Ultrafine Grinding an overview ScienceDirect Topics

According to Hourn et al (2005), ultrafine grinding of sulfide minerals to particle size of 80% passing 8–12 μm will eliminate mineral passivation by sulfur precipitates, as the leached mineral will disintegrate prior to the precipitate layer becoming thick enough to passivate it The oxygen used for oxidation is injected into the base of the Albion leach reactor at supersonic velocity to achieve the required mass transfer and Ultrafine Ultrafine Grinding Mineral Enrichment Ultrafine grinding is used to liberate gold finely disseminated in metallic sulfides KCGM is the first gold mine using ultrafine grinding followed by cyanidation Ellis and Gao 2002 The gold sulfide concentrate is grind with an IsaMill to a P 80 of 10–12 μm Mineral Barite Grinding Millmill for grinding barite with enrichment Small stirred mills that have been used in the paint and other chemical industries for ultrafine grinding are now becoming more widespread in the minerals industry The definition of ultrafine grinding is broad and vague, referring to nanosized grinding in some specialised industries but in this book, ultrafine grinding for the mineral industry will refer to sizes less than 20 μmStirred Mills – Ultrafine Grinding ScienceDirect
