Leaching the Unleachable Mineral Rare Earth Dissolution

Monazite is a poorly soluble mineral of rare earth phosphate. It is an ore of the rare earths which is difficult to break down; in industry either concentrated sulphuric acid or caustic soda is used to attack finely ground monazite at between 140 C and 400 C. In these processes, the rare earths are converted into different solid compounds, undergoing an incomplete conversion.
