Research object and aim. Flotation schemes development and optimization is a significant trend in flotation technology improvement. The prospect of developing flotation schemes is connected with the use of open circuits which realize the conditions approaching the ideal flotation cascade. This research aims to study the possibilities of improving the effectiveness of open flotation circuits based on rational integration and flotation at certain stages of products under fractional feed of a collecting agent in the front of flotation.
Methodology. In order to obtain the regularities of forming the products of different qualities under fractional feed of a collecting agent, chamber assaying of open circuits have been carried out at two processing plants with copper ore processing. In laboratory conditions, copper ore flotation kinetics has been studied under fractional feed of a collecting agent into the process. Chamber assaying of open circuits and copper ore flotation kinetics study under fractional feed of a collecting agent into the process determined step-like formation of froth product in the front of flotation. The obtained regularities can be applied when forming open flotation circuits through reducing the blending of the products of different quality which leads to significant increase in flotation indicators.
Summary. Revealed regularities open up additional possibilities to improve flotation of sulphide ore dressing based on the use of open flotation circuits with fractional feed of a collecting agent in the front of flotation.
Key words: open flotation circuits; fractional feed of a collecting agent; flows formation; flow chart; layout solution.
