Alunite is generally blocky or earthy. Its crystal is not obvious and it is a cryptocrystalline mineral. If the purity should be white, but contains impurities after the light gray, light red, light yellow or reddish-brown, glass luster, bottom cleavage moderate.

Alunite can be used in manufacturing, chemical industry, food industry, agriculture, chemical industry, and environmental sanitation industries. It is used in printing, paper making, tanning, painting, and other industries. It is also used as a mordant for dyeing cloths, as well as for ramming and filming. Hardeners, catalysts for ammonia synthesis, clarifiers for sugar and water, precipitants for beneficiation etc.
