To remove FeO (basic) an acidic flux silica is added during smelting FeO then combines with to form ferrous silicate slag which floats over molten matte and hence can be easily removed DNA separation by silica adsorption

This article includes a list of general references, but it remains largely unverified because it lacks sufficient corresponding inline citations Please help to improve this article by introducing more precise citations DNA separation by silica adsorption is a method of DNA separation that is based on DNA molecules binding to silica surfaces in the presence of certain salts and under certain.
