Description
Изобретение относитс к области получени сложных комплексных удобрений, содержащих в усва емой форме одновременно фосфор и магний.The invention relates to the field of producing complex complex fertilizers containing, in an absorbable form, both phosphorus and magnesium.
Известен способ получени сложных фосфорных удобрений путем обработки фосфорита фосфорной кислотой с последующим высущиванием образовавщейс жидкой шихты и ее плавлением.A known method for producing complex phosphorus fertilizers by treating phosphate with phosphoric acid, followed by drying the resulting liquid mixture and melting it.
Недостатками известного способа вл ютс гигроскопичность полученного удобрени и невысокое содержание усво емого PgOs «55%).The disadvantages of this method are the hygroscopicity of the obtained fertilizer and the low content of digestible PgOs (55%).
Предложенный способ отличаетс от известного тем, что в жидкую щихту ввод т серпентин . Это способствует получению сложного магнийсодержащего удобрени с повыщенным содержанием цитратнорастворимой формыThe proposed method differs from the known one in that serpentine is introduced into the liquid grinder. This contributes to the production of complex magnesium-containing fertilizer with an increased content of citrate-soluble form.

Пример. Дл получени сложного метафосфатного удобрени используют фосфорит Каратау (25-28% Р2О5), реактивную фосфорную кислоту (20-40%-ную) и серпентин - отход Джетыгаринского асбестового комбината с минералогическим составом (в %): асбест 26; серпентин 5; карбонаты 4; кварц 5; магний 6; глина 4; химический состав (в %): 30,03 MgO; 30,33 SiO2.Example. To obtain a complex metaphosphate fertilizer, Karatau phosphorite (25-28% P2O5), reactive phosphoric acid (20-40%) and serpentine are used as waste products of the Dzhetygara asbestos combine with mineralogical composition (in%): asbestos 26; serpentine 5; carbonates 4; quartz 5; magnesium 6; clay 4; chemical composition (in%): 30.03 MgO; 30.33 SiO2.
