4、 Value of mineral products and benefits of Monti leaching process

摘要

The invention refers to a process for recovering valuable metals from sulfide ores, including ore crushing in a primary chopper (14) of about 40 cm and less than 40 cm, and chopping the ore by one or more of the following pretreatment processes. For example, bulk classification (16) and screening classification (20), followed by thickness fluctuation (46 / 50),Or gravity separation or magnetic separation. 1. Waste streams with particle size greater than 100um produced by Huiyi pretreatment process (54) are piled up into a pile (26) and a large amount of leachate. This comprehensive process adopts the pre beneficiation technology which is most suitable for the characteristics of specific ore body; At the same time, a low-grade flow is created to provide a much higher recovery than the normal bulk leach in low-grade site operations.
