Currently,the gold ore processing methods are as follows: First of all, send the large gold ore to jaw crusher evenly and continuously for primary crushing by vibrating feeder. And then, transport the crushed gold ore to cone crusher for secondary crushing. Then, we need to use a vibrating screen to separate the gold ore into different sizes.
