Chemical Reaction Process Limestone Powder In India

Minor chemical components of limestone include clay, feldspar, pyrite and quartz. Feldspar crystallizes from magma, thus is more commonly found in volcanic rocks. Feldspar is widely used in the ceramic, adhesive and glass industries. Limestone containing pyrite is rare, but has been found Padappakara, India.
