Free Milling Gold Gold ore is considered free milling when over 90% of the gold can be recovered by a conventional gravity cyanidation process with low reagent consumptions at a grind size of 80% passing 75 µm Some examples of free milling gold ores include quartz veined deposits and oxidized ores
ore treated was very difficult to mill In the first two days the mill experienced numerous power dips overloads and on at least seven occasions the feed to the mill had to be completely stopped to grind the mill out Also the mill load varied in the range of 125 to 165 tons These disturbances propagated throughout the milling circuit and
The mill was originally designed with a capacity to process million tonnes of ore per year but the actual mill throughput in 2022 was approximately million tonnes per year The ore to be milled is managed through a number of stockpiles that receive ore of different metallurgical character and of different grade ranges and thus allow blending of the mill feed
