Resumen
Este proyecto de tesis analiza el mercado minero de las tierras raras con el fin de identificar una oportunidad de negocio para Chile frente a la creciente dinámica mundial de demanda por estos elementos minerales en las innovadoras tecnologías digitales actuales. El territorio nacional cuenta con depósitos de arcillas y de relaves que contienen los elementos de: Lantano (La), Cerio (Ce), Praseodimio (Pr), Neodimio (Nd), Samario (Sm), Europio (Eu), Gadolinio (Gd), Terbio (Tb), Disprosio (Dy), Holmio (Ho), Erbio (Er), Tulio (Tm), Iterbio (Yb) y Lutecio (Lu), apreciados en su valor económico.
El análisis realizado responderá a la problemática de utilización de las arcillas (un material indeseable en la minería) que tendrían un interesante valor económico por su contenido de Tierras Raras. De los relaves, residuos que se generan de la molienda y flotación minera, es viable recuperar tierras raras igualmente valiosos para las tecnologías imperantes en el mundo digital, convirtiéndose estos residuos en recursos -economía circular - al procesarlos usando tecnologías extractivas que seleccionen estos elementos de valor para ser comercializados en el mercado internacional.
Esta tesis postulará las mejores vías para crear un proyecto de negocios extrayendo sustentablemente las tierras raras desde las arcillas y los relaves que diversifiquen la oferta de productos mineros de Chile, favorezcan a la sociedad con empleabilidad y a los empresarios que decidan invertir en este desafiante y connotado rubro con buenas perspectivas de éxito.
This thesis project analyzes the rare earth mining market in order to identify a business opportunity for Chile in light of the growing global demand for these mineral elements in today's innovative digital technologies. The national territory has clay and tailings deposits that contain the elements of: Lanthanum (La), Cerium (Ce), Praseodymium (Pr), Neodymium (Nd), Samarium (Sm), Europium (Eu), Gadolinium (Gd), Terbium (Tb), Dysprosium (Dy), Holmium (Ho), Erbium (Er), Thulium (Tm), Ytterbium (Yb) and Lutetium (Lu), appreciated in their economic value. The analysis carried out will respond to the problem of using clays (an undesirable material in mining) which would have an interesting economic value due to its Rare Earth content. From tailings, residues that are generated from milling and mining flotation, it is feasible to recover rare earths equally valuable for the prevailing technologies in the digital world, turning these residues into resources - circular economy - by processing them using extractive technologies that select these elements from value to be commercialized in the international market. This thesis will postulate the best ways to create a business project sustainably extracting rare earths from clays and tailings that diversify the offer of Chilean mining products, favor society with employability and entrepreneurs who decide to invest in this challenging and notorious business with good prospects for success
