particles in solution, outotec e500 flotation cell status different types of flotation cellswith economic metallurgy as its objective, flotation machines have changed over the s as the demands on the process have changed. see full list on 911metallurgist one of the significant changes made to reduce operating costs has been the extensive use of pressure med rubber parts to withstand abrasion and thus reduce maintenance. design of flotation cells has been improved and simplified to handle increased tonnage. one such development was the freeflow tank design. another change has been the use of flotation mechanisms which can be removed from the flotation machine quickly for the inspection or change of wearing parts. a simple change in the method of premixing air with pulp as it enters the throat of the flotation impeller has made it possible to reduce power cost as much as 50%. development of larger flotation cells means fewer flotation cells are needed to do the job. this simplifies maintenance and reduces construction costs. see full list on 911metallurgist to meet the varying conditions and requirements, two basic types of flotation machines have been developed: (1) celltocell
