Abstract: Disclosed is a sodium petroleum sulfonate collector for fluorite flotation, comprising sodium petroleum sulfonate and non-polar oil, wherein the molar ratio of the non-polar oil to the sodium petroleum sulfonate is 3.33-5.67, the sodium petroleum sulfonate comprises raw material oil and active substance, the molecular weight of the raw material oil is 350-450, the molecular weight of the sodium petroleum sulfonate is 500-750, the aromatic hydrocarbon comprises benzene ring hydrocarbon and naphthalene ring hydrocarbon, the content of the benzene ring hydrocarbon is 5% to 11%, and the content of the naphthalene ring hydrocarbon is 5% to 5.2%, the raw material oil needs to be sulfonated by sulfur trioxide, and the molar ratio of the aromatic hydrocarbon to the sulfur trioxide in the raw material oil is 2.4 to 5. The sodium petroleum sulfonate collector proposed by this disclosure is both efficient and low temperature resistant.
