DetailsCombining the benefits of circular cells with the unique features of the patented DV™mechanism, the RCS™ (Reactor Cell System) flotation technology has been developed to create ideal conditions to maximize flotation performance for all roughing, cleaning and scavenging duties. The cell can be modified to handle high density slurries.
DetailsComplete RCS flotation plant was commissioned with advanced automation and process controls. Result Flotation cells are designed to handle fluctuations in capacity.
DetailsThe operation of the process is affected by the mineralogical character of the ore, the grade of feed, the kind and quantity of flotation agent and, to a less extent, by the temperature of the pulp, the place and method of adding the flotation agent, the type of flotation machine used, and the method of removing concentrate.
DetailsFlotation is both a science and an art. It brings together many complex variables. Such basic factors as knowledge of mineral structure, chemical reagents, pH of mill water, pulp density, temperature, technical skills of the operator, the dependability of the flotation machine, as well as a host of other factors which affect the flotation of ...

DetailsUnfortunately, the conventional flotation cell achieves high recovery only in limited size ranges. For example, a sulfide ore might float very well at 90 to 120 microns, but not at 50 or 150 microns.
DetailsColumn flotation cells, like mechanical cells, are used to perform mineral separations. Column cells do not use mechanical agitation (impellers). Instead, mixing is achieved by the turbulence provided by the rising bubbles. ... Gold Flotation & Columns. In another unique application, hot (120°F) flotation of hot leach tails definitely favored ...
DetailsThe Air Flow Number should lie within a narrow range for optimum flotation results for any one cell. Harris gives values for most commercial cells while Table 4 has more detailed data for Denver and Wemco cells based on more recent measurements for sizes up to over 30m (1,000 cu. ft.).
