GRINDING CIRCUIT DESIGN FOR ADANAC MOLY CORP USING A GEOMETALLURGICAL APPROACH. DAVID BULLED –– SGS MINERALS. ABSTRACT. This paper describes the design of an SABC grinding circuit using CEET technology applied to grindability data produced from testing 100 samples and distributed across the blocks of a mine plan using a geostatistical approach.
Four circuit configurations were compared by means of simulation, namely; 1. SABC, Semi-autogenous milling from gyratory crusher prepared (minus 200mm) feedstock followed by reverse fed closed-circuit ball milling -10.36mØ x 5.26m and 6.73mØi x 9.45m § 2. Conventional three stage crushing followed by two-stage ball milling- 6.24mØi x 9.6m
The designed ball milling circuit product is 80% passing 150 µm. Several large tonnage copper porphyry plants in Chile use an open-circuit SAG configuration where the pebble crusher product is directed to the ball mills (SABC-B circuit).

circuit is shown in Figure1. It is commonly referred to as a SABC circuit, for Semi-Autogenous Ball mill Crusher (SABC). This circuit shows a semi-autogenous grinding (SAG)/ball mill circuit where both grinding mills are in closed circuit, with the SAG mill closed with a crusher to control the amount of 'critical size' material in the circuit.

the specific energy of the crushing section, the HPGR section and the tumbling mill section separately. Hence, for example, in the case of an SABC circuit the total specific energy of the entire comminution circuit will be predicted plus the individual specific energies of the primary crusher, pebble crusher and combined SAG/Ball mill stages.

• Investigates the feasibility of a novel AG-Crusher-HPGR circuit using rock samples from a large copper-gold mining project. The approach was to develop and evaluate the circuit design for high-tonnage operations with mixed hardness ores containing clay.
In the case of SAB/SABC circuits the transfer size is the product of the SAG mill circuit and the feed of the ball mill circuit. Hence if power-based equations such as eq. 1 and eq. 2 are
COMMINUTION SERVICES GRINDING CIRCUIT DESIGN, OPTIMIZATION AND PRODUCTION FORECASTING INTRODUCTION In most processing plants, the grinding circuit represents the largest capital investment. With the emergence of low grade – high tonnage operations, this is especially true now that economics dictate the use of the largest milling
