i have done many bottle roll trials with the same feed of the CIL/CIP tanks but bottle roll trials give lesser recovery than CIL/CIP 's recovery. Anybody had the same situation? any ideas?

Gold loss in carbon fines is a major concern for gold mines. I am looking for percentage of carbon fines generated during regeneration of carbon in rotary kiln. Anyone data available from industry?

Hello Rob I used Ta symbol for stand for tailings. The wolfram in tailing was 0.03%W while average of wolfram from outcrop samples was 0.05% W is the 0.05% W grade from outcrops minable?

Best split 'till the weight of the ore is 150 grams. Better yes is to do your leach test with 1000 grams
