Grinding Circuit Primary

Spiral separators can therefore be used to take out the coarser iron oxide grains in the primary grinding circuit to save grinding energy and help achieve a higher iron recovery. Figure 9.14 presents a typical flow sheet for processing an oxidized ore containing about 30% Fe using a combination of spiral and SLon magnetite separators and reverse flotation.

For primary grinding circuits, slurring operations are complicated and consist of a limiting factor for the application of a reverse circuit. Therefore, it is necessary to evaluate whether eventual process gains would be annulled by the difficulties imposed by the proposed solution regarding the operation of the circuit.

Grinding systems are either 'open circuit' or 'closed circuit.' In an open circuit system, the feed rate of incoming clinker is adjusted to achieve the desired fineness of the product. In a closed circuit system, coarse particles are separated from the finer product and returned for further grinding.
