Abstract. Mining causes soil damage and destruction. In the process of removing the desired mineral material, original soils become lost, or buried by wastes. In many countries legislation now requires that surface soils be conserved and replaced, but there is a vast heritage of degraded land left by past mining that requires restoration.
Details1. Introduction. Kaolin is a white-brown powdery clay mineral. It has the main constituent of kaolinite of a hydrous aluminum silicate (Al 2 O 3.2SiO 2.2H 2 O) with a single tetrahedral silicate layer linked via oxygen molecules to a single alumina octahedral layer. The most common auxiliary minerals found with kaolin are maternal rocks such as mica, …
