Overview

Phosphate Rock an overview | ScienceDirect Topics

The phosphate rock is initially converted to phosphoric acid (P2 O 5) by reaction with sulfuric acid. The phosphoric acid is further processed to produce fertilizers, food-grade and feed-grade additives, and detergents.

Mining and Phosphate Rock Processing Industrial Wastes

The manufacture of phosphorus-derived chemicals is almost entirely based on the production of elemental phosphorus from mined phosphate rock. Ferrophosphorus, widely used in the metallurgical industries, is a direct byproduct of the phosphorus production process.

Phosphates, Industrial Chemical Economics Handbook

In China, where most capacity is based on the thermal acid process, higher energy costs have had an impact on the price of exports. During 2000–15, phosphoric acid exports increased at an average annual rate of 10.8%. A decrease in exports is expected during 2015–20, unless additional investments in wet-process acid capacity are made. Ma’aden Phosphate Company’s expansion in Saudi

Chemical Beneficiation of Phosphate Rock | E & MJ

Figure 1—Typical phosphate losses in Florida. Great effort is spent by the phosphate industry to beneficiate the rock to obtain a concentrate containing 30%-31% P 2 O 5.[1] During this process, much of the phosphate values are lost to the tailings stream.

Sulfuric Acid in the Phosphate Fertilizer Industry

Sulfuric acid is used as a key first step in the production of both MAP and DAP, after which it is mixed with phosphate rock to produce phosphoric acid. And since the phosphoric acid production process consumes energy, an on-site sulfuric acid plant – a net producer of energy – is a critical part of the fertilizer production process.

Phosphoric acid Essential Chemical Industry

Phosphoric acid is produced from fluorapatite, known as phosphate rock, 3Ca 3 (PO 4) 2.CaF 2, 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.

Phosphorite Wikipedia

For use in the chemical fertilizer industry, beneficiated rock phosphate must be concentrated to levels of at least 28% phosphorus pentoxide (P 2 O 5), although most marketed grades of phosphate rock are 30% or more. It must also have reasonable amounts of calcium carbonate (5%), and <4% combined iron and aluminium oxides.

PRODUCTION OF PHOSPHORIC ACID Product Stewardship

The basic chemistry of the wet process is exceedingly simple. The tricalcium phosphate in the phosphate rock is converted by reaction with concentrated sulphuric acid into phos- phoric acid and the insoluble salt calcium sulphate. Ca3(PO4)2+ 3H2SO42H3PO4+ 3CaSO4

Some phosphate rock is used to make calcium phosphate nutritional supplements for animals. Pure phosphorus is used to make chemicals for use in industry. The most important use of phosphate rock, though, is in the production of phosphate fertilizers for agriculture. Virtually all common fertilizers have an “N-P-K” rating. Phosphorus is the “P” in fertilizers. Phosphorus is involved in

In the dry process, rock phosphate is treated in an electric furnace. This treatment produces a very pure and more expensive phosphoric acid (frequently called white acid or furnace acid) used primarily in the food and chemical industry. The cost of converting rock phosphate to the individual phosphate fertilizers varies with the process used. More importantly, the processes used have no

The fertilizer industry often uses the more generic term phosphate. In \൦act, one of the online dictionary definitions for phosphate is “a phosphatic material used for fertilizers

Use of phosphate rocks for sustainable agriculture

Use of phosphate rocks in industry and agriculture. Phosphate rock denotes the product obtained from the mining and subsequent metallurgical processing of P-bearing ores. In addition to the main phosphate-bearing mineral, PR deposits also contain accessory or gangue minerals and impurities. Although considerable amounts of accessory minerals and impurities are removed during
