东风山金矿由于选矿工艺流程设计不合理，致使选矿生产能力低，技术指标不稳定等。针对生产中存在的技术问题，结合矿山实际采取了有效技术措施，对工艺流程进行了改造，使矿山年增经济效益２４０－９万元。
Due to the unreasonable process design of the beneficiation process, the Dongfengshan Gold Mine results in low ore dressing capacity and instable technical indicators. In view of the technical problems existing in the production, effective technical measures have been taken in connection with the mines and the technological process has been reformed so that the mines will have an annual economic benefit of RMB240 ~ 900,000.
