Abstract
Изобретение относитс к области переработки отходов цветной металлургии и технологии получени неорганических пигментов. Цель изобретени - повышение чистоты цвета, диспергируемости и дисперсности пигмента. В розит ввод т раствор мочевины при массовом отношении розита и мочевины 1:(0,01-0,02), затем смесь гранулируют до размера частиц 1-3 мм, после чего провод т термообработку при 500-900°С, промывку и сушку продукта. 1 табл.The invention relates to the field of recycling non-ferrous metallurgy and the technology of inorganic pigments. The purpose of the invention is to increase the purity of the color, dispersibility and dispersion of the pigment. A solution of urea is introduced into rosit with a mass ratio of rosit and urea 1: (0.01-0.02), then the mixture is granulated to a particle size of 1-3 mm, after which heat treatment is performed at 500-900 ° C, washing and drying product. 1 tab.
Description
Изобретение относитс к переработке отходов цветной металлургии и технологии получени неорганических пигментов.The invention relates to the recycling of non-ferrous metallurgy wastes and the production of inorganic pigments.
Цель изобретени - повьппение чистоты цвета, диспергируемости и дисперсности пигмента.The purpose of the invention is to increase the purity of the color, dispersibility and dispersion of the pigment.
Пример 1 (прототип). Калиевый розит, полученньм при очистке цинковых растворов от железа, который содержит, %: калий 8,1; железо 30; .сера 13; цинк 0,15, в количестве 500 г смешивают со стехиометрическим количеством едкого кали (157 г) и прокаливают при 800 С в. течение 2ч. Прокаленный продукт промьшают водой при . После промывки и сушки го- товьй пигмент размалывают на дис- мембратореExample 1 (prototype). Potassium rosit, obtained by cleaning zinc solutions from iron, which contains,%: potassium 8,1; iron 30; .sera 13; Zinc 0.15, in an amount of 500 g, is mixed with a stoichiometric amount of potassium hydroxide (157 g) and calcined at 800 ° C. for 2 hours The calcined product is rinsed with water at. After washing and drying, the prepared pigment is ground on a disperser.
Пример 2. Калиевый розит, аналогичный по составу примеру 1, гранулируют с введением в процессеExample 2. Potassium rosit, similar in composition to example 1, is granulated with the introduction in the process
его гранул ции мочевины с концен- трацией 300 г/л в количестве 2 мас.% (отношение розита к мочевине 1:0,02). Полученные гранулы розита размером 1-3 мм прокаливают при 800°С. Прокаленный продукт промьшают водой при 50 С. После промывки и сушки готовьй пигмент размалывают на дисмембрато- ре.its granulation of urea with a concentration of 300 g / l in an amount of 2 wt.% (rosit to urea ratio 1: 0.02). The resulting rositol granules of 1-3 mm in size are calcined at 800 ° C. The calcined product is rinsed with water at 50 ° C. After washing and drying, the prepared pigment is ground on a dismembrator.
Пример 3. Калиевьй розит, аналогичный по составу примеру 1, гранулируют раствором мочевины (ЗОО г/л), отношение розита к мо- чевине 1-0,01. Полученные гранулы розита размером 1-3 мм прокаливают при 800 С и дальнейшую обработку ведут аналогично примеру 1.Example 3. Potassium rozit, similar in composition to example 1, is granulated with a solution of urea (ZOO g / l), the ratio of rosit to urea is 1-0.01. Rosite granules of 1-3 mm in size are calcined at 800 ° C and further processed as in Example 1.
Пример 4. Исходный розит гранулируют аналогично примеру 2, отношение розита к мочевине 1: : 0,015. Полученные гранулы розита размером 1-3 мм прокаливают приExample 4. Initial rosite is granulated analogously to example 2, the ratio of rosit to urea is 1:: 0.015. Rosite granules obtained size of 1-3 mm calcined at

Пример 5 (вне количествен- ных пределов предлагаемого способа). Гранул ци розита аналогична примеру 2 отношение розита к мочевине 1:0,008о Дальнейша обработка аналогична примеру 1,Example 5 (outside the quantitative limits of the proposed method). Rosite granulation is similar to example 2: 1: 0.008 to rosit to urea. Further processing is similar to example 1,
Пример 6 (вне количествен- ных пределов предлагаемого способа). Гранул ци розита аналогична примеру 2, отношение розита к мочевине 1:0,024, Дальнейша обработка аналогична примеру КExample 6 (outside the quantitative limits of the proposed method). Rosite granulation is similar to Example 2, rositol to urea ratio is 1: 0.024, Further processing is similar to Example K
