Resumen
El siguiente trabajo consiste en el desarrollo de un modelo geometalúrgico para un depósito de arcillas iónicas ubicado en Penco, Región del Biobío, propiedad de la empresa Biolantánidos (REE Uno Spa). La realización de este modelo consiste primero en la generación de una tabla de clasificación geometalúrgica con todos los parámetros que se tenían identificados previamente al desarrollo de este trabajo. La tabla de clasificación geometalúrgica de bloques (CGMB de Yamal) es una tabla similar a la tabla de clasificación geomecánica que se utiliza para calcular el RMR (Rock Mass Rating) de Bienawski, sólo que en lugar de parámetros geomecánicos como en la tabla de RMR son parámetros geometalúrgicos. La CGMB se aplica directamente sobre un modelo de bloques, donde de acuerdo a los parámetros como tener una relación entre su puntuación geometalúrgica, la cual indica el comportamiento (recuperación metalúrgica, uso de agua, químicos, etc) que tendrá el bloque al ser procesado en la planta. El modelo consta de cuatro parámetros distintos: Técnicos, Geológicos, Metalúrgicos y Económicos, donde solamente los geológicos y metalúrgicos tienen puntuaciones las cuales se asignan utilizando la CGMB. La aplicación del modelo se realizó en 26 bloques, dando como resultado 4 bloques con una muy alta puntuación, 2 con alta puntuación, 15 una baja puntuación y 5 una puntuación muy baja. Además, el modelo acusa que bloques como el B7PSZZ446 y el B8PSZZ446 que corresponden a bloques de baja puntuación (amarillos) tienen una mayor valorización que bloques de alta puntuación (naranjos) como el B3PZSS446, lo mismo ocurre con los bloques B9PZSS446, B7PZSS450 y B2PZSS464 que son bloques de baja puntuación (verdes), sin embargo, tienen una mayor valorización que bloques “amarillos” como B3PZSS464, B3PZSS467, B4PZSS467, B5PZSS467 y el B3PZSS473. Lo cual hace que el modelo cumpla con lo que dicta la Geometalurgia como ciencia, que en propias palabras sería que un bloque mineral debe ser analizado con todos los parámetros geológicos y metalúrgicos para poder así tener resultados esperados más exactos ya que aumentan la confiabilidad de la utilidad que se obtiene al procesar dicho bloque en comparación al método original de valorización de bloques el cual no contempla los parámetros geometalúrgicos y puede traducirse en recuperaciones menores o menos exactas a las estimadas.
The following work consists in the development of a geometallurgical model for an ionic clay deposit located in Penco, Biobío Region, owned by Biolantánidos (REE Uno Spa). The realization of this model consists first of the generation of a geometric classification table with all the parameters that are identified prior to the development of this work. The block geometallurgical classification table (Yamal’s CGMB) is a table similar to the geometric classification table used to calculate the Bienawski’s Rock Mass Rating, only instead of geometric parameters as in the RMR table they are geometallurgical parameters. The CGMB is applied directly to a block model, where the agreement to the parameters has a relationship between its geometric score, which indicates the behavior (metallurgical recovery, water use, chemicals, etc.) in the plant. The constant model of four different parameters: Technical, Geological, Metallurgical and Economic, where only geological and metallurgical have which are assigned using the CGMB. The model was applied in 26 blocks, resulting in 4 blocks with a very high score, 2 with a high score, 15 a low score and 5 a very low score. In addition, the model accuses that blocks such as B7PSZZ446 and B8PSZZ446 that correspond to low-scoring blocks (yellow) have a greater recovery than high-scoring blocks (orange) such as B3PZSS446, the same as with blocks B9PZSS446, B7PZSS450 and B2PZSS64 which are low-scoring blocks (green), however, have a greater recovery than “yellow” blocks such as B3PZSS464, B3PZSS467, B4PZSS467, B5PZSS467 and B3PZSS473. What makes the model comply with what Geometallurgy dictates as a science, which in own words would be a mineral block must be analyzed with all geological and metallurgical parameters in order to have more accurate expected results as they increase the reliability of the utility that is obtained when processing said block in comparison to the original method of valorization of blocks which does not contemplate the geometallurgical parameters and can result in minor or less exact recoveries than estimated.
