To recover potassium from feldspar, a biowaste, i.e., eggshell, was used. The chief composition of eggshells is calcite. As it is a rich source of Ca, hence it is used with HCl to produce calcium chloride. Feldspar is an aluminosilicate mineral that

La, Ce and Tb were leached from a residue generated by lixiviating phosphor with 3.3 N H2SO4. Model equations to predict leaching extent of La, Ce and Tb were generated by factorial designing. At the same strength, HCl could leach more La, Ce and Tb

This work focuses on extraction of potassium from feldspar through pyro-hydrometallurgical route. Calcium chloride was used as roasting agent for feldspar. Effect of various operating variables, viz. time, roasting temperature and CaCl2 dose on exten

An integrated approach has been made to extract potassium and aluminium from a silicate mineral, i.e. nepheline syenite with 5.4% K2O, 19.9% Al2O3, 55.5% SiO2. Chloridising-roasting experiments were carried using CaCl2 at 900 °C for 1 h and water le
