An evaluation of the modal analyses performed around this copper flotation circuits revealed the following: During the plant survey the copper rougher circuit recovered about 60% of the copper, 20% of the lead and 5% of the zinc into the rougher concentrate. Most of the remaining copper and lead was recovered into the scavenger concentrate.

The electrolytic flotation has mainly been used for small plants with capacity between 20 and 30 m 3 h −1. In dissolved air flotation, the bubbles are produced by controlling the pressure of water saturated with air. Three main processes of dissolved air flotation include vacuum flotation, microflotation, and pressurized flotation.

SUMMARY. The flotation plant flowsheet simulation models provide an efficient way to assess existing circuit operation, further optimize its operating conditions and to evaluate different circuit reconfigurations. When planning a new flotation plant design, simulation models can be used to design the circuit configuration and cell sizing.

A flotation plant is a site where the final stages of gold mining takes place. More precisely, it's where the valuable minerals that get extracted from the mine are separated from all the other things that get dug out, such as waste materials and other bi-products. The flotation process requires vast areas of land as well as huge amounts of ...
