Xenia Schulze Bernd, Head of Innolab: "Ultrafine grinding and separation is an enabler for clinker factor reduction and efficient production of special products.Expecting a market demand for big volumes of high fineness products, we have developed a polysius® ultrafine grinding plant to complement our grey2green portfolio.
Ultrafine grinding (UFG) was proposed as a pretreatment method prior to cyanide leaching of old plant tailings of a refractory silver ore. Direct cyanidation of the as-received tailings (d 80: 100 µm) led to a low silver extraction of only ≤43% over 24 h. A size-based diagnostic study has demonstrated that the refractoriness of the tailings ...

Ultrafine grinding process is accompanied by high energy consumption and severe abrasion of devices. In addition, when particles are excessively small, they will become coarser rather than finer through agglomeration if we continue to grind, resulting in "negative grinding." During the ultrafine grinding process, changes will take place in ...
