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

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.
