Description
Известные способы получени цинковых белил кз растворов предполагают процесс Быщелачпвакн цинка нз цинкосодержащих продуктов серной кислотой и. очистку полученных растворов известными в гидрометаллургии цинка методами. При этом получение белил св зано с пзреводом кислоты в гипс или с выпуском попутно дешевого сульфата аммони .Known methods for the preparation of zinc oxide kz solutions involve the Bypass process of zinc and zinc-containing products with sulfuric acid and. purification of the obtained solutions by methods known in zinc hydrometallurgy. The production of white is associated with the conversion of the acid into gypsum or with the release of cheap ammonium sulphate.
Получаемые из растворов белила известными способами не удовлетвор ют требовани м лакокрасочной и резиново промышленности.The whitewash obtained from solutions by known methods does not satisfy the requirements of the paint and varnish and rubber industries.
Способ получени цинковых белил, согласно изобретению, лишен указанных недостатков и заключаетс в том, что цинковый огарок, велцокислы и любые другие продукты, содержащие цинк в виде окиси, подвергают выщелачиванию растворами хлористого кальци при действии углекислого газа по реакции: ZnO(CdO)-hCaCl2 + .-. (CdCla)-h + СаСОз.The method for producing zinc oxide according to the invention is free from the indicated drawbacks and is that zinc calcine, bicycle acids and any other products containing zinc as oxide are leached with calcium chloride solutions under the action of carbon dioxide by the reaction: ZnO (CdO) -hCaCl2 + .-. (CdCla) -h + CAS02.
Полученный раствор подвергают очистке от кадми и свинца известными методами.The resulting solution is purified from cadmium and lead by known methods.
Предмет изобретени Subject invention
Способ иолучени цинковых белил из материалов, содержащих цинк в окисленной форме, нутем выщелачивани его растворами неорганических соединений, отличающийс тем, что, с целью обеспечени мал рных свойств получаемых цинковых белил, дл выщелачиван1 и окиси цинка примен ют .раствор хлористого кальци с последующей обработкой полученного продукта известными методами.The method of obtaining zinc oxide from materials containing zinc in an oxidized form by chipping its leaching with solutions of inorganic compounds, characterized in that, in order to ensure the small properties of the zinc oxide obtained, the calcium chloride solution is used for leaching and zinc oxide with the subsequent processing of the obtained product known methods.
