GB2192388A Process for leaching silica sand to reduce

A process for leaching silica sand to reduce the iron content thereof comprises the steps of drying- preheating the sand; vigorously mixing the preheated sand in a suitable intensive mixer, e.g. a rotating pan mixer, with sufficient sulphuric acid (e.g. 7.5 kg 100% H2SO4/tonne sand) to keep the surface of each grain of sand coated with a thin film of sulphuric acid during mixing; and retaining

Enrichment and extraction of lanthanum from Belitung

Jan 01, 2020· In silica sand, the element of lanthanum forms minerals associated with other elements, so further separation is needed to obtain individual lanthanides. Based on this finding, extraction of lanthanum from Belitung silica sand by heap leaching using sulfuric acid and complexation with phytic acid as ligand was studied.

Five efficient methods of removing iron from silica sand

Oct 13, 2019· Iron removal by acid leaching separation is based on the fact that quartz is insoluble in acid (except H, impurity minerals containing Fe can be dissolved by acid solution), so that the purpose of removing iron-bearing minerals from quartz sand can be achieved. The acid leaching method can not only remove iron-bearing minerals from quartz sand, but also remove non-metallic impurity minerals
