How to Improve Cyclone Separation
A cone-shaped discharge of 20°–30° reduced angle usually produces optimum conditions for separation. Cyclone control is best obtained by optimising the feed density. With consistent ore types the cyclone feed density is a good indicator of cyclone overflow sizing. A ropy cyclone underflow indicates a very high-density state with a risk …

Understanding the discrepancy between prediction and plant GRG recovery
Fig. 6 shows GRG content in the cyclone overflow as a function of gold particle size for the two cyclone overflow samples. In campaign 1, the overall GRG recovery was up to 30%. For campaign 2, the overall GRG recovery was 27%. Of that gold, coarser fractions (from 212 μm to 75 μm) accounted for 4.25 to 6% of the total …
Hydrocyclone
Hydrocyclones demonstrate a trait that is useful for gold mills—minerals with higher specific gravities have a progressively finer cut-size (whether this is desired or not). In plants with free-milling gold, this leads to gold concentrating in the milling circuits (see Figure 17.13).On a size-by-size basis, concentrations of up to 100 times can occur in cyclone …

Gravity Recovery of Gold From Within Grinding Circuits
Poor partition behaviour of the cyclone combined with upsets in the cyclone feed stream can is the most significant cause of reduced gravity gold recovery. This impact of cyclone inefficiency is illustrated in Figure 5 where a drop of 2% in the efficiency of the cyclone significantly reduces gravity gold recovery.
