Titanium ore flotation pretreatment and titanium separation method

The invention provides a titanium ore flotation pretreatment and titanium separation method, and relates to the technical field of titanium ore flotation. The titanium ore flotation pretreatment and titanium separation method comprises the following specific steps that firstly, ore crushing is conducted, specifically, raw ore is crushed through a crusher till the diameter is smaller than 2 mm, ore particles are formed, and the ore particles are ground into ore powder with the diameter ranging from 0.1 mm to 0.2 mm through a powder making machine; 2, ore powder pulping, wherein water is added into the ore powder prepared in the step 1 to be mixed, and ore pulp is prepared; 3, primary separation with strong magnetism, wherein the prepared ore pulp is subjected to magnetic separation through a wet magnetic separator, and titanium middlings are obtained; and fourthly, primary separation is conducted on a table concentrator, specifically, the prepared titanium middling is subjected to primary separation through th
