The invention relates to a method for comprehensively recovering valuable metals from electroplating waste mud. The method comprises the following steps of: leaching valuable metals contained in the electroplating waste mud by dilute sulphuric acid, and filtering and separating out acid-leaching slag and a filtrate; replacing copper ions in the filtrate by metallic iron, and filtering and separating copper powder and a filtrate; adding an alkali solution in the filtrate, adding a polymeric flocculant, controlling the pH value of the solution and reacting, and filtering and separating ferric hydroxide and a filtrate; adding the alkali solution in the filtrate, controlling the pH value of the solution and reacting, and filtering to obtain a chromium precipitate and a filtrate; adding the alkali solution in the filtrate, controlling the pH value of the solution, and converting zinc and nickel in the solution to nickel carbonate and zinc carbonate; and dissolving a nickel-zinc coprecipitate ...

The invention relates to a method for extracting copper, nickel and cobalt intermediate products from copper and cobalt ore at low cost. The method comprises the following steps of: crushing copper and cobalt ore by using a crusher, grinding by using an ore gridding machine into powder with the particle size of less than or equal to 100 meshes; placing the ore powder with the particle size of less than or equal to 100 meshes in a reaction kettle, performing agitation leach by using hydrochloric acid at normal temperature and normal pressure, and allowing copper, nickel, cobalt, iron, magnesium, and calcium in a form of chloride in the ore to enter lixivium; adjusting the pH value to be 0.5 to 1.5, and adding iron powder in an amount which is not less than 1.5 times that of the copper in the solution and replacing to remove copper; dropwise adding ammonia water and hydrogen peroxide simultaneously at the temperature of 90DEG C with continuous stirring to adjust the pH and ferrous oxide ions ...

The invention relates to a new process for purifying and refining coarse fluorene. The new process comprises the following steps: first, adding fluorene with the mass content of 60 to 70 percent and an organic solvent in a mass ratio of 1:1 into a reaction kettle, stirring for 40 to 60 minutes at normal temperature at the stirring speed of 30 to 90r/min, and performing suction filtration and drying to obtain industrial fluorene with the mass content being over 80 percent; then, adding the industrial fluorene into the reaction kettle according to the proportion that the ratio of organic solvent to water to the industrial fluorene is 0.5:0.5:1, then adding the organic solvent and the water, turning on a program heating and cooling control device for heating the mixture, starting a stirring machine for stirring 40 to 60 minutes at the stirring speed of 30 to 90 r/min, heating to 90+/-2 DEG C until the industrial fluorene is dissolved completely; turning off the stirring machine, adjusting ...
