联系到加工复杂的和难浸矿石或精矿,以及与环境保护诸因素有关的一些问题,促使人们采用提高温度和加压的办法来强化湿法冶金过程。加压浸出能在装有搅拌机的立式、卧式或球形高压釜中进行。如处理大量物料时,可用一个到几个常规单体设备。而采用技术简单的 VAW 管式浸出器,在加压和高温的条件下,具有相当高的生产能力并能充分利用热能。本文叙述了管式浸出器优于高压釜之处,介绍了管式浸出器实验室研究的结果,以及应用于各种冶金过程的情况。
Linked to the processing of complex and difficult-to-leach ores or concentrates, as well as some issues related to environmental protection, prompting one to intensify the hydrometallurgical processes with increased temperature and pressure. Pressurized leaching can be carried out in a vertical, horizontal or spherical autoclave equipped with a stirrer. When dealing with a large number of materials, available from one to several conventional monomer equipment. The use of simple VAW tube extractor, under pressure and high temperature conditions, has a very high production capacity and can take full advantage of heat. This article describes the superiority of the tube extractor to the autoclave. The results of the laboratory study of the tube extractor and the application to various metallurgical processes are described.
