Abstract

The process of obtaining ammoniated superphosphate and liquid NP-fertilizer by phosphorus-sulphuric acid processing of washed and burned phosphorus concentrate (WBPC) in one cycle were studied. It has been established that at ratios of 100 : 5÷10 : 15 the compositions of ammoniated superphosphate samples are characterized as follows (wt., %): Р2О5total(t.). - 20.60-24.85; Р2О5free - absent; Р2О5acceptable by citric acid(ac.c.a.):Р2О5t. = 91.03-100; Р2О5water.solubility(w.s.). : Р2О5t. = 78.87-96.86; N - 4.20-4.79; pH - 2.95-3.17. The product is mainly from calcium sulfate di- and hemihydrate, mono-ammonium phosphate, mono- and dicalcium phosphate, quartz and activated fluorocarbonate apatite. A liquid NP fertilizer consists of 3.22-4.49% N, 16.92-17.75% P2O5, 2.18-2.86% CaO, 0.09-0.19% MgO, 0.5 -0.6% SO3, 0.10-0.11% Fe2O3, 0.003-0.007% Al2O3, while Р2О5ac.c.a.:Р2О5t. = 97.75-100% and Р2О5w.s.: Р2О5t. = 96.93-100%. The material balance of obtaining ammoniated superphosphate and liquid NP-fertilizer in one cycle is calculated. It has been shown that the ammonization of phosphorus-sulfuric acid phosphate pulp results in the maximum precipitation of insoluble components in the form of complex salts, which ensures the production of a purified liquid complex fertilizer for drip irrigation.

基于硫酸和磷酸混合物分解水洗干燥浓缩物的氨化过磷酸钙和液态氮磷化肥

研究了通过磷-硫酸处理洗涤和焚烧磷精矿（WBPC），在一个循环中获得氨化过磷酸钙和液体氮磷钾肥的过程。结果表明，在比例为 100 : 5÷10 : 15 的情况下，氨化过磷酸钙样品的成分特征如下（重量百分比）：Р2О5total(t.).- 20.60-24.85; Р2О5free - absent; Р2О5acceptable by citric acid(ac.c.a.):Р2О5t. = 91.03-100; Р2О5water.solubility(w.s.).:Р2О5t.=78.87-96.86；N - 4.20-4.79；pH - 2.95-3.17。产品主要来自二水和半水硫酸钙、磷酸一铵、磷酸一钙和磷酸二钙、石英和活性氟碳磷灰石。液体氮磷钾肥由 3.22-4.49%的 N、16.92-17.75%的 P2O5、2.18-2.86%的 CaO、0.09-0.19%的 MgO、0.5-0.6% SO3、0.10-0.11% Fe2O3、0.003-0.007% Al2O3，而 Р2О5ac.c.a.:Р2О5t. = 97.75-100% 和 Р2О5w.s：Р2О5t.=96.93-100%。计算了在一个循环中获得氨化过磷酸钙和液体氮磷钾肥的物料平衡。结果表明，磷硫酸磷酸盐浆的氨化能最大限度地以复合盐的形式析出不溶性成分，从而确保生产出用于滴灌的纯化液体复合肥。
