Hydrochloric acid, also known as muriatic acid, is an aqueous solution of hydrogen chloride.It is a colorless solution with a distinctive pungent smell. It is classified as a strong acid.It is a component of the gastric acid in the digestive systems of most animal species, including humans. Hydrochloric acid is an important laboratory reagent and industrial chemical.
27-10-2019· Their phosphoric acid processes, however, are capable of producing an acid of far higher quality than that normally associated with fertilizer grade acid. Unground phosphate rock is fed into the first of a series of three dissolvers along with recycle HCl, a portion of the HCl feed, and CCD wash water.
The present paper deals with the treatment of phosphate obtained from a commercial sample of Akashat phosphate ore in hydrochloric acid. The factors studied are effects of the temperature of dissolution, acid concentration, and the time required for mixing phases. The experiments were performed with 100 kg/m 3 of solid/liquid ratio, the size of the particles ranged 125-140 µm, the initial ...
When phosphate rock is leached with hydrochloric acid, radium can be removed by co-precipitation with Ba0.4Ca0.6SO4 and uranium by extraction with a 5% solution of tributyl phosphate in hexane or Varsol. Phosphoric acid is then separated from calcium chloride solution and other impurities by extraction with undiluted tributyl phosphate. The lanthanides can be precipitated from the raffinate by ...
In this study, experiments have been carried out to reduce/eliminate carbonate content by leaching the ground phosphate rock with dilute hydrochloric acid solution. Effects of hydrochloric acid ...
Hydrochloric acid or muriatic acid is a colorless inorganic chemical system with the formula H 2 O:HCl. ment of the phosphate rock with the hydrochloric acid may be represented as follows: If six molecules of acid are used the reaction may be represented as follows: Sodium hydrogen phosphate react with hydrogen chloride to produce phosphoric ...
When phosphate rock is leached with hydrochloric acid, radium can be removed by co‐precipitation with Ba 0.4 Ca 0.6 SO 4 and uranium by extraction with a 5% solution of tributyl phosphate in hexane or Varsol. Phosphoric acid is then separated from calcium chloride solution and other impurities by extraction with undiluted tributyl phosphate.
phosphate rock with sulfuric acid or phosphoric acid. The acidulation process converts the highly insoluble phosphate in mineral apatite into forms which are available to plants, such as mono-calcium phosphate an£^ di-calcium phosphate CaHPO^. "When phosphate rock is treated with sufficient acid…
07-08-2019· As part of the valorization of the Moroccan phosphate rock by extraction of rare earths, different experiments on natural Moroccan phosphate from the Gantour Basin (basin of phosphate in the Youssoufia area) were done in the REMATOP laboratory. The response surface methodology was used to study the effects of the influence of different parameters (acid concentration, solid/liquid ratio ...

phosphate rocks. Hydrochloric acid can be used for the manufacture of phosphoric acid. Phosphoric acid manufactured from phosphate rock by this route is much purer than that produced by the sulphuric acid route. However, in addition to the difficulty of recovering phosphoric acid, there are other technical problems that must be overcome
Hydrochloric Acid in Hydrometallurgy Bepress. Phosphate rock is composed mainly of fluorapatite, hydroxyapatite, and carbonato-apatite. Phosphate rock occurs either as a sedimentary deposit, e.g., in Florida and North Africa, or as igneous rock, e.g., in Kola peninsula, Russia.
