Research Paper (postgraduate) from the year 2007 in the subject Geography / Earth Science - Geology, Mineralogy, Soil Science, grade: A, Abubakar Tafawa Balewa University, course: Applied Geology - Economic Geology/ Mineral Exploration, language: English, abstract: Barite (BaSO4) mineralization occurs within Pan African fracture systems in the Gombe inlier. Gombe Inlier is a Basement dome within the Gongola Basin (Upper Benue trough in Nigeria) which exposes most of the stratigraphic sequence (Bima Sandstone, Yolde Formation, Pindiga Formation and Gombe Sandstone). Fieldwork was conducted from March 23rd – 29th 2007, 20 minerals and rock samples were taken from the veins and host rocks, and then Geochemical, petrographic and structural analysis were conducted to ascertain the quality of barite, associated minerals, nature of host rock and also the type of chemical as well as structural barriers for the mineralization. The results shows that the principal planar planes hosting mineralizations were found to trend mostly in NE – WSW direction which conforms well in smaller scale with the trend of strike slip faults that faulted the inlier and on a larger scale conforms with the general trend of the Benue trough. The fractures are therefore probably subordinate to the general structural trend of the Benue trough. The main associated mineralization was inferred to be anhydrite (CaSO4) which is also a sulphate like barite. This suggest competition for SO32+ by Ba2+ and Ca2+ but the deeper fractures host barite because Ba2+ originate from mantle and brought up by hydrothermal fluid through fractures while Ca2+ could be a dissolved ion in sea water. The quality of the barite in some veins is well over 70% BaSO4 which is economically viable. Part of barite in some veins were leached and recrystallized into spindle crystals by later hydrothermal fluid with little effect on its chemistry. The petrographic studies also revealed the purity of some barite veins and also indicated the presence of other associated minerals and also indicates the nature of the silica chemical barrier for the sulphate mineralizations.

Durante los últimos años, la investigación y el desarrollo de tecnologías para la reducción de las emisiones de gases de efecto invernadero (GEI) en nuestro planeta ha incrementado. Varias soluciones se han propuesto, incluyendo la captura y secuestro de carbono (CCS en inglés). La aplicación de CCS se ha focalizado en las tecnologías de producción de energía a gran escala que utilizan combustibles fósiles. Recientemente, se ha trabajado en el uso de CCS en tecnologías de enriquecimiento de biogás. Esta práctica consiste en la eliminación del CO2 del biogás emitido por digestores anaeróbicos y vertederos con el fin de incrementar la concentración de CH4 en el biogás, generando así un potencial sustituto de gas natural. Dos innovadoras tecnologías en desarrollo almacén además el CO2 eliminado en una forma sólida, a través de un proceso llamado mineralización de carbono. Este proceso utiliza óxido cálcico de los residuos industriales para fijar el CO2 en forma de carbonato cálcico. Idealmente estas tecnologías innovadoras de enriquecimiento deberían mostrar mayores beneficios ambientales en comparación con las tecnologías convencionales ya que almacenan inmediatamente el CO2. La primera tecnología analizada es la regeneración de alcalino (AwR) que consiste en el uso de una solución alcalina para eliminar el CO2 y que es regenerada mediante su exposición a un residuo industrial rico en CaO. La segunda tecnología es enriquecimiento de biogás con cenizas (BABIU), basada en la interacción directa del biogás con las cenizas resultantes de incineradores de residuos municipales. Esta tesis pretende determinar si estas tecnologías innovadoras muestran beneficios ambientales respecto a las tecnologías convencionales de enriquecimiento de biogás, mediante la aplicación de herramientas de la ecología industrial. El análisis de ciclo de vida, el análisis de flujos materiales y el análisis de exergía son aplicadas para el análisis ambiental y de recursos. Asimismo, la viabilidad a largo plazo de las tecnologías es examinada desde el punto de vista económico y material. En general, los resultados indican que las tecnologías innovadoras no muestran un perfil ambiental notablemente mejor que las convencionales, especialmente para AwR donde el uso de la solución alcalina da lugar a un elevado impacto ambiental. Aún así, ambas tecnologías consiguen un significante ahorro de CO2 respecto a las tecnologías convencionales. Asimismo, dado que las dos tecnologías analizadas se encuentran en un período de prueba piloto, se identifican las potenciales mejoras para optimizar el perfil ambiental y económico, como incrementar la eficiencia de la regeneración de la solución alcalina en la tecnología AwR. El análisis económico realizado para AwR resaltó que reducir sus costes operacionales incrementaría la oportunidad de su implementación como negocio. Los resultados pueden ser usados tanto por promotores de estas innovadoras tecnologías para mejorar su viabilidad económica y ambiental a largo plazo, como por promotores y fabricantes de tecnologías similares, como aplicaciones de CCS o enriquecimiento de biogás.

This book focuses on an important technology for mineralizing and utilizing CO2 instead of releasing it into the atmosphere. CO2 mineralization and utilization demonstrated in the waste-to-resource supply chain can “reduce carbon dependency, promote resource and energy efficiency, and lessen environmental quality degradation,” thereby reducing environmental risks and increasing economic benefits towards Sustainable Development Goals (SDG). In this book, comprehensive information on CO2 mineralization and utilization via accelerated carbonation technology from theoretical and practical considerations was presented in 20 Chapters. It first introduces the concept of the carbon cycle from the thermodynamic point of view and then discusses principles and applications regarding environmental impact assessment of carbon capture, storage and utilization technologies. After that, it describes the theoretical and practical considerations for “Accelerated Carbonation (Mineralization)” including analytical methods, and systematically presents the carbonation mechanism and modeling (process chemistry, reaction kinetics and mass transfer) and system analysis (design and analysis of experiments, life cycle assessment and cost benefit analysis). It then provides physico-chemical properties of different types of feedstock for CO2 mineralization and then explores the valorization of carbonated products as green materials. Lastly, an integral approach for waste treatment and resource recovery is introduced, and the carbonation system is critically assessed and optimized based on engineering, environmental, and economic (3E) analysis. The book is a valuable resource for readers who take scientific and practical interests in the current and future Accelerated Carbonation Technology for CO2 Mineralization and Utilization.

The extraordinary growth of the computer and semiconductor industries and the increasing consumption of indium in these technologies in recent years have placed major constraints on current and future reserves of this metal. In the past, geoscientists have noticed the occurrence of indium in a large variety of ore de posits and detailed geochemical and mineralogical work is available for a few ex amples. However, despite the current technological interest, there is no compre hensive textbook that deals with all aspects of indium mineralization and economics. The present study attempts to develop a general metallogenic concept for indium in identifying the essential enrichment processes and their economic significance. The study 'Indium Geology, Mineralogy, and Economics' was commissioned and funded by the German Federal Institute for Geosciences and Natural Re sources (BGR Hannover) and is a contribution to the research program 'BGR 2000 - Raw Materials with Short Lifetime Reserves'. This program focuses on raw materials with known reserves confined to the next 20-25 years at static de mand. The future availability of reserves is usually estimated by dividing the known reserves by the current annual consumption. In fact, lifetimes of reserves are inappropriate measures because they depend on many parameters and there fore represent a "snapshot" of a dynamic system. In order to provide a sustainable use of raw materials with short lifetime reserves, a significantly higher amount of innovation is needed compared to raw materials with long lifetime reserves.
