Preparation method of copper-lead-zinc ore partial bulk flotation regulator containing secondary copper sulfide

A preparation method of a copper-lead-zinc ore partial bulk flotation regulator containing secondary copper sulphide comprises the following steps: firstly, adding hexamethylenetetramine and ferrous nitrate into an organic solvent ethylene glycol monoethyl ether, and fully carrying out nitrolysis reaction at the temperature of 0-20 DEG C to obtain a solvent A with relatively strong solubility; adding sodium pyrosulfite, zinc sulfate and a catalyst ammonium ferrous sulfate into the solvent A, heating, and stopping heating after solids are completely dissolved to obtain a solution B; and adding sodium hydroxide into the solution B, uniformly stirring, quickly cooling to-20-0 DEG C, separating out solids in the cooling process, filtering, collecting the solids, and repeatedly washing the solids with deionized water to obtain the copper-lead-zinc ore partial bulk flotation regulator containing secondary copper sulphide. The prepared regulator can effectively reduce mutual content of copper, lead and zinc in parti
