COLLECTOR FOR FLOATATION OF FLUORITE ORES Russian patent published in 2008 - IPC B03D1/14 

FIELD: mining industry; other industries; devices for concentration of minerals.

SUBSTANCE: invention is pertaining to concentration of minerals, in particular, to floatation of fluorite ores and is intended for industrial use at the concentration mills. Invention allows to reduce number of recleanings, to realize the flotation process in the cold mash, to simplify significantly flowsheet of the floatation concentration of fluorite ores and to reduce the power input and economical expenditures. In the capacity of the collector use dialkylarylpolyethyleneglycol ethers of the phosphoric acid of the general formula: [RC₆H₄O(CH₂CH₂O _m]₂P(O)OM, where R is alkyl C_nН_2n+1, n=6-9, m=4-12, М=Н, K,HN (CH₂CH₂OH)₃.

EFFECT: invention ensures the reduced number of recleanings, realization of flotation process in the cold mash, significant simplification of the flowsheet of the floatation concentration of fluorite ores, the reduced power input and economical expenditures.
