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 ...

If the silica is reactive silica, then Reverse Osmosis is the most practical method to remove it from the water supply. Reverse osmosis will reduce both colloidal and reactive silica, but proper pretreatment is necessary, including oxidation of iron, sulfur, and manganese, removal of chlorine, and chloramine, while hardness must be treated with ...
