【摘要】 根据原地爆破浸出工艺特点及浸出的物理———化学原理 ,总结提出了影响原地爆破浸出率的主要因素。从矿石的物理、化学性质 ,待浸矿堆的物理特性以及浸出工艺参数 3个方面分析讨论了矿石的裂隙发育程度、矿石中有害元素或化合物的含量、筑堆矿石块度、矿堆的孔隙度、矿堆的渗透性、浸出剂浓度和氧化剂等对浸出率的影响更多还原

【Abstract】 Based on the characteristics of stope leaching and the physical and chemical principles of leaching, the main factors influencing the leaching rate of stope leaching are summarized. The effect of the crack growth degree, the content of harmful elements or compounds in ore, the ore fragment size, the porosity and permeability of ore heap, the lixivant concentration and the oxidant on the leaching rate are discussed and analyszed from the physical and chemical properties of ore, the physical characteristics of the ore heap to be leached and the technological parameters of leaching.更多还原
