Ultrafine Grinding an overview ScienceDirect Topics

G. Deschênes, in Gold Ore Processing (Second Edition), 2016. 4.4 Ultrafine Pyrrhotite Concentrate. 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.

ultrafine grinding of pyrite

Coarser grinding sizes with 3.36 mm and 0.595 mm showed less than 30% of gold extraction as expected. However, the gold extraction with 75 µm only increased to 38% and up to 43% with ultrafine grinding at 3 µm. Based on the observed results, it was determined that ultrafine grinding was not an applicable option for the refractory ores.

Ultrafine Grinding an overview ScienceDirect Topics

Ultrafine grinding or nanosizing terms were frequently used for the process, when the size of the particle lies in the range of nanometers compared to the other synthesis method. Mechanical attrition methods lead to higher production rates (tons of nanomaterials can be produced in an hour) and widely used in industrial production like metal, clay, and coal powders [22–28] .
