RE:RE:RE:RE:RE:RE:RE:RE:RE:RE:The Billion share club - what a joke !Thanks for your extremely basic explanation of what makes a mine economic, my man. By the way they have a primary AG, secondary pebble, and two cone crushers. The limitation isn't the grinding circuit, and even if it were, that's the simplest and least expensive aspect of their flow sheet. They have two leach circuits and are processing refractory aresenopyrite ore with nuisance copper. They're roasting sulphides on site, and you think the grinding circuit is the limitation?
