refractory gold ore concentrate was ground down to 74 #181;m using laboratory ball mill and steel balls. The grinding process results in 80% passing particles size of 74 #181;m. The particle size distribution of ground samples was determined using Retsch wet vibratory sieve shaker. These were then split
refractory gold ore is goldcontaining ore that is resistant to recovery by direct cyanidation and carbon adsorption processes. More specifically, it is an ore that has a gold recovery rate of less than 80% when direct cyanidation is applied to it. Dr Chris Fleming, senior metallurgical consultant at
