Laterite and its potential as an alternative-bauxite

Aluminium-related materials play a significant role in the current industrial applications, including metallurgy, ceramics, medicine, dentistry, automobile, and construction. Al is extracted from bauxite ore which will be extinct sooner than expected as the demand for Al is ever-increasing. Thus, a...
