  • Ball Mill: Is the Grinding Fineness the Finer, the Better ...

    In actual production, some concentration plants think that the finer the grinding fineness, the easier it is to improve dressing efficiency. However, this cognition has led to a lot of winding courses in the processing plant, which not only greatly reduces mineral recovery rate, but also increase investment and operating expenses of the concentrator in vain.

  • Fine Grinding as Enabling Technology – The IsaMill

    When fine grinding pyritic concentrates of precious metals, it is common to follow the fine grinding stage with a pre-aeration stage to remove active pyrite and pyrrhotite before cyanidation. Worn steel media in the ground pyrite can significantly increase the pre-aeration time needed. In a recent application of the Isamill, the existing regrind mill before gold leaching was consuming 10 t/day ...

  • HIGMILL FINE GRINDING TECHNOLOGY OPTIMISES RECOVERY

    A seasoned charge reduces the voidage and maximises the surface area of the charge, this being beneficial to fine grinding. Based on the signature plot monitoring, it was estimated that it took 2 to 4 weeks of operation to season the charge. The amount of clay and ultrafine particles present in the feed greatly influences the viscosity.
