Gold flotation. Flotation process is widely used for lode gold processing. In most cases, the flotation method has a good effect in sulfide-containing gold ore with high floatability. In addition, the flotation process is also used for polymetallic gold-bearing ores such as gold-copper, gold-lead, gold-copper-lead-zinc-sulfur ore.

1. Crushing System. The chute feeder feeds raw material to the primary jaw crusher stably and evenly and can feed 0-300mm stones. If bigger in size and capacity, you can use a grizzly vibration feeder. The primary jaw crusher crushes the big rock to a smaller size, about 0-80mm. The output sends a fine jaw crusher to crush again to below 25mm ...
