求翻译：由于我国合成氨和副产硫酸铵的产量较大，而且磷石膏中含有未分解的磷矿、氟化物及铁铝化合物、酸不溶物、有机质等多种杂质，使磷石膏与碳铵的转化过程变得较为困难，转化料浆的过滤及碳酸钙的洗涤指标受到影响。是什么意思？

Due to the larger production of synthetic ammonia and byproduct ammonium sulfate, and phosphogypsum contains the undecomposed rock phosphate, fluoride and iron-aluminum compounds, acid insoluble organic matter and other impurities, so that the transformation process of phosphogypsum and ammonium bic

Because of our synthetic ammonia and ammonium nitrate-sulfuric acid production is large, and Phosphor gypsum contains no decomposition of phosphorus and iron ore, aluminum fluoride compounds, insoluble in acid, organic impurities, such as the ammonium phosphate gypsum and the carbon of the conversio

Is big as a result of our country synthetic ammonia and the by-product ammonium sulfate output, moreover in the phosphorus gypsum does not include the decomposition phosphorus ore, the fluoride and the hard aluminum compound, the sour insoluble substance, the organic matter and so on many kinds of i

Because of my greater yield of ammonia and ammonium sulfate by-product, and decomposition of phosphogypsum contains no phosphate, aluminium fluoride and iron compounds, and other impurities Acid insoluble matter, organic matter, makes the conversion of phosphogypsum and Ammonium bicarbonate process
