WhatsApp: +86 180378085111. Background. With the continual depletion of high grade simple ore bodies, more complex, finely disseminated ore bodies are being processed, which has led to an increase in the prevalence of fine grinding (Sinnott et al., 2006).This has been evident in the platinum group element (PGE) industry in South Africa, where the Bushveld Complex hosts 70% of global PGE reserves.
