What Is Involved in Phosphate Mining? (with pictures)

Feb 11, 2021 Phosphoric acid is also produced in large quantities and, together with other products of phosphate mining, has many uses in industrial chemistry. After the mining and extraction processes have been completed, the resulting waste products

During 2008, the mine produced . 6.6 Mt of phosphate ore, generating 1.3Mt of phosphoric acid. Annual production records were set for defluorinated phosphate, purified phosphoric acid and ammonium polyphosphate. In 2007, the company initiated a $260m debottlenecking project in order to expand production of phosphoric acid to 180,000t/y.

acid. The phosphoric acid is the main ingredient in fertilizer, but can also be used in animal feed supplements, soda, or soap. Sulfuric acid production creates a lot of heat. This heat is used by a power plant to generate electricity, which helps to power both sulfuric acid production and phosphoric acid

Phosphate Mining Biological Diversity

After beneficiation, the separated phosphate ore is treated with sulfuric acid to produce phosphoric acid, which is used in synthetic fertilizer. The process also creates phosphogypsum, a radioactive byproduct that is stored in mountainous stacks that are hundreds of acres wide and hundreds of feet tall.

The major useful component of phosphate ore is phosphorus in the form of the phosphoric anhydride P 2 O 5. The P 2 O 5 content in phosphate ores varies from 2–6 to 25–34 percent, depending on the processing behavior, mining and geological conditions, and other factors.

Phosphoric acid Wikipedia

Phosphoric acid, also known as orthophosphoric acid or phosphoric(V) acid, is a weak acid with the chemical formula H 3 P O 4.It is normally encountered as a colorless syrup of 85% concentration in water. The pure compound is a colorless solid.. All three hydrogens are acidic to varying degrees and can be lost from the molecule as H + ions ().When all three H + ions are removed, the result is
