ECOLOGICALLY CLEAN IRON VITRIOL NEUTRALISER AND METHOD OF USING SAID NEUTRALISER |
摘要 |
FIELD: chemistry. ^ SUBSTANCE: iron vitriol is neutralised with an ecologically clean neutraliser which contains calcium-containing material in form of metallurgical slug of the following composition, wt %: CaO 32.1-48.3; MgO 5.6-11.7; SiO2 7.1-18.5; Fe2O3 6.6-16.0; MnO 1.3-5.8 with particle size of 0-300 mm. The method of neutralising iron vitriol involves addition of neutralising calcium-containing material, wherein neutralisation is carried out by layerwise stacking of iron vitriol with calcium-containing metallurgical slag in ratio of 1:5. ^ EFFECT: invention enables complete self-neutralisation of wastes, reduces cost and simplifies the neutralisation technology and is environmentally friendly. ^ 2 cl, 1 ex |
