目前,对普遍存在的两种倾向,应值得注意: 一当考虑包括矿石金属含量与回收率等某些工艺指标的主从关系时,对运用统计分析方法,采取了形式主义的态度,并以此类似数据做为处理贫矿石的依据; 二选矿厂的评价工作是将精矿金属回收率与中等水平的个别选厂指标相比,而该厂所处理的难选矿石其指标一般来说很差,并且是在较困难条件下,由于经济上的促使,而所采用的生产工艺流程是不合理的。
At present, two prevalent tendencies should be noted: the formalistic approach to the use of statistical analysis when considering master-slave relationships that include certain process indicators such as ore metal content and recovery, This similar data is used as the basis for dealing with poor ore; the evaluation of the second concentrator is to compare the recovery rate of concentrate metal with the average level of individual beneficiation indicators, while the indicators of the refractory ore handled by the plant are generally very Poor, and is under difficult conditions, due to economic impetus, and the production process used is unreasonable.
