摘要
氰化浸出是黄金生产中的代表性工艺,其中解吸电解环节至关重要,直接关系到黄金产量。内蒙古太平矿业有限公司采用破碎—堆浸—活性炭吸附—解吸电解—冶炼的选矿工艺,在生产中,解吸电解设备常因粉炭过多导致堵塞,影响生产效率和黄金产量。探讨了内蒙古太平矿业有限公司在黄金生产过程中解吸电解设备的应用及其面临的挑战。通过深入分析温度、压力、氢氧化钠用量等工艺参数对解吸电解效果的影响,结合设备运行中出现的实际问题,提出了一系列针对性的优化措施,包括调整解吸液用量、降低循环流量、扩大炭棒网开孔面积、增加过滤器过滤面积和目数等,有效解决了设备堵塞、生产效率受限等问题。研究结果可为同类型设备的优化提供借鉴。
The cyanide leaching is a representative method in gold production,with the desorption electrolysis stage being crucial as it directly affects gold output.Inner Mongolia Pacific Mining Co.,Ltd.employs a beneficiation process of crushing-heap leaching-activated carbon adsorption-desorption electrolysis-smelting.However,during pro⁃duction,excessive carbon powder frequently clogs the desorption electrolysis equipment,reducing production efficiency and gold yield.This study examines the application of desorption electrolysis equipment in the gold production process and its associated challenges.By analyzing the effects of process parameters such as temperature,pressure,and sodium hydroxide concentration on desorption electrolysis performance,and addressing issues observed during equipment operation,a series of targeted optimization measures were proposed.These include adjusting desorption solution dosage,reducing circulation flow,enlarging the carbon rod mesh openings,and increasing the filtration area and meshes of filters.These measures effectively solved clogging and efficiency limitations,providing valuable insights for optimizing similar equipment.
