Method for treating nickel sulfide ore biological heap leaching solution

The invention discloses a method for treating nickel sulfide ore biological heap leaching solution, which relates to nickel sulfide ore, in particular to a method for recovering valuable metals from high-magnesium high-iron nickel sulfide ore biological heap leaching solution. The method is characterized by comprising the following steps of: adding lime into the biological heap leaching solution for pulpifying, introducing air for oxidization reaction, oxidizing Fe in the biological heap leaching solution into Fe, hydrolyzing to generate Fe(OH)3, and performing the adsorption recovery of the valuable metals such as nickel, cobalt and copper in an ion exchange column. Normal temperature iron deposition is realized with low energy consumption; valuable metal ions in the treated heap leaching solution can be lowered to below 3ppm; and the recovery rates of the valuable metal ions are high, and both the recovery rates of the nickel and cobalt metal ions are over 99 percent. The method has low treatment co
