Description
Изобретение касаетс переработки фосфатного сырь и хлорида .кали на концентрированное бесхлорное калийно-фосфорное удобрение .The invention relates to the processing of phosphate raw materials and potassium chloride for concentrated chlorine-free potassium phosphate fertilizer.
Известен способ получени бесхлорного калийного удобрени путем обработки смеси фосфатного сырь с хлористым калием фосфорной (КИСЛОТОЙ с последующим высушиванкем получелпюй пульпы.A known method for producing chlorine-free potassium fertilizer is by treating a mixture of phosphate raw materials with potassium chloride phosphate (ACID, followed by drying the pulp.
Предложенный способ отличаетс от известного способа тем, что высушенную пульпу прокаливают при 400-600°С. Это способствует получению удобрени -т.риметафосфата с повышенным содержанием питательных элементов .The proposed method differs from the known method in that the dried pulp is calcined at 400-600 ° C. This contributes to the production of fertilizer, t.rimetaphosphate with a high content of nutrients.
Дегидратируюсь, кислые соли образуют трйметафосфат Са(П2РО4)2 + КНоРО4 - KCaPaOg+SHvO, имюп1ий кольцевое строение . Измен соотношение КС1: Саз(Р0.1)2: : согласно ура-виелию: Саз(РО4)2-Ь +24КС14-16НзР04 Са(К4РзО1о)2- -24НС1 + + 12Н2О можнополучать разли41ные продукты.I dehydrate, the acid salts form trimetaphosphate Ca (P2PO4) 2 + KNOPO4 - KCaPaOg + SHvO, an impely ring structure. Change the ratio of КС1: Саз (Р0.1) 2:: according to ura-vielium: Саз (РО4) 2-Ь + 24КС14-16НзР04 Са (К4РзО1о) 2- -24НС1 + + 12Н2О can receive different products.
Пример 1. 100 г фосфорита Каратау смешивают с 57 г КС1 Ббрезниковского месторождени и обрабатывают .при комнатной температуре 298 г (71,7%). Полученную массу нагревают в интервале температур 400-Example 1. 100 g of Karatau phosphorite are mixed with 57 g of KS1 of the Bbreznikovsky field and treated at room temperature with 298 g (71.7%). The resulting mass is heated in the temperature range 400-
600°С в течение 1-2 час до полного удалени воды. Продукт содержит 63,9% , из них 15,3-в воднорастворимой форме и 11,8% К2О.600 ° C for 1-2 hours until complete removal of water. The product contains 63.9%, of which 15.3 is in water-soluble form and 11.8% K2O.
Пример 2. 100 г фосфорита Каратау смешивают с 114 г КС1 и обрабатывают 403 г ПзРО4 (71,7%). Полученную массу .нагревают при 400-600°С. Продукт содержит 17% К2О, 63% Р2О5 ИЗ них 40%-В воднорастворимой форме.Example 2. 100 g of Karatau phosphorite is mixed with 114 g of KC1 and treated with 403 g of PzRO4 (71.7%). The resulting mass is heated at 400-600 ° C. The product contains 17% K2O, 63% P2O5, 40% of which are in water-soluble form.
Пример 3. 100 г руды смешиваютс с 455 г КС1 и обрабатывают 61,7 г ПзРО4 (71,7%). Полученную массу нагревают при 400°С до полного обезвоживани . Продукт содержит 44% цитратно-растворимого PoOs, из них 40% водного, 3% KiO и 6-7% хлора.Example 3. 100 g of ore are mixed with 455 g of KC1 and treated with 61.7 g of PzRO4 (71.7%). The resulting mass is heated at 400 ° C until complete dehydration. The product contains 44% citrate-soluble PoOs, of which 40% is water, 3% KiO and 6-7% chlorine.
