【摘要】 实验研究铜矿在一定喷淋强度下溶浸时水分运移的基本规律。实验表明 ,矿柱的喷淋过程是一个矿物颗粒吸湿 ,颗粒之间的孔隙则是一个逐渐由非饱和转化为饱和的过程。只要适当地控制好喷淋强度 ,就能使矿柱或矿堆保持长时间的非饱和状态 ,有利于有用元素的浸出。对于溶浸而言 ,需要保持矿柱较长时间的非饱和状态。因此 ,喷淋强度选择小的值的比较好 ,从实验结果可以看出 ,对于该实验所选取的矿柱 ,控制喷淋强度在 1.2 43E～ 2cm/min和 5 .2 3 8E～ 2cm/min比较合理更多还原

【Abstract】 The paper studies the basic law of water transport by test when the copper is leaching under some volume of sprinkling. It may be concluded that the sprinkling of ore-column is process which the grain of ore is becoming wet and hole between the grain is becoming saturated. Controlled the proper volume of sprinkling, ore-column can keep unsaturated long, which is benefit to leaching.It is very important to keep unsaturated state for long time in ore-column, so the lower value of volume of sprinkling is choiced. The result shows that volume of sprinkling is proper between 1.243 E～2 cm/min and 5.238 E～2 cm/min for this experiment.更多还原
