the overflow is now called the flotation concentrate of the circuit. the mineral has been separated from the ore, there for it is in a concentrated form from the original. the underflow is the pulp. when the pulp has had all the mineral extracted from it that the circuit was able to, and is discharged it is then called the flotation tailings of the circuit.
Circuit configurations can be compared by producing the grade/recovery curves generated when each circuit treats the same feed, with the same reagents, but under a range of different operating conditions. the fleet dataset the fleet dataset defines the feed material entering a flotation circuit in terms of feed rate (tph), feed grind (p 80.
Conventional flotation circuit is poorest at only 30%. this poor recovery of composite particles with low surface exposure presented a significant opportunity for the application of hydrofloat technology in a scavenging capacity. the cadia coarse ore flotation circuit is a novel application of aerated teeter-bed technology in sulphide.
the flotation circuit can be optimized independently by measuring, modelling and simulating, but best improvements are realized when comminution and drill and blast are added to create a holistic approach. adding solutions that track ore types and monitor flotation parameters can help to maximize recovery and ultimately, revenue. 2. assembling .
Flotation cells are connected in a network and the tailings stream from one cell is likely to be fed to another cell. similarly, the concentrate flows will generally be fed into banks higher up in the circuit. this results in strong interactions between levels in a flotation circuit. thus if a change in control action is made at any point in .

Flotation circuit real-time density measurement can help to verify changes in the slurry from the grinding circuit to the flotation cells. the effect of flotation feed density on metallurgical performance has been investigated.
Flotation circuit was set-up to recover the zinc. laboratory test work results realized cu-zn recovery differential from a cu/zn separation circuit of over 40-45%. this performance has been achieved in the plant, at 72% cu overall recovery. with the gradual improvements on-going with zinc circuit capacity and.
Flotation is a complex process that is affected by a multitude of factors. these factors may be inherent in the circuit design, or in how the flotation plant is operated. the floatstar suite of control modules utilises advanced process control to overcome design-related limitations and maximise circuit performance during operation.
