Iron and Manganese. Iron may exist in water as a ferrous or ferric inorganic salt or as a sequestered organic complex. Ferrous iron exchanges in resin, but ferric iron is insoluble and does not. Ferric iron coats cation resin, preventing exchange. An acid or a strong reducing agent must be used to remove this iron.

Silica (silicon dioxide), in some cases, is an anion.. The chemistry of silica is a complex and somewhat unpredictable subject. In similar fashion as TOC reports the total concentration of organics (as carbon) without detailing what the organic compounds are, silica reports the total concentration of silicon (as silica) without detailing what the silicon compounds are.
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 …
The chemical coagulation method treats White Carbon Black (WCB) wastewater with high cost and low silica removal rate. Meanwhile, aluminum electrode is mostly used in the treatment of SiO 2-containing wastewater by electrocoagulation (EC), however, the price of aluminum is high despite the effective removal.This work is dedicated to the application of …
Silica can be removed from water through ion exchange, lime-soda softening, ultrafiltration, reverse osmosis, distillation and electrocoagulation. For residential use, reverse osmosis and distillation are the best methods for silica removal.
As Ruediger said; you may use Amin collectors such as Armac C or Armac T for reverse flotation of Quartz (if silica (SiO 2) content of your coal sample is due to availability of Quartz).
A novel kind of iron oxide supported on carbon nanotubes (CNTs) was prepared for adsorption of antimony (Sb)(III) in aqueous solution and it has been found that the solution pH values and adsorptive temperatures have no significant influence on Sb(III) removal.
Adsorption of metal ions from low traces and efficient regeneration processes need additional research. ... Holail, H. & Olama, Z. Heavy metals removal using activated carbon, silica and silica ...
Once you have shiny, clean silver keep it that way. Wrap individual silver pieces in cotton or acid-free paper so they don't scratch one another and seal them away from air and moisture in a plastic bag. Before closing the bag, add a piece of chalk or a silica gel packet. Chalk and silica are desiccants. They absorb any moisture already ...

Shown in Fig. 1 is the flow sheet of the complete purification procedure. At first, an acid leaching stage was used to remove small quantities of impurity minerals prior to silica extraction from diatomite. 10 g of raw diatomite sample were leached in 2.2 M HNO 3 acid solution at 60 °C for three-hours under constant stirring. HNO 3 quantity was added gradually …
