Способ осуществл ют разложением цеолитсодержащего сырь раствором, образующимс при азотнокислом выщелачивании бедных фосфоритовых руд. Дл обеспечени повышенной адсорбционной способности цеолитов в отношении фосфат-ионов в раствор ввод т соли кали до 1,5 - 2,0 мас.%. Калийфосфоразотнокислый раствор нейтрализуют аммиаком до PH 5,5 - 6,2, а затем этой смесью обрабатывают цеолитсодержащее сырье при соотношении Т:Ж = 1:20-22 и температуре 90 - 105°С. 1 табл.The invention relates to the production technology of mineral phosphate fertilizers from zeolite-containing raw materials and allows increasing the content of P 2 O 5 in it in the water-soluble and citrate-soluble forms. The method is carried out by decomposing a zeolite-containing raw material with a solution resulting from the nitric leaching of lean phosphate ores. To provide an increased adsorption capacity of zeolites with respect to phosphate ions, potassium salts are introduced into the solution up to 1.5-2.0 wt.%. The potassium phosphorate acid solution is neutralized with ammonia to PH 5.5 - 6.2, and then zeolite-containing raw materials are treated with this mixture at a ratio T: W = 1: 20-22 and a temperature of 90 - 105 ° C. 1 tab.
Description
Изобретение относитс к технологии минеральных удобрений и может быть использовано дл производства фосфорных удобрений из цеолитсодержащего сырь .This invention relates to a technology of mineral fertilizers and can be used for the production of phosphate fertilizers from zeolite-containing raw materials.
Целью изобретени вл етс повышение содержани в удобрении s в водорастворимой и цитратнорастворимой формах.The aim of the invention is to increase the content of fertilizer s in water-soluble and citrate-soluble forms.
Способ осуществл ют-разложением цеолитсодержащего сырь раствором, образующимс при азотнокислом выщелачивании бедных фосфоритовых руд и содержащим, мас.%: 5,5-6,0; СаО 8,8-8,9; MgO 0,10-0,12; ЖЦ 9,9- 10,2; H/jO - остальное1. Дл обеспече-, ни повышенной адсорбционной способности цеолитов в отношении фос- фатионов, в раствор ввод т соли кали (КС1 и KfS04) до 1,5-2,0 мас.% в пересчете на К4. Калийфосфораэотнокислый раствор нейтрализуют аммиаком до рН 5,5-6,2, а затем этой смесью обрабатывают цеолитсодержащее сырье при соотношении (20-22) и температуре 90-105°С.The method is carried out by decomposing the zeolite-containing raw material with a solution formed during the nitric leaching of poor phosphate ores and containing, in wt.%: 5.5-6.0; CaO 8.8-8.9; MgO 0.10-0.12; Life cycle 9.9- 10.2; H / jO - the rest1. To ensure the increased adsorption capacity of zeolites with respect to phosphate, potassium salts (KC1 and KfS04) are introduced into the solution up to 1.5-2.0 wt.% Based on K4. The potassium phosphorus acid solution is neutralized with ammonia to a pH of 5.5-6.2, and then the zeolite-containing raw material is treated with this mixture at a ratio of (20-22) and a temperature of 90-105 ° C.
Пример осуществлени способа. 100 г цеолитового туфа обрабатывают 2000 мл () калийфосфор- азотнокислого раствора, нейтрализованного аммиаком, при рН 5,5 и температуре 90°С. Обработку ведут 1 ч, пос- ле чего суспензию фильтруют, осадок на фильтре промывают водой в объеме, равном объему рабочего раствора, сушат и получают удобрение со следующим содержанием РгОумас.%: . 14,9, в том числе УСВ. 93,4; РаОр вод„ 77,6; РаО цит. 15,8.An example of the method. 100 g of zeolite tuff are treated with 2000 ml of () potassium phosphate-nitric acid solution, neutralized with ammonia, at pH 5.5 and at a temperature of 90 ° C. The treatment is carried out for 1 h, after which the suspension is filtered, the filter cake is washed with water in a volume equal to the volume of the working solution, dried and a fertilizer is obtained with the following RgOmass.% Content:. 14.9, including SPM. 93.4; Water color “77,6; Rao tsit. 15.8
