Florida Industrial and Phosphate Research the effect of rock impurities on the phosphoric acid Industrial and Phosphate Research Institute. MODELING OF A WET-PROCESS PHOSPHORIC ACID On Jan 1, 1980 K. Shakourzadeh (and others) published: MODELING OF A WET-PROCESS PHOSPHORIC ACID REACTOR:
This very pure phosphoric acid is obtained by burning elemental phosphorus to produce phosphorus pentoxide and dissolving the product in dilute phosphoric acid. This is the cleanest way of producing phosphoric acid, since most impurities present in the rock have been removed when extracting phosphorus from the rock in a furnace.
Laboratory tests were conducted to study removal of magnesium impurities from western phosphate rock concentrates by selective leaching. The systems evaluated included leaching with dilute sulfuric acid, leachng with ammonium sulfate, and leaching in an aqueous medium with sulfur dioxide gas.
Phosphoric acid is produced from fluorapatite, known as phosphate rock, 3Ca3(PO4)2.CaF2, by the addition of concentrated (93%) sulfuric acid in a series of well-stirred reactors. This results in phosphoric acid and calcium sulfate (gypsum) plus other insoluble impurities.
They are rich in nitrogen but lack phosphorus. Phosphate Rock Impurities thilmany McFadden Colorado State University; Marisa Bunning I.

Find out information about phosphate. salt or ester of phosphoric acid phosphoric acid, . is a compound produced by treating rock phosphate with sulfuric acid or .
Effect of Rock Impurities as Determined from Rock Production Data. 02-146-202Final. Abstract. Over the years, FIPR has spent several hundred thousand dollars on laboratory and pilot plant studies to determine the effect of rock impurities on the phosphoric acid attack tank performance.
1. Phosphoric acid is a clear, colorless, odorless liquid with a syrupy consistency. 2. Phosphoric acid is used as an acidifying agent to give colas their tangy flavor. 3. Due to the use of phosphoric acid, cola is a actually more acidic than lemon juice or vinegar! The vast amount of sugar acts to mask and balance the acidity. 4.

Phosphoric acid is extracted from phosphate rock by a wet process comprising dissolving the phosphate rock which may contain gypsum, metal and fluorine impurities
The wet process involves treatment of the rock phosphate with acid producing phosphoric acid (also called green or black acid) and gypsum which is removed as a by-product. The impurities which give the acid its color have not been a problem in
Florida Industrial and Phosphate Research the effect of rock impurities on the phosphoric acid Industrial and Phosphate Research Institute. MODELING OF A WET-PROCESS PHOSPHORIC ACID On Jan 1, 1980 K. Shakourzadeh (and others) published: MODELING OF A WET-PROCESS PHOSPHORIC ACID REACTOR: INFLUENCE OF PHOSPHATE ROCK IMPURITIES.
The impurities contained in the phosphate rock can have an effect (not always harmful) on downstream production processes and products. For example, impurities have the potential to influence the speed of corrosion-erosion, filtration rate, surface of filtration, as well as the density and viscosity of the phosphoric acid product.
