Abstract
The invention discloses a mineral separation activating agent used in the lepidolite flotation process. Lepidolite concentrates float from tantalum-niobium tailings. The mineral separation activating agent is one or more of sulfate, carbonate and/or nitrate of copper, aluminum and lithium. A collecting agent is coconut oil primary amine and mixed with hydrochloric acid at the mass ratio of 1:1 to 1:5, an aqueous solution with the mass fraction of amine ranging from 0.5% to 5% is prepared to serve as a flotation reagent, the flotation reagent is added to the mineral separation activating agent, and the use amount of the flotation reagent ranges from 50 g/t to 100 g/t. In flotation, the solid content of tantalum-niobium tailings ranges from 20% to 30%, and the pH value of ore pulp ranges from 5 to 9 and is adjusted through sodium carbonate. By the adoption of the mineral separation activating agent, the flotation recycling rate of the lepidolite concentrates is increased.
