Add water, shake, filter.

The zinc chloride is very soluble, and will be dissolved in the filtrate, from which the solid can be obtained by evaporation.

The SiO2 will be a residue in the filter paper. Wash it with water, and then evaporate off the water to obtain pure SiO2.

Zinc chloride is water soluble where as silicondioxide is ssand and is insoluble in water. So, add water to the mixture and filter sand is on the filter paper and zinc chloride is in filtrate.
