in the bauxite industry exploration, beneficiation and refining two main chemical parameters are used for quality control available alumina (aval 2 o 3) and reactive silica (rxsio 2) content.both are determined using a wet chemistry procedure that,soil quality of bauxite mining areas nasaads,the study on soil quality index (sqi) aims to assess the current state of the soil after use and estimating its recovery through sustainable management practices this type of study is being used in this work in order to check the efficiency of forest recovery techniques in areas that have been deeply degraded by bauxite mining process, and compare them with the area of native
