摘要
针对我国砂金矿“小而分散,贫而细”的实际特点,本文提出了一种新型便携式选金机组。经试验表明,该设备运行可靠、操作简单、能耗低、投资少、选别效率高,特别适合小规模砂金矿开采使用。
Placer gold in China has the characteristics of small scale, wide distribution, low grade and fine granularity. The authors invented a new type of portable placer gold washing set. Experimental researches reveal that the equipments are feasible, simple, energy saving, economical, efficient and especially suitable for small placer gold mines.
