Further reagents collectors are added to the flotation cells 3 5 and 9 The collector distribution pattern is 32% for ball mill feed 32% for the third rougher flotation cell Flow sheet for Sungun copper flotation plant 20% for the fifth rougher flotation cell and
·A series of flotation cells consists of five tanks connected in cascade with control valves between the tanks and a slowly varying flow of mineral slurry into the first tank This paper deals with
·The performance of froth flotation cells is affected by changes in unit load feed quality flotation reagent dosages and the cell operating parameters of pulp level and aeration rates Slime and insoluble depressant in flotation of copper and other metallic sulphides Add to cleaners Zinc Hydrosulphite A water soluble white powder 10%
·The Flotation Process Until quite recently copper ore had to be hand picked if the extraction of the metal was to be economical In fact in the last century ores of 4 percent grade were regarded as almost valueless The powdered product of grinding the ore is fed into a series of tanks called flotation cells which are filled with a
·Metso s flagship product for flotation the RCS flotation cell is an all purpose flotation machine suitable for applications including roughing cleaning and scavenging RCS cells use Metso s patented Deep Vane DV mechanism to float various minerals and are available in volumes from m 3 to 600 m 3 These are complemented by the
·The selection of the size number and type of flotation cells for a particular duty depends on two important factors These are the required flotation residence time and the physical constraints of how much concentrate can be recovered for a given froth surface area and concentrate lip length The residence time is influenced by ore type and
·A modal examination of the products produced by the copper flotation rougher scavenger circuit reveal important information regarding the limits to the efficiency of the process imposed by mineralogy fragmentation and flotation capacity Let s discusses various aspects of rougher flotation circuit performance and how to evaluate its results
·An Example of flotation cell capacity and circuit retention time approximation Estimate the volume of conditioners and flotation cells required to handle 9100 dry tons of ore per 24 hours at 30% pulp solids by weight with an ore specific gravity of Five minutes conditioning time and 15 minutes flotation time are desired
