Bauxite Mining Industry in Guinea and the Valorization Prospects of the Resulting Residue for Engineering Purposes | Chapter 8 | Novel Perspectives of Engineering Research Vol. 4

 Because of the importance and diversity of its natural riches, Guinea is recognised as a geological disaster. Experts, regardless of the grading system, utilise superlatives to highlight the country's tremendous potential. Guinea has 33 percent of the world's known bauxite reserves, according to several geological surveys. The way a deposit's content is defined is inconsistent, and the ideas and definitions are muddled up in different statistics data. As a result, when evaluating distinct bauxite resources, an expert must be aware of the terminologies in use and change his evaluation accordingly. The large bauxite potential presents a significant chance for the country to become a global leader in the bauxite and aluminium industries, as well as create red mud value-adding prospects. The bauxite potential and local alumina industry in Guinea, as well as the technology utilised to evaluate the resulting red mud, are discussed in this article. Guinea's largest direct contribution to GDP comes from the bauxite and alumina sector.

Research on Ecological and Botanical Diversity in Haloxylon Persicum Community at Al-Qassim Region in Kingdom of Saudi Arabia | Chapter 6 | Challenging Issues on Environment and Earth Science Vol. 9

 In the desert, Haloxylon persicum is a significant species. It not only aids in the stabilisation of sand dunes, but it also aids in the conservation of soil and water, as well as the slowing of desertification. The fact that the plant species is endangered, on the other hand, has far-reaching consequences. Drought-tolerant Haloxylon persicum is indigenous to northwest China, Russia, and the Middle East. The study's research areas were chosen based on how well they represented the ecological and botanical diversity of the H. persicum species in Saudi Arabia's Al-Qassim region. The researcher found nine sites in the three areas. The researcher calculated vegetative parameters such as species coverage, density, and frequency. In addition, soil testing was done in each of the three research areas. To determine the soil types, the electrical conductivity (EC) Mmoh / cm, pH, total dissolved salts (TDS) as parts per million (ppm), Sodium Ions, Potassium, and soil texture were all measured. Beginning with seedling emergence and establishment, soil variables have a significant impact on the survival and dispersion of H. persicum species, according to the findings. The researcher suggests that the plants be stopped from being overgrazed and used as the principal source of wood for charcoal to safeguard the H. persicum ecosystem. Because of its importance to the desert topography, the Kingdom of Saudi Arabia and other countries where H. persicum is found must safeguard the species.
