The invention provides a recovery method for titanium separation tailings. The recovery method comprises the following steps that fine-grained ore with the particle size lower than the preset particle size is separated from the titanium separation tailings; the fine ore is subjected to strong magnetic pre-enrichment, and enriched ore is obtained; the enriched ore is subjected to flotation through a non-transmission flotation technology, titanium concentrate is obtained, flotation comprises rough flotation, fine flotation and scavenging, and the non-transmission flotation technology comprises the following steps that the enriched ore and air are guided into a non-transmission flotation tank under the ore pressure, and a mixed phase is formed; the mixed phase is guided out, and foam on the surface of the mixed phase is collected. 本申请提供一种选钛尾矿的回收方法，包括如下步骤：从所述选钛尾矿分选出粒度低于预定粒度的细粒矿；将所述细粒矿进行强磁预富集，得到富集矿；通过无传动浮选工艺浮选所述富集矿，得到钛精矿，所述浮选包括粗选、精选和扫选，所述无传动浮选工艺包括如下步骤：将所述富集矿和空气在矿压下导入无传动浮选槽，形成混合相；导出所述混合相，收集混合相表面的泡沫。
