摘要： A process for producing low-fluorine calcium phosphate granules comprises a special roasting process in which the granules are heated to a temperature sufficient to expand the granules and evolve volatile fluorine compounds. The product resulting from the process according to the invention has a higher proportion of phosphorus than the granules from which it is produced, mixes well with conventional feeds, and exhibits good biological availability. The product is also useful as insulation. Processes are also disclosed for reducing the fluorine content of the phosphoric acid used to make the granules. The fluorine content of phosphoric acid can be reduced by precipitating fluorine salts from already-produced phsophoric acid in the presence of hydrochloric acid or by digesting phosphate rock with recycled phosphoric acid and hydrochloric acid to produce low-fluorine phosphoric acid directly. In either embodiment, reactive silica is used. Low-cost reactive silica can be made from vitreous crystalline silica by using the roasting process, eliminating the need for costly diatomaceous silica.
摘要翻译：一种生产低氟磷酸钙颗粒的方法包括特殊的焙烧过程，其中将颗粒加热到足以膨胀颗粒并放出挥发性氟化合物的温度。由根据本发明的方法产生的产物具有比其生产的颗粒更高的磷比例，与常规饲料良好地混合，并且表现出良好的生物利用度。该产品也可用作绝缘材料。还公开了用于降低用于制备颗粒的磷酸的氟含量的方法。磷酸的含量可以通过在盐酸的存在下从已经生成的phophoric酸中沉淀出氟盐，或通过用再循环的磷酸和盐酸消化磷酸盐岩，直接生成低氟磷酸，可以降低。在任一实施方案中，使用反应性二氧化硅。低成本的反应性二氧化硅可以通过使用焙烧工艺由玻璃状结晶二氧化硅制成，而不需要昂贵的硅藻土。

摘要： A method of removing heavy metals, particularly cadmium, from wet-process phosphoric acid produced by digesting raw phosphoric material with sulphuric acid, by precipitating out the heavy metals in sulphide form. The residual sulphuric acid is removed first by neutralization with alkali or as a not-readily dissolved sulphate precipitate. Alkali is added to obtain an Me/P ratio within the range of about 0.05-0.3, where Me is the number of cation equivalents in the alkali and P is the number of phosphorous atoms in the phosphoric acid, whereafter the heavy metals are precipitated out by adding a sulphide compound which is soluble in the phosphoric acid, and the sulphide precipitate removed.

摘要： Phosphorus pentoxide production with fluorine management includes collecting phosphorus from kiln off gas as phosphoric acid containing fluorine and reacting the fluorine in the phosphoric acid with reactive silica to yield fluorosilicic acid. The fluorosilicic acid is removed from the collected phosphoric acid. Fluorine management includes discharging from the kiln a residue containing processed agglomerates and heating the discharged, processed agglomerates and releasing fluorine therefrom. The released fluorine is reacted with reactive silica to yield fluorosilicic acid and the fluorosilicic acid is collected. Fluorine management includes forming a reducing kiln bed with feed agglomerates below a reducing freeboard. Kiln off gas is generated containing phosphorus in the form of elemental phosphorus a) oxidized outside of the kiln to phosphorus pentoxide and collected as phosphoric acid, b) collected as elemental phosphorus, or c) both.
