The present invention is the method that decomposing phosphate rock by chlorhydric acid prepares phosphoric acid salt and phosphoric acid, proposes in order to overcome separation and two problems of blowdown of existing in the decomposing phosphate rock by chlorhydric acid technology, and this method is a circulation process.The core of method, be to prepare in the solution of phosphoric acid ...
May 01, 2002· Dissolution of calcium, phosphate, fluoride and rare earth elements (REEs) from a disc of natural fluorapatite mineral (FAP) in perchloric, hydrochloric, nitric, sulphuric and phosphoric acid solutions: A kinetic model and comparative batch leaching of major and minor elements from FAP and RE-FAP concentrate.
1. the method of recovering a substantially non-hygroscopic calcium phosphate product from phosphate rock containing calcium phosphate which comprises dissolving the phosphorous component of the rock in an inorganic nitrogenous acid with the resulting formation of an acidic aqueous phase containing substantially all of the acid-solubilized calcium and phosphorus components of the rock in the ...
method developed to extract P is the wet process to convert commercial phosphate rock into phosphoric acid. First phosphate rock is mined and beneficiated (crushing, milling, washing, flotation, sometimes calcination) to produce commercial phosphate rock. The P 2 O 5 recovery from this step varies from 25 to 90%, with average in the 70-80% ...
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 ...

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
Phosphate acidulation utilizing HF acid - US Patent 6676914 ..... or of an alkaline earth metal with hydrochloric acid or hydrofluoric acid in excess "as ... which uses sulfuric acid to digest the phosphate rock.)
phosphate) from low grade / waste phosphate rock. This approach is considered as simple and cost effective process for the development of uneconomically phosphate resources. Based on this process, phosphate rock is converted to phosphate salts (Di-calcium phosphate) through the following steps; Leaching using hydrochloric acid.
May 01, 2002· Dissolution of calcium, phosphate, fluoride and rare earth elements (REEs) from a disc of natural fluorapatite mineral (FAP) in perchloric, hydrochloric, nitric, sulphuric and phosphoric acid solutions: A kinetic model and comparative batch leaching of major and minor elements from FAP and RE-FAP concentrate. Hydrometallurgy 2019, 184, 218-236 ...
Inadquate stomach acid production may lead to nutritional deficits, belching, heartburn, stomach discomfort and bloating. Your doctor may recommend treatment with a hydrochloric acid or HCl supplement called betaine HCl to increase the amount of acid in your stomach and alleviate hypochlorhydria symptoms.
hydrochloric acid may be used to selectively leach out the calcareous materials from low grade phosphate rock rather than the dissolution of apatite. In this work, the suitability of dilute hydrochloric acid has been studied to leach out the calcareous and dolomitic gangue materials from the indigenous low grade phosphate rock.
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 ...
FIELD: production of pure phosphoric acid and calcium monohydrophosphate. SUBSTANCE: proposed method includes decomposition of phosphate ore by first hydrochloric acid solution at concentration not exceeding 10 mass-%, separation of liquid decomposition product into insoluble solid phase containing admixtures and separate aqueous phase containing phosphate, chloride and calcium ions .
This is particularly true for dicalcium phosphate (DCP), a food additive produced from either sulphuric acid or hydrochloric acid digestion of raw rock material. Get price previous: heavy duty mining equipment next: used mobile gold placer plant
Gastric secretion. The gastric mucosa secretes 1.2 to 1.5 litres of gastric juice per day. Gastric juice renders food particles soluble, initiates digestion (particularly of proteins), and converts the gastric contents to a semiliquid mass called chyme, thus preparing it for further digestion in the small intestine.Gastric juice is a variable mixture of water, hydrochloric acid, electrolytes ...
phosphate rock digestion with hydrochloric acid in panama. This is particularly true for dicalcium phosphate DCP a food additive produced from either sulphuric acid or hydrochloric acid digestion of raw rock material This study determined the natural occurring radionuclide concentrations of 12 DCP samples and 4 tricalcium phosphate TCP samples used for animal and human consumption .
optimal acid-rock ratio conditions (Table-1). The results demonstrate that maximum P2O5 recovery is achieved from an acid-rock ratio of 1:1.2 w/v. The decomposition of phosphate rock with hydrochloric acid is an exothermic process, however, it was observed that temperature does not rise to the limit required for the maximum decomposition of rock
Potentially harmful phosphate-based products derived from the wet acid digestion of phosphate rock represent one of the most serious problems facing the phosphate industry. This is particularly true for dicalcium phosphate (DCP), a food additive produced from either sulphuric acid or hydrochloric acid digestion of raw rock material.
