The crushed copper ore (containing, for example, % Cu and % Mo) is fed to the grinding circuit where water is added and the ore is ground to the proper size. Lime and an oil for collecting molybdenum are usually added in the grinding circuit. A copper collector may also be added at this point. The pulp progresses to the flotation cells.
Operations Processing . The plant is based on conventional carboninpulp technology which is an efficient and low cost operation. It comprises a gyratory crusher, a ball and SAG mill grinding circuit, gravity recovery and cyanide leaching.
Advanced Grinding Circuit Control Using Online Analyzer Systems. Grinding circuit efficiency is pivotal to the performance of ore beneficiation. However, establishing stable operating conditions to maximize throughput, energy efficiency and ensure optimal particle size is a challenging task for any grinding circuit.

CYCLONES 4444 Introduction The purpose of the cyclones in the circuit is to size the mill discharge slurry. Two product streams are generated by the cyclones; • A fine 'overflow' stream which reports to the leach/adsorption tanks. • A coarse 'underflow' stream that is recirculated to the mills for further grinding.
