程中一切现象的本质,从而使我们正确编制工业性的选矿流程、选择机器以及确定切实可行的技术操作制度。这些资料连同经济方面的核算,就能使我们判定逃矿过程的技术经济效果,最终可以断定企业是否能有赢利。 Foreword Each beneficiation engineer knows how important it is to use the right formula to evaluate the beneficiation process and such a formula allows us to discover the nature of everything in the beneficiation process so that we can properly engineer the industrial Beneficiation process, selection of machinery and determination of a viable technical operation system. These data, together with economic accounting, enable us to determine the technical and economic effects of the escaping process and, ultimately, whether the business can make a profit.
