    Abstract: Phosphorus furnaces were operated by the Tennessee Valley Authority (TVA) to produce elemental phosphorus beginning over the period 1936-1976. Elemental phosphorus was lost in phosphorus-containing waste throughout the 40 years TVA produced the element. Large quantities of phosphorus-containing wastes remain at the site where TVA produced the chemical.Technology has not been available to treat phosphorus-containing waste so as to recover elemental phosphorus and produce an innocuous waste material. White phosphorus is a dangerous chemical and it is very toxic. Essentially all the elemental phosphorus must be recovered if an innocuous waste is produced. Commercial processes have not been available to recover elemental phosphorus from phosphorus-containing wastes.Elemental phosphorus is produced commercially by smelting phosphatic material in electric furnaces. A process has been invented to prepare phosphatic feedstock from phosphorus-containing waste. The waste is heated in a temperature range which will volatilize white phosphorus and convert white phosphorus into red phosphorus. Thus phosphorus-containing wastes can be safely agglomerated to prepare phosphatic feedstock. Feedstock is heated to approximately 2700.degree. F. in electric furnaces and red phosphorus is vaporized. White phosphorus is obtained when phosphorus vapor is condensed.

    Abstract translation: 磷酸炉由田纳西河谷管理局（TVA）运营，以在1936 - 1976年期间开始生产元素磷。 元年磷在含磷废物中丧失，整个40年来，TVA产生了这一元素。 在TVA生产化学品的场所，大量含磷废物仍然存在。 技术还没有可用于处理含磷废物，以回收元素磷并产生无害废物。 白磷是一种危险的化学物质，毒性很大。 如果产生无害废物，基本上必须回收所有的元素磷。 从磷含量废物中回收元素磷的商业过程尚不可用。 元素磷通过在电炉中熔化磷酸盐材料而商业化生产。 已经发明了一种从含磷废物制备磷酸盐原料的方法。 废物在使白磷挥发并将白磷转化为红磷的温度范围内加热。 因此，含磷废物可以安全地聚集以制备磷酸盐原料。 原料在电炉中加热至约2700°F，红磷蒸发。 当磷蒸气冷凝时，得到白磷。

    Abstract: Processes are disclosed for recovering solid wastes containing elemental phosphorus. The wastes may cause serious environmental problems at phosphorus furnaces because elemental phosphorus is toxic to marine animals. Recovery of the wastes was considered for the following.1. At phosphorus furnace plants making phosphoric acid as one of the products, when the objective is to produce only high-quality phosphoric acid.2. At phosphorus furnace plants making elemental phosphorus as a final product, and the objective is to produce only high-quality phosphorus.3. At plant sites where neither phosphoric acid nor phosphorus is produced.The processes include recycling the wastes to phosphorus furnaces. All of the phosphorus acid produced in 1 can be highly concentrated with low impurities content. In 2, all the low-quality phosphorus is recycled to the phosphorus furnaces and all the product is high grade. In 3, phosphorus furnaces are not available at the plant site and recycling the solid wastes is impractical. In this case processes are disclosed for recovering the elemental phosphorus from the waste, converting the residue to granular fertilizer, and making suspension fertilizer from water containing elemental phosphorus.

    Abstract translation: 公开了用于回收含有元素磷的固体废物的方法。 由于元素磷对海洋动物有毒，废弃物可能对磷炉造成严重的环境问题。 以下考虑废物的回收。 在磷化炉厂将磷酸作为产品之一，目的是生产优质磷酸。 2.磷化炉生产元素磷作为最终产品，目的是生产优质磷。 3.在不生产磷酸和磷的植物地点。 这些过程包括将废物回收到磷炉。 1中产生的所有磷酸都可以高度浓缩，杂质含量低。 2，所有低质量的磷被回收到磷炉，所有的产品都是高档的。 3，磷厂在厂址不可用，而且固体废物的再循环是不切实际的。 在这种情况下，公开了用于从废物中回收元素磷的过程，将残余物转化为颗粒肥料，并从含有元素磷的水中制备悬浮肥料。
