Problems in the dissolution of silicates by acid mixtures

Celia Maqueda,   José Luis Pérez Rodríguez  and  Angel Justo  

Abstract

The decomposition of silicate rocks using mixtures of mineral acids has been studied. The conventional acid method of dissolving rocks with hydrofluoric-perchloric-nitric acid mixtures is unsatisfactory when pyrophyllite is present. This mineral is not destroyed by acid attack, whereas other silicates such as mica, kaolinite, quartz, feldspars, smectite and interstratified illite-smectite are decomposed. If the acid attack is carried out in a pressure vessel, pyrophyllite is dissolved completely, but with more difficulty than the other silicate minerals present.
