Por serem minerais levemente soluveis, a dissolucao nao estequiometrica em meio aquoso e um dos principais mecanismos de geracao de cargas em fosfatos. A composicao quimica e a estrutura cristalina determinarao as propriedades interfaciais dos fosfat

As minerações brasileiras têm enfrentado obstáculos em função dos grandes volumes de rejeitos a serem dispostos. Isso resulta do fato dos minérios atualmente processados apresentarem teores cada vez mais baixos, além da carência de tecnologi
