Embodiment 1
[0021] Such as figure 1 As shown, the manganese ore industrialized wet ball milling method based on electrolytic manganese anolyte adopts three-stage closed-circuit wet grinding, and the steps include:
[0022] Step 1, 1kg manganese ore (including the following mass percentage components: Mn18.32% (main phase is MnCO 3 ), Fe 2 o 3 2.14%, MgO3.54%, CaO6.2% and SiO 2 25.5% etc.) are crushed to less than 10mm, and then the electrolytic manganese anolyte (the electrolytic manganese anolyte contains sulfuric acid 30g / L) is used to adjust the slurry to 80wt%. Ball milling until the particle size of the manganese ore is below 80 mesh accounts for 90%, and the unqualified manganese ore after the primary classification is returned to the primary wet ball mill;
[0023] Step 2. Slurry the manganese ore below 80 mesh obtained in step 1 to 70wt% with the electrolytic manganese anolyte, and perform secondary wet ball milling under the conditions of a rotating speed of 40r / min and a bal...
Embodiment 2
[0027] Such as figure 1 As shown, the manganese ore industrialized wet ball milling method based on electrolytic manganese anolyte adopts three-stage closed-circuit wet grinding, and the steps include:
[0028] Step 1, 1kg manganese ore (including the following mass percentage components: Mn19.4% (main phase is MnCO 3 ), Fe 2 o 3 2.67%, MgO4.12%, CaO5.9% and SiO 2 22.4% etc.) are broken to less than 25mm, and then the electrolytic manganese anolyte (electrolytic manganese anolyte containing sulfuric acid 50g / L) is used to adjust the slurry to 85wt%. Ball milling until the particle size of the manganese ore is below 80 mesh accounts for 90%, and the unqualified manganese ore after the primary classification is returned to the primary wet ball mill;
[0029] Step 2. Slurry the manganese ore below 80 mesh obtained in step 1 to 75wt% with electrolytic manganese anolyte, and perform secondary wet ball milling until the particle size of the manganese ore is below 120 mesh at a r...
Embodiment 3
[0033] Such as figure 1 As shown, the manganese ore industrialized wet ball milling method based on electrolytic manganese anolyte adopts three-stage closed-circuit wet grinding, and the steps include:
[0034] Step 1, 1kg manganese ore (including the following mass percentage components: Mn20.1% (main phase is MnCO 3 ), Fe 2 o 3 1.98%, MgO4.07%, CaO7.1% and SiO 2 25.6% etc.) are broken to less than 15mm, and then the electrolytic manganese anolyte (the electrolytic manganese anolyte contains sulfuric acid 40g / L) is used to adjust the slurry to 82wt%. Ball milling until the particle size of the manganese ore is below 80 mesh accounts for 90%, and the unqualified manganese ore after the primary classification is returned to the primary wet ball mill;
[0035] Step 2. Slurry the manganese ore below 80 mesh obtained in step 1 to 72wt% with electrolytic manganese anolyte, and perform secondary wet ball milling until the particle size of the manganese ore is below 120 mesh at a...
