The invention relates to a spodumene ore beneficiation method which comprises the steps that spodumene ore is subjected to ore grinding and grading in sequence, and coarse-grain ore and fine-grain ore are obtained; the obtained coarse ore is sequentially subjected to chute roughing and table concentration, and spodumene concentrate A is obtained; desliming the obtained fine ore to obtain slime and settled sand, and carrying out flotation on the settled sand to obtain spodumene concentrate B; the spodumene concentrate A and the spodumene concentrate B are mixed to obtain spodumene concentrate; the flotation comprises rough flotation, fine flotation and scavenging; a collecting agent used in flotation is prepared from sulfonated oleic acid, alkyl carboxyl hydroximic acid, fatty alcohol-polyoxyethylene ether and octanol in parts by weight through saponification treatment. According to the beneficiation method, the rough and fine processing combined process of ore grinding, rough and fine grading, coarse grain gr
