This flowsheet is the lowest in price and can be used on what are commonly termed as free milling gold ores where a high percentage of the values are free and where these values are unlocked at reasonably coarse grinding. This flowsheet is often used for treating high grade pockets. The ball mill is in open circuit and the sie of the product to amalgamation plates is controlled by a

for southeastern Alaska open pit mining is most common. During milling ore is usually crushed and ground in a ball mill subsequently gravity concentration is used to remove the largest gold particles. Remaining ore is reground classified and thickened recycled through the gravity concentrator and then processed in cyanide vats for 48 hours
Copper is typically extracted from oxide and sulfide ores that contain between and percent copper. The refining techniques employed by copper producers depend on the ore type as well as other economic and environmental factors. Currently about 80 percent of global copper production is extracted from sulfide sources
The mill began processing ore in December 1987. The KCJV concentrated their efforts on the 1500 1700 and 2200foot levels of the mine in the search for rich ore shoots. Additionally the venture experimented with mining old pillars. One test run of visibly barren pillar material yielded 200 ounces of gold when processed in the mill

Following removal of the native copper from the ore through the gravity circuit or when nonnative copper ore bypasses this circuit the ore continues to the gravity thickener and the thickened ore then feeds through to the ball mill. Milling of ore to a sie that is suitable for flotation is carried out in a conventional ball mill
