浸出溶液在给人浸出作业之前,以1～10秒/米的流速,流经长度≥20毫米、磁场强度为0.25～0.3特斯拉的磁场区域进行处理。本方法还适宜于堆积场废石或溶液的再处理以及地下矿床的浸出。于是,稀释的硫酸溶液以每秒钟8米的流速,流经长100毫米、磁场强度为0.3特斯拉的磁场处理。在后续的浸出过程中,金属产率增加5％,浸出时间缩短5％。 The leach solution is processed at a flow rate of 1 to 10 seconds / meter through a magnetic field region of length ≥ 20 mm and a magnetic field strength of 0.25 to 0.3 Tesla prior to the leaching operation. The method is also suitable for the reprocessing of waste rock or solution in landfills and the leaching of underground deposits. Thus, the dilute sulfuric acid solution was treated at a flow rate of 8 meters per second through a magnetic field of 100 millimeters length and a field strength of 0.3 Tesla. In the subsequent leaching process, the metal yield increased 5%, leaching time shortened 5%.
