For this reason, ultrafine grinding is also known as mechanochemical activation, which significantly enhances subsequent mineral processing and impacts positively on hydrometallurgical operations (Ficeriová et al., 2011, 2007). Ultrafine grinding must be carried out using specialised equipment, specifically stirred media mills.
