Usually, the beneficiation process is simple. Firstly, ore is ground until the material whose size is around 200mesh takes up 50%~ 70%. Next, the material would undergo coarse separation once, careful separation twice or three times and scavenging once or twice. If the copper ore is fine, phased grinding and separation process is adopted. For processing bornite, the rough concentrate would be ground again and sent to be separated carefully. Through coarse grinding, coarse separation and scavenging, coarse rough concentrate can be got which would be ground once again and separated carefully to produce high-grade copper concentrate and sulfur concentrate.
