Silica flour is a form of silicon dioxide used in gold smelting. It is also a key ingredient widely used in lead refining mostly at lead automotive battery  refining plants.

 A flux must always be tailored to the sample being run. For a sample that contains a lot of oxidizing agent, a reducing flux, usually silica would need to be used. The reaction for this is as below:

    SiO+  02-      ------>         SiO32-


From this reaction oxides in the sample react with the silica and are reduced to silicates which can be skimmed off from the slag.
