目前各选矿厂虽然已經建立了許多原始記录;如处理矿量、矿漿濃度等等,与此同时各选厂多数建立了試驗研究机構,积累了相当数量的研究資料,基本上开展了試驗研究工作。但利用各項原始記录及各項研究資料来鑑别生产成績的好坏却做得很不够。例如我矿生产指标經常波动很大而得不到說明,許多小型試驗和工业試驗由于条件或原料性质掌握的不足而走湾路或中止甚致失败。都說明了在开展这些工作中,
At present, although the various ore processing plants have established many original records; such as handling the amount of ore, pulp concentration, etc. At the same time, most of the selected factories established experimental research institutions, accumulated a considerable amount of research data, and basically carried out experiments research work. However, the use of various original records and various research materials to identify the performance of the good or bad is not enough. For example, the indicators of mine production often fluctuate without explanation. Many small and industrial experiments fail to meet or stop because of inadequate conditions or the nature of raw materials. All illustrate that in carrying out these tasks,
