摘　　要：研制的自清扫筛面吸附设备成功解决了树脂矿浆（RIP）体系吸附设备树脂分布不均以及树脂与矿浆级间分离困难两大技术难题。工业生产实践证明，工业型设备运行可靠，具有良好的水力学和动力学性能，自清扫分离筛在不加任何外力下，w（固）为40％的矿浆通过能力可达50～80m^3（m^2·h），吸附尾液中金质量浓度小于0．02mg／L，吸附率大于99．52％。Adsorption equipment with auto-cleaning screen for extraction of gold in resin-in-pulp（RIP） system was developed. The experimental results on the adsorption equipment and the result of its industrial production application in a gold plant are described. Two key technical difficult problems in mechanical stirring equipment for RIP system,that is, the uniform resin distribution and the RIP interstage effective separation, have been solved. The industrial application proves that the equipment has good hydrodynamic and kinetic characteristics, the flow rate of pulp through the interstage separating screen achieved to 50-80 m^3/（m2 · h） without any force from outside system, the content of gold in the adsorption tail solution was less than 0.02 mg/L, and the adsorption efficiency was greater than 99.52%.
