The very old problem of processing by flotation, the fine ("F" 15-5 µm) and ultrafines ("UF", < 5 µm) mineral particles continues to be one of the major technical challenges in the area of ...
Mechanical flotation cells utilise an impellor to agitate the slurry and produce turbulent regions for bubble particle attachment, whereas in pneumatic flotation cells pulp and air are introduced together into the cell through a nozzle, also termed a downcomer, that promotes bubble-particle contact (Gupta and Yan, 2016).
grades and the demand for improved flotation selectivity, all bring new challenges to minerals processing flowsheets. The Outotec Concorde Cell technology helps flotation circuits overcome these challenges and achieve improved efficiency in fine and ultra-fine particle recovery. Concorde Cell™ is an ideal flotation solution due to:
Until only a few years ago mechanical flotation machine capacity was limited to eight to 15 tons of ore per running foot per 24 hours, and this meant that a "small" 10,000 TPD mill needed in the neighborhood of 150 rougher cells, while a 30,000-ton mill would need about 500 rougher cells. With the same units the mill of tomorrow would …
