Processes

EcoPhos Modular Range of Phosphate Processes:

EcoPhos has developed a range of process modules that can be combined to create a new innovative phosphate process, dependant on the preference of the client, site conditions, market requirements and raw materials availability.

processes for making feed-grade phosphate directly from phosphate rock

e.g. Module 1; a dilute HCl phosphate rock attack process for DCP
info … Decaphos Bulgaria applies EcoPhos technology …
e.g. module 14; a phosphate rock attack process for making DCP and a "Clean Gypsum" by-product
info … UCCI-Syria builds a plant based on EcoPhos technology …
e.g. Module 13; a phosphate rock attack process making purified phosphoric acid and a "Clean Gypsum" by-product

new innovative processes for making STPP from phosphate rock
PhosX - a new route for purification of WPPA, where P₂O₅ is removed from the liquor rather then removing the impurities
ChemBe-a new process route for chemical beneficiation of low grade rock

Advantages of EcoPhos Rock Attack:

Environmental: low solid waste, no gypsum or clean gypsum by product
Economic: significantly lower investment, competitive production cost
Phosphate salts and upgraded phosphoric acid end-products
Wide range of rock quality acceptable and less pretreatment required
Way of upgrading low-grade ores
Means for valorization of waste HCl streams

EcoPhos WPPA Purification Processes

Ecophos has developed new and innovative processes for the purification of WPPA where P₂O₅ is removed from the liquor, rather than removing the impurities. The recovered P₂O₅ is converted into phosphate salts or phosphoric acid
