Increased fine particle recovery Specifically designed to maximise fine particle recovery, the Dorr-Oliver flotation cell is the most energy efficient, technically advanced, forced-air flotation machine on the market. Its air dispersion capabilities exceed all competitive forced air designs – an important consideration for fine particle recovery.
view moreEfficient particle recovery with self-aspirating flotation The self-aspirating WEMCO flotation technology, whether incorporated into the original 1+1 flotation machine design or the newer-generation SmartCell ® flotation cell, combines ease of operation with improved metallurgical performance. The result is excellent particle recovery in a simple, proven …

view more· Sizing starts by estimating cell volume. The calculation uses target slurry feed rate with an estimate of flotation time to achieve target recovery, for example, based on lab testing with a scaling factor. This gives the required total cell volume (N·V cell ), that is, the number of cells (N) times the cell volume (V cell ).

view more· This paper presents a characterization of the different minerals recovered along industrial flotation circuits. Plant sampling campaigns, performed in a copper industrial concentrator in Chile, provided the data for the study. Two rougher flotation banks consisting of cells of 130 m 3 and 300 m 3, were evaluated.
