Jan 01 1988018332Wheal Jane Tin Mine South West Cornwall England processes a fine grained cassiterite ore 0 85 Sn by a combination of gravity concentration and flotation The material too fine to be effectively recovered by gravity concentration 70 45 um is deslimed at 4 um and treated by froth flotation to produce a low grade tin concentrate.
Fine grained cassiterite flotation italianglostersocietyit Tin mining and processing methods of the fine grain size of the cassiterite fine tin flotation to produce concentrates acceptable to tin Chat Online Flotation Of Cassiterite With Modified Fatty Acids Fine Grained Cassiterite Flotation If gangue material makes selective flotation of Barite difficult FLOTINOR174 FS 2 fatty acids Chat.
The nominal size range for cassiterite flotation is between 2 and 100 microns The top size is variable depending upon the liberation of the cassiterite particles Cassiterite grains coarser than 100 microns are difficult to float whilst grains finer than 2 microns give selectivity problems Hence the feed for cassiterite flotation should be reduced to 95 minus 100 microns and then deslimed.
In recent years due to the increasing fine grained dissemination of cassiterite with gangue minerals flotation has become a supplementary andor alternative method for comprehensive cassiterite recovery.
The invention relates to a combined mineral dressing method of fine grain and micro grain cassiterite which gives up the single mineral dressing method of fine grain and micro grain cassiterite for years The invention adopts the effective combination of two time flotation operation magnetic separation operation desliming and dewatering operation and reselection operation provides a new.
Tin resources are abundant and complicated in China Most of tin resources come from cassiterite Normally the main beneficiation method of coarse cassiterite ore is gravity separation However as for the fine grained cassiterite flotation and joint processing techniques are generally selected to improve the low recovery from gravity separation.
The invention discloses a composite type copper mine flotation agent The composite type copper mine flotation agent is composed of isobutyl sodium xanthate ammonium dibutyl dithiophosphate sodium dodecyl benzene sulfonate sodium nonyl xanthate and activating agent isobutyl sodium xanthate has strong capturing ability and is the capturing agent applicable to copper lead zinc and nickel.

Particularly useful for processing fine grained ores that are not amenable to conventional gravity concentration Figure 1 The flotation system includes many interrelated components and changes in one area will produce compensating effects in other areas Klimpel 1995.
One process that has been successfully separating fine and ultrafine particles for more than 100 years is flotation which in its essential characteristics was patented in Dresden in.
Flotation Tests of Sulphidized Products Low recoveries of cassiterite are obtained by gravity concentration of lode deposits particularly if the cassiterite calls for fine grinding of the ore And it is precisely this finely ground ore that is the cause of the low recoveries.
