Evaluation of two processes for the production of phosphoric acid in pilot scale

Creators

Description

Two processes for the production of phosphoric acid, based on dihydrate route and hemihydrate route, have been evaluated. The processes were tested in a pilot plant using the concentrate obtained from phosphorus-uraniferous mineral from Itataia mines (CE, Brazil). Results were evaluated from the data obtained from phosphorus and uranium solubilizations. Also presented, although in a summarised way, are the description of the construction of the pilot plants and the analytical methods for the follow-up of processes. (Author)

Abstract (Portuguese)

E feita uma avaliacao de dois processos para producao de acido fosforico via umida: segundo a rota dihidrato e segundo a rota hemidihidrato. Estes processos foram testados em escala piloto utilizando concentrado obtido a partir do minerio fosforo-uranifero da jazida de Itataia (CE, Brasil). Os resultados foram avaliados com base nos valores das solubilizacoes de fosforo e uranio. Sao tambem apresentadas, de forma sumaria, as descricoes das montagens das unidades piloto e a metodologia analitica de acompanhamento dos processos. (Autor)
