随着直接从矿石中溶浸金属的各种地质技术方案的推广应用,日益迫切需要解决以下经济合理性的论证课题:与传统方法比较采用这些方案的合理性;从平衡表外矿石中溶浸金属的合理性;先开采平衡表内矿石随后溶浸平衡表外矿石的合理性;溶浸标准(溶浸强度和时间、溶浸液浓度、矿石中原有金属含量和残留金属量)的合理性。
With the popularization and application of various geotechnical schemes for directly leaching metals from ores, there is an urgent and urgent need to address the following rationale for economic rationality: the rationale for using these schemes compared to traditional methods; leaching from off-balance-sheet ores The rationality of the metal; the rationality of the first mining of the ore in the balance sheet followed by leaching of the ore outside the balance sheet; the rationality of the leaching standard (leaching strength and time, concentration of the leaching solution, original metal content in the ore and residual metal content) .
