Presentación Pataz - Geometalurgia

Aplicaciones Geometalrgicas a minerales en PoderosaExpositor:Ing. Nieves Ayvar Humala

La informacin ms importante que debe obtenerse y tenerse dentro de una planta de tratamiento son las caractersticas del mineral de alimentacin.

En un yacimiento donde las caractersticas del mineral varan en funcin a la zona de explotacin, es necesario tener identificados tales caractersticas en trminos de localizacin, interpretacin geolgica, explotacin, y desde el punto de vista metalrgico antes de su tratamiento en planta.INTRODUCCIN

Son varias las empresas que actualmente vienen desarrollando proyectos para desarrollar un adecuado programa de explotacin y tratamiento del mineral.

Aqu entra a tallar un nuevo concepto: Geometalurgia, trmino que busca involucrar las caractersticas, tanto geolgicas como metalrgicas del mineral, que tenga incidencia directa en su tratamiento en trminos de recuperacin.

El presente trabajo mostrar lo concerniente a los primeros trabajos de caracterizacin metalrgica de los minerales en Poderosa, el desarrollo de los trabajos que se viene realizando a nivel laboratorio, y algunos de los modelos matemticos que se estn obteniendo para este fin.

Caracterizar zonas geolgicas en la mina que tengan alguna implicancia (positiva o negativa) en el proceso de tratamiento, especialmente en la recuperacin Modelo Geometalrgico

Encontrar modelos de recuperacin que interrelacionen todas las variables que puedan incidir en los resultados de tratamiento Modelos metalrgicos

Encontrar las posibles combinaciones de mineral procedente de diferentes zonas geolgicas para su adecuado tratamiento en planta.

Optimizar el tratamiento en planta para evitar variabilidad en recuperaciones y consumos de reactivos.OBJETIVOS

Conseguir la participacin conjuta de las tres reas involucradas (geologa, minas, y metalurgia).Discusin de trminos, indicadores y parmetros importantes a ser evaluados.Definir caractersticas metalrgicas a determinar.Capacitacin.Realizacin de pruebas metalrgicas en laboratorio.Acondicionamiento del ambiente de laboratorio para el desarrollo de algunas pruebas especiales.Procesamiento de datos.Discusin de resultados.ESTRATEGIAS

Para llevar a cabo la caracterizacin metalrgica, se han recibido en laboratorio 03 muestras de mineral procedentes de diferentes zonas geolgicas, las cuales corresponden a las vetas de:A. JIMENA-PP0112-024B. KAROLA-KA0112-060C. CONSUELO-CV0201-001

Sobre estas muestras se han programado la realizacin de pruebas metalrgicas a nivel laboratorio, las cuales se han dividido en 03 fases de realizacin:1 fase:Caracterizacin2 fase:Lixiviacin3 fase:Diagnstico por lixiviacinCARACTERIZACIN METALRGICA

Los resultados obtenidos en cada prueba han sido traducidos a modelos matemticos en su primera etapa. Ms adelante se deber aquel modelo que relacione la recuperacin de oro con todas las variables que puedan interferir en los resultados.

Estos modelos servirn para estimar la recuperacin posible a obtener en planta por cada zona o veta, predecir los consumos de reactivos, cuan refractario a un determinado proceso puede ser.

Asimismo se debe contar con toda la informacin correspondiente a las variables independientes a las frmulas obtenidas.
