Question: The grinding circuit of a zinc concentration plant is shown in Figure 2. The plant is treating 250tph of ore containing 4% moisture. The cyclone underflow contains 50% solids by volume, the overflow 30% solids by weight and the ball mill discharge 45% solid by volume. The circulating load ratio of the circuit was found to be 300%.

The complex mineralogy of the Porgera resource has a pronounced effect on process selection for the recovery of refractory gold and silver. Intimate association of gold with pyrite necessitates a high degree of sulphur preoxidation to achieve acceptable levels of gold recovery. Acid pressure oxidation has been demonstrated to be the only …

The ore lumps from the mines have the lump size of 10 - 100 cm while the individual minerals have grain sizes below 0.1 mm. Hence, the first step in any ore dressing plant is to aim at liberation by size reduction or comminution. Comminution of any ore is carried out in several stages using different crushing equipments.

C = F/K = F (f — t) / (c-t) = the weight of the concentrate. Recovery %. Represents the ratio of the weight of metal or mineral value recovered in the concentrate to of the same constituent in the heads or feed to the process, expressed as a percentage. It may be calculated in several different ways, depending on the data available.
