##tihuan2##1. Introduction1.1. 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 …

##tihuan2##Equipment Head: In most plants the most common equipment on the pump line is a cyclone. The process design will dictate the required pressure drop across the device, to achieve it's process duty. This pressure is usually quoted in kPa, and must be converted to metres of slurry head, using the following formula: Hequip. = kPa / 9.81x SM metres
