El caso de Morro Puto, Municipio de Nechí, Antioquia desde 2019 hasta 2021(Universidad EAFIT, 2021) Pasqualotto Jiménez, Alejandra; Restrepo Rodríguez, Juan Pablo; Montoya Brand, Mario AlbertoÍtem Caracterización sociodemográfica, motivacional y de satisfacción en los mineros de alto y bajo rendimiento de la mina la Margarita, Titiribí (Antioquia) : una prueba piloto(Universidad EAFIT, 2023) Jiménez Arismendy, Fabio; López Gallego, Francisco DaríoObjective:To describe the socio-demographic, motivational, and satisfaction level characteristics of high and low-performance subway miners at the La Margarita mine, to have information in a pilot test that allows implementing strategies for improvement of the stakeholders. Method: a descriptive study, using the work motivation questionnaire "CMT" and a job satisfaction questionnaire, was applied to 12 subway mining workers currently working at the La Margarita mine. Results: the total population evaluated was men, 83.33 % of whom were over 40 years old, three participants in the study were over 50 years old, and two participants belonged to the group of low-performance miners; the degree of schooling was lower in most low-performance miners. It was found that the primary motivating factor is salary, followed by recognition for high-performance miners and affiliation for low-performance miners. Similarly, a high level of job satisfaction was reported, with a satisfaction percentage of 92.56 % Conclusion: Differences were found, in the intrinsic motivational profile, in preferred means of obtaining rewards at work, and in the external motivational factor of greater and lesser relevance for high and low-performance miners.Ítem Contribución a la caracterización estructural y geoquímica de las mineralizaciones de hierro en el sector El Palmor, Magdalena(Universidad EAFIT, 2021) Castro Burgos, Juan Camilo; Coronado Patiño, Andy; Beltrán Triviño, Alejandro IvánIn the village of El Palmor (Ciénaga, Magdalena), there are important manifestations of iron presented with form of alluvial deposits and tabulate bodies on the Anortositas unit of the Sevilla river, which have not yet defined the existence of a possible structural control on the seams, neither a chemical classification of mineralizations. Four samples of iron were taken, join with structural information of the zone; the main purpose was identified mineral’s presents, iron’s concentration percentage, and to identify the origin of these deposits, off course whether there is any structural implication on the location of the mineralized bodies. The samples were characterized by two laboratory tests (1) X-ray diffraction analysis (XRD) to corroborate the existence of kaolinite / dikite, magnetite, hematite and goethite and (2) X-ray fluorescence (XRF) for show Fe2O3 concentrations of approximately 17%. Therefore, it was inferred that iron declarations were associated with the formation of anortositic rocks, which by fractional crystallization of immiscible fluids rich in Fe and Ti are trapped between the crystalline mesh, which in turn they are accumulated by the phenomenon of filter pressing and subsequently mobilized to areas of low pressure, in this case possibly to the Sevilla guideline.Ítem Diseño de un manual de geo-metalurgia como herramienta para los procesos de enseñanza-aprendizaje en los procesos extractivos del cobre(Universidad Eafit, 2020) Zuluaga Zapata, Karen Johana; Marín Cerón, Maria Isabel; Garrido Palma, Mauricio NicolásÍtem Efectos de la devaluación del peso colombiano sobre la actividad del sector minero en Colombia(Universidad EAFIT, 2022) Lasso Orjuela, Diego Andrés; Vergara Garavito, Judith CeciliaOne of the most important pillars of the Colombian economy is mining, which contributes greatly to the generation of value, which is then reflected in investment, sources of employment, and development. Unfortunately, a global economy is positively affected by economic events worldwide, which is quickly evident in the behavior of the local currency, also becoming the main indicator in business decision-making. In such a way it is essential what are the effects of the devaluation of the Colombian peso against the income generated by mining in Colombia. Through an analysis of such variables, it is intended to propose a mathematical model that manages to define if they have any relationship and if there is, what are their most important characteristics.Ítem Estudio de prefactibilidad para la creación de una refinería de oro en Antioquia(Universidad EAFIT, 2023) Gallego Giraldo, Juan Felipe; Uribe de Correa, Beatriz Amparo; Velásquez Peláez, SebastiánThe "Feasibility Study for the Creation of a Gold Refinery in Antioquia" is a report that analyzes the feasibility of building a gold refinery in the Antioquia region of Colombia. The study is divided into several sections that address different aspects, such as market analysis, technical feasibility, financial analysis, and environmental impact. In the market analysis, the demand for gold and supply in the international and national markets is examined. The competition in the sector is also studied, and the main potential customers are identified. Regarding technical feasibility, the availability of raw materials and the processes necessary for gold refining are analyzed. Available technologies are studied, and an assessment of construction and operation costs is made. In the financial analysis, an investment study is conducted, and the profitability of the project is evaluated. Projected revenues and costs are examined, and the investment payback period is calculated. Finally, in the environmental impact analysis, possible environmental impacts are evaluated, and measures are proposed to mitigate them. In conclusion, the study concludes that the construction of a gold refinery in Antioquia is viable and profitable and has the potential to generate significant economic benefits for the region.Ítem Estudio de prefactibilidad para un proyecto de servicios de soporte a la operación con equipos menores a una empresa minera(Universidad Eafit, 2020) Mejía Escobar, David; Gómez Salazar, Elkin ArcesioÍtem Función del área de gestión humana en el proceso de adaptación ante los cambios organizacionales derivados de la pandemia percibida por un grupo de trabajadores del sector minero en Colombia(Universidad EAFIT, 2021) Martínez Soto, Miguel Leonardo; Santos Ávila, Víctor Hugo; Betancur Hurtado, Carlos MarioObjective. Analyze the role of the human management area in the process of adaptation to the organizational changes derived from the Covid-19 pandemic perceived by a group of workers in the mining sector in Colombia. Method. A qualitative descriptive cross-sectional study was carried out; The research design was a case study based on semi-structured interviews with ten (10) employees with a minimum of two (2) years of service. Outcome. The data obtained allowed us to understand the human management function in the employee adaptation process, its fundamental contribution to facilitate the implementation of strategies, measures and actions aimed at mitigating this unexpected impact of Covid-19 in mining companies in Colombia. It is shown that human management as a strategic partner helped the compliance and implementation of corporate measures in employees. Conclusion. It was evidenced that not only the countries were not prepared for this pandemic, the organizations were not oblivious to this impact, and the mining companies who maintain a system of security controls in place in order to have the operational dynamics of their processes, although the employees They perceive that human management was important in the adaptation process, employees have noticed the decrease in human management leadership once the implementation stage has been reached, they are manifesting that they feel alone in the final part if it could be said of the adaptation process in the face of changes organizational problems caused by the Covid-19 pandemic.Ítem Guía para entidades financieras que permita el conocimiento de la operación y análisis financiero de clientes mineros(Universidad EAFIT, 2022) Rodríguez Acevedo, Stephanny; Salazar Castro, Daniel Orlando; Ochoa Bedoya, Daniel; Sánchez Moreno, Andrei; Durango Gutiérrez, Maria PatriciaÍtem Implementación piloto de un Sistema de Administración de Riesgos Operativos SARO, en el proceso financiero de una comercializadora internacional de oro(Universidad EAFIT, 2021) Burbano Daza, Diana Lizeth; Duque Cano, Dairon Rodrigo; Rojas Ormaza, Brayan RicardoMining has been one of the economic activities most exposed to risks within the economy of a country, due to the great complexity of the development of its processes; this is why international gold trading companies are directly linked to certain risks of this economic activity. With the foregoing, the need arises to identify and quantify the existing operational risks, and through controls, analysis and monitoring, minimize the impacts that directly affect the reason for being of the organization. In this work, emphasis will be placed on the operational risks of the company's financial process, based on the guidelines of ISO 31000, taking into account that there is no specific risk regulation for the company's sector, and in this way propose an Operational Risk Management System, which enables the identified risks to be managed.Ítem Minería mecanizada en el Departamento del Chocó : ¿fuente de crecimiento económico y bienestar?(Universidad EAFIT, 2022) Albornoz Torres, Sandra Vanessa; Cújar Couttin, Darío; Muñoz Mora, Juan CarlosThis article takes a descriptive approach to the relationship between the increase in mechanized gold mining and the evolution of economic growth and social welfare in the department of Chocó. The consolidation of gold production in the region has generated extra income to the municipalities through the General Royalties System (SGR), which increases the funds available for social investment and growth. To verify this intuition, the paper uses descriptive statistics to analyze trends in mining production in Chocó and the various social investment projects financed with royalty revenues. In addition, information is presented on the behavior of socioeconomic indicators related to education, health, employment and poverty, with the purpose of observing whether the social investment from royalty revenues is reflected in the variation of the behavior of these variables. The descriptive analysis shows that despite the increase in production and SGR revenues in Chocó, the results in education, employment and poverty do not show a significant improvement. However, despite this, the contribution from royalties is not considered ineffective, because the behavior of these indicators is linked to structural problems of the different governmental entities that make up the department, which is beyond the scope of this work.Ítem Modelo geológico-estructural de la mineralización vetiforme en la mina El Gran Porvenir del Líbano, usando Leapfrog Geo(Universidad EAFIT, 2021) Duque Alzate, Daniel Esteban; Beltrán Triviño, Alejandro IvánÍtem Modelo para evaluar las variables operativas, niveles de inversión y variables para la venta en Minera El Roble(Universidad EAFIT, 2023) Feria Fortich, Fernán Esteban; Escalante Gómez, Juan EstebanÍtem Plan de negocios para Carbomax de Colombia S.A.S de un fondo privado de inversión para el sector minero, a través de garantías en recursos y reservas mineras(Universidad EAFIT, 2021) Sandoval Salazar, Darío Alexis; Rodríguez Monsalve, Lilian Paola; dirfinanciera@aym.com.co; buribe@eafit.edu.coÍtem La responsabilidad extracontractual del Estado por el daño ambiental derivado del uso del mercurio en la minería de oro en Colombia : agua, precaución ambiental y desarrollo sostenible(Universidad EAFIT, 2020) Zapata Jaramillo, Laura; Vásquez Vera, Juan EstebanÍtem Ruptura del contrato psicológico relacional entre las diferentes generaciones en una empresa del sector minero(Universidad EAFIT, 2023) Bedoya Agudelo, Paola; Collazos Pantoja, Danna Valentina; Román Calderón, Juan PabloÍtem Sembrar cultura, recoger legalidad: comportamiento, vida cotidiana y acción colectiva(Universidad EAFIT, 2021) Eslava Gómez, Adolfo; Silva Jaramillo, Santiago; Valencia Vélez, Sergio Andrés; García-Luna, Estefanía; Peralta Vélez, Ana María; Echavarría Areiza, Andrea; Londoño Quiceno, Yeison Darío; aeslava@eafit.edu.co
