Embodiment 1
[0047] Example 1 like Figure 1~5 As shown, a method for comprehensively recycling barium-containing waste slag in the production process of refined aluminum, the method is composed of fluoride ion recovery process, leachate separation process, iron-aluminum separation process, and sodium-barium separation process. in
[0048] The fluoride ion recovery process refers to firstly mixing the barium-containing waste slag and calcium chloride in the production process of refined aluminum according to the mass ratio of 1:0.2 to form a mixture and then pass it through the feeder 11 into the pickling tank 12, add water and stir evenly with an electric mixer, the hydrochloric acid from the hydrochloric acid storage tank Pump into pickling tank 12 in 14, every liter of mixed solution needs to add the hydrochloric acid that mass concentration is 36% to be 180 g, obtain pickling liquid after pickling 2.0 h; The ratio (kg / L) is 1:2; the pickling liquid is pumped into the filter...
Embodiment 2
[0052] Example 2 like Figure 1~5 As shown, a method for comprehensively recycling barium-containing waste slag in the production process of refined aluminum, the method is composed of fluoride ion recovery process, leachate separation process, iron-aluminum separation process, and sodium-barium separation process. in
[0053] The fluoride ion recovery process refers to first mixing the barium-containing waste slag and calcium chloride in the production process of refined aluminum at a mass ratio of 1: 1 to form a mixture and then pass it through the feeder 11 into the pickling tank 12, add water and stir evenly with an electric mixer, the hydrochloric acid from the hydrochloric acid storage tank Pump into pickling tank 12 in 14, every liter of mixed solution needs to add the hydrochloric acid that mass concentration is 36% to be 450 g, obtain pickling liquid after pickling 0.5 h; The ratio (kg / L) is 1: 10; the pickling solution is pumped into the filter press 1...
Embodiment 3
[0057] Example 3 like Figure 1~5 As shown, a method for comprehensively recycling barium-containing waste slag in the production process of refined aluminum, the method is composed of fluoride ion recovery process, leachate separation process, iron-aluminum separation process, and sodium-barium separation process. in
[0058] The fluoride ion recovery process refers to firstly mixing the barium-containing waste slag and calcium chloride in the production process of refined aluminum at a mass ratio of 1:0.6 to form a mixture and then pass it through the feeder 11 into the pickling tank 12, add water and stir evenly with an electric mixer, the hydrochloric acid from the hydrochloric acid storage tank Pump into pickling tank 12 in 14, every liter of mixed solution needs to add the hydrochloric acid that mass concentration is 36% to be 320 g, obtain pickling liquid after pickling 1.5 h; The ratio (kg / L) is 1:6; the pickling solution is pumped into the filter press ...
