摘　　要：通过对刚果(金)某低品位氧化铜矿柱浸试验的研究,探讨了提高金属回收率的关键因素。研究发现,适宜的矿石粒度和喷淋强度对于柱浸工艺的有效性至关重要。在柱高、喷淋时间等条件相同的情况下,矿石粒度达到-30 mm,喷淋强度为10 L/m^(2)·h时,可获得较高的铜、氧化铜和钴浸出率,为低品位氧化铜矿的高效利用提供了科学依据。In this paper,the key factors to improve the metal recovery rate were discussed through the leaching test of a low-grade copper oxide pillar in the Democratic Republic of the Congo.It is found that suitable ore size and spray intensity are crucial to the effectiveness of column leaching process.Under the same conditions such as column height and spray time,higher leaching rates of copper,copper oxide and cobalt can be obtained when the ore size reaches-30 mm and the spray intensity is 10 L/m^(2)•h,which provides a scientific basis for the efficient utilization of low-grade copper oxide.

关 键 词：低品位氧化铜矿 柱浸工艺 金属回收率 矿石粒度 喷淋强度
