In the present article, a new tool to determine environmental sustainability, the energy impact index EII was developed to classify different iron mine projects according to two main parameters including energy consumption and CO2 emissions. The EII considers the characteristics of the mineral such as the quality, size, hardness, iron ore grade, reducibility, mineral-waste rate, and type of deposit, mining processes type of exploitation, ore processing, available technology, and transportation distance to cover.

de Minas, Universidad Politécnica de Madrid, ETSI Minas, ltp@coimce.com Received for review: March 17th, 2011; accepted: April 23rd, 2011; final version: May 2nd, 2011 ABSTRACT: In the present article, a new tool to determine environmental sustainability, the energy impact index (EII) was developed to classify different iron mine projects according to two main parameters including energy consumption and CO2 emissions.
The EII considers the characteristics of the mineral (such as the quality, size, hardness, iron ore grade, reducibility, mineral-waste rate, and type of deposit), mining processes (type of exploitation, ore processing, available technology), and transportation (distance to cover). KEYWORDS: Sustainability, iron, energy, CO2 emissions RESUMEN: A través de este trabajo se desarrolla una nueva herramienta de sostenibilidad ambiental (Índice de Impacto Energético, IIE) para la clasificación de los diversos proyectos en minas de hierro, analizando dos parámetros principales: el consumo de energía y las consecuentes emisiones de CO2.
El IIE tiene en cuenta diferentes propiedades del mineral (calidad, tamaño, dureza, ley, reducibilidad, ratio mineral-estéril y tipo de yacimiento), el proceso minero (método de explotación, mineralurgia o tecnología aplicada) y el transporte (considerando distancias recorridas). PALABRAS CLAVE: Sostenibilidad, hierro, energía, emisiones CO2 1.
INTRODUCTION 2.
PARAMETERS TO CONSIDER Mining sustainability has been of significant interest to the mining industry since the mid-1990s [1]. Currently, mining companies have different tools to show their commitment to the values of environmental sustainability (i.e., studies on mineral efficiency, life-cycle assessment, cost-benefit analysis, mining sustainability indicators, GRIs, environmental accounts, proto...
