The Republic of Guinea has the largest bauxite reserves in the world. Therefore, their study represents a special subject. Guinea has seven provinces containing bauxite, but the richest is the Boké region. Of essentially sedimentary and residual origin and of the gibbsite or gibbsite-boehmite type, these bauxites contain on average more than 50% alumina and on average 2% silica.Guinea is today one of the countries that attracts the largest aluminum companies in the world due to its bauxite mining resource, which is the main ore in obtaining alumina.Our major concern as researchers is and…mehr

Produktbeschreibung
The Republic of Guinea has the largest bauxite reserves in the world. Therefore, their study represents a special subject. Guinea has seven provinces containing bauxite, but the richest is the Boké region. Of essentially sedimentary and residual origin and of the gibbsite or gibbsite-boehmite type, these bauxites contain on average more than 50% alumina and on average 2% silica.Guinea is today one of the countries that attracts the largest aluminum companies in the world due to its bauxite mining resource, which is the main ore in obtaining alumina.Our major concern as researchers is and remains the enhancement of these resources to derive more income for the socio-economic development of our nation.In this book, you will find the results of two experiments in the context of the transformation of bauxite into alumina, techniques and methods that we have experimented with to enable companies to valorize standard bauxites from Guinea and others with the same mineralogical characteristics and chemical under low temperature processing conditions. The objective is to enable the transformation of bauxite at a lower cost, which would also facilitate the establishment of factories on site.
