Pressure leaching of leucoxene concentrate using Ca(OH)2

The results of studying the desiliconization of a leucoxene concentrate using burned lime as a reagent in the presence of NaOH as a catalyst are presented. This process is based on the selective interaction of CaO with the fine silica present in leucoxene grains, which results in the formation of Ca...

Description
Summary:The results of studying the desiliconization of a leucoxene concentrate using burned lime as a reagent in the presence of NaOH as a catalyst are presented. This process is based on the selective interaction of CaO with the fine silica present in leucoxene grains, which results in the formation of CaSiO 3 at high temperatures and pressures (autoclave process). Experiments are performed on the initial leucoxene concentrate and the products of its beneficiation after magnetizing roasting.
