separation of a complex ore into two or more mineral components and gangue by flotation. mcgraw-hill dictionary of scientific & technical terms, 6e, copyright
abstract-a new method for the treatment of ni-cu sulphides ores from the sudbury region by differential flotation ispresented. the method
this invention relates generally to flotation processes for concentration of ores; without specific restriction to any particular method of producing the flotation of
flotation scheme adopted for concentration of the lead-zinc ore sample consisted of differential flotation separation by depression of zinc bearing minerals using
by differential flotation. a variation of this latter method was tested on prieska ore in the labora- tories of the national institute for metallurgy and in the pilot plant.
various aspects of the galena and sphalerite concentration process in a differential beneficiation plant are discussed. attention is focussed mainly on the

us. patent no. 2,492,936. such reagent and process have been and are being extensively employed in the milling of copper sul-. fide ores and concentrates
sulfide flotation followed by differential flotation was attempted. in this process, rougher-cleaner concen- trates recovered with a starvation amount of a copper-.
screens per se are not covered by this subclass but are classified in b07b, even if they are being used in a wet process. all other apparatus for the separation of
of unrecognized factors in the process brings about failures lln differential flotation of mixed lead-zinc sulfids with alkaline carbonate solutions, it has been found
however, a hf-free flotation process using a mixture of the cationic and anionic collectors for the separation of feldspar from sand was described by katayanagi [4]
differential flotation of sulfide ores for recovering refractory gold. abstract. a process for recovery of gold from gold-containing raw materials
flotation. (also known as froth flotation) a separation process whereby water and chemicals are added to a mixture of solids to form a pulp while developing
hence, where one is interested in the total microfossil population, rather than in just the spores and pollen grains, this procedure is unsatisfactory. an alternative
bulk flotation sequence: under the bulk flotation process, a bulk cu-co flotation concentrate is produced at natural ph with xanthate,
materials and procedure. bulk sulfide flotation concentrates were prepared by grinding a 1200-gram sample at 50 solids in a stainless steel rod
process., 2: 207--218. the suitability of a new reagent, kr6d, as a depressant for galena and sphalerite in a differential sulphide flotation stage has been tested.
froth flotation is a crucial and complex process, which has been used in his expertise on differential equations and always motivating me to reach higher level.
this invention relates to the froth flotation process for the recovery of minerals and has to do particularly with the separation of lead and/or copper sulfides that
