FIELD: industrial production of new phosphorus-containing collecting agents for floatation concentration of minerals of sulfide and non-sulfide ores.
SUBSTANCE: collecting agents are produced by phosphorylation of oxyethylated higher alcohols with the aid of mixture of phosphorous oxychloride and methyl phosphonic acid dichloride at mole ratio of phosphorus oxychloride: methyl phosphonic acid dichloride=(1-n):n and oxyethylated higher alcohols:phosphorylating agent=(2-n) : 1, where n=0.1-0.4.
EFFECT: extended range of collecting agents; improved properties of agents; low cost of floatation process.
