In this case, the preliminary enrichment of petalite ore is not required. Given the high content of SiO 2 in the ore, it is impossible to use the traditional Bayer method for this ore processing (Power and Loh, 2010), since it involves the use of high-quality limestone, low silica content and Li 2 O content >5%.

Limestone can also be chemical in origin as is the case with travertine. Chemical limestone forms when calcium and carbonate ions suspended in water chemically bond and precipitate from their aquatic sources. Because of its high calcium content, limestone is usually light in color, although many variations exist.
