The first two types may be called single-stage operation, while the last two are two-stage operations. Most AG/SAG mills operate in open circuit (Figure 9.3) when the product size is usually coarse.Usually, provision exists for installing a classifier such as a straight screen, a trommel or a curved DSM screen to remove critical sized pebbles (scats).

The compressive strength of the mineral was 20 MN/m 2. The crusher was next used to crush a second mineral of compressive strength 55 MN/m 2 at 5 kg/s. The feed size of the second mineral was –55 + 40 mm and yielded a product whose average size was 0.4 mm. Estimate the change in power required during the second operation.

Wherever possible model structure is related to the underlying physical processes that govern the behaviour of particulate material in the processing equipment. Predictive models are emphasised throughout so that, when combined, they can be used to simulate the operation of complex mineral processing flowsheets.

In closed circuit, the product from the stage of size reduction is separated into relatively fine and coarse fractions. The coarser fraction is then collected and re-crushed in the same unit as seen in Figure 3.2.In doing so, the load on the equipment for size reduction is increased and a circulating load is established, but the total number of units …

In mineral processing operations, classification and separation of mixtures of fine and coarse particles and also of lighter and heavier particles may be performed in a wet or dry state. The majority of separations are carried out in a liquid environment because of an increased efficiency.

The Euler–Lagrange (CFD–DEM) model, first proposed by Tsuji et al. (1993), solves (1) the fluid flow using the Navier–Stokes equation, (2) the motion of particles using Newton's second law of motion, and (3) the solid–fluid interaction using Newton's third law.The model could capture particle physics better and could predict the transient …

Mineral processing operations present many challenges to process control due to variations in unmeasured ore properties, material transport delays, and nonlinear response characteristics. The conventional control approach relies mainly on the proportional-integral-derivative controllers or rule-based strategy for process control, …

Mineral processing operations generally follow a set of specific steps to separate ores into products rich in valuable minerals (concentrate) and waste streams. The breakdown of the mineral processing steps within the mining chain is illustrated in Fig. 3. Run of mine ore undergoes an initial process of crushing, milling and classification to ...
