Abstract
El caolín es un silicato de aluminio hidratado Al2 Si2O5(OH)4, producto de la descomposición de rocas feldespáticas principalmente. El término caolín se refiere a arcillas en las que predomina el mineral caolinita; su peso específico es de 2.6; su dureza es 2; de color blanco, puede tener diversos colores debido a las impurezas; brillo generalmente terroso mate; es higroscópico (absorbe agua); su plasticidad es de baja a moderada. El yacimiento de Caolín sirve académicamente a la Carrera de Ingeniería de Minas para realizar prácticas de docentes y estudiantes en Perforación y voladura, topografía, mecánica de rocas y diseño de explotación a Cielo Abierto. El objetivo del presente trabajo de investigación se circunscribe a demostrar que la explotación del yacimiento de caolín a cargo de la Carrera de Ingeniería de Minas, Petróleos y Geotécnia es técnicamente factible y económicamente rentable. El estudio permitió determinar que el yacimiento cuenta con 318.892,14 toneladas de Caolín, el cual será comercializado a un precio en una primera Fase de 20,00 $us/Tonelada y a un ritmo de explotación de 12,00 Ton/día; en una segunda Fase, se implementará un proceso de tratamiento que permitirá obtener un producto de mayor calidad que podrá comercializarse a un precio de 100,00 U$us/Tonelada y a un ritmo de explotación de 40,00 Ton/día. Además, desde el punto de vista económico, el estudio permitió determinar que la utilidad por año será en la primera Fase de 53.886,17 US$ y en la segunda Fase de 1.03.732,20 US$. La factibilidad del proyecto está demostrada puesto que el estudio arrojó una razón de Beneficio/Costo de 4,1 en la primera fase y de 21.62 en la segunda fase.
Kaolin is a hydrated aluminum silicate Si2O5 Al2 (OH) 4, product of the decomposition of feldspathic rocks mainly. The term refers to kaolin clays in predominantly mineral kaolinite; its specific gravity is 2.6; its hardness is 2; white, you may have different colors due to impurities; generally earthy matt gloss; is hygroscopic (absorbs water); its plasticity is low to moderate. The site serves academically Kaolin Race Mining Engineering practices for teachers and students in Drilling and blasting, topography, rock mechanics and design Opencast. The objective of this research is confined to demonstrate that the exploitation of the deposit of kaolin in charge of the School of Mining Engineering, Petroleum and Geotechnical is technically feasible and economically profitable. The study allowed us to determine that the site has tons of Kaolin 318,892.14, which will be marketed at a price in a first phase US $ 20.00 / ton and operating at a rate of 12.00 tons / day; In a second phase, a treatment process which will obtain a higher quality product that can be marketed at a price of 100.00 U $ us / Tonne and operating at a rate of 40.00 tons / day will be implemented. Moreover, from the economic point of view, the study allowed us to determine that the income per year will be in the first phase of US $ 53,886.17 and the second phase 1.03.732,20 US $. Project feasibility is demonstrated since the study showed aratio ofbenefit/costof 4.1 in the first round and 21.62 inthe second phase.
