Upgraded rock - Ecophos

About

Modular HCl-based process to upgrade your raw material

Prayon has the widest experience available on the market in processing high-impurity phosphate rocks.

Depending on the type and quantity of impurities, traditional phosphoric acid processes can meet the following issues with low-grade rocks :

  • Filtration affected by the high viscosity
  • Formation of gel at the concentration stage
  • Post precipitation and scaling

Therefore, Ecophos as part of Prayon Technologies developed the unique “Ecophos” process to recover P2O5 from low-grade phosphate rocks by adding diluted hydrochloric acid. HCl specific consumption can be reduced by addition of sulfuric acid in a final module to recycle HCl and generate a pure gypsum. This process provides an outstanding raw material for any phosphoric acid plant: the DCP “super-rock”.

Ecophos is a chemical beneficiation process with a recovery efficiency far above any traditional beneficiation plant (up to 90%). It produces a DCP “super-rock” of high quality (up to 41% P₂O₅) leading to the following benefits using it as raw material instead of phosphate rock.

Advantages
What are the benefits of using DCP super-rock upgraded through the Ecophos Process to feed your Phosphoric Acid plant?

Significant increase of capacity for an existing plant

Up to 200% of the initial capacity

High-quality acid product

High P₂O₅, low MER, low solids, and low heavy metals content
