What SMI-CMLR Does

Over the years the CMLR has developed research expertise and knowledge that has spanned the realms of Environmental Geochemistry (“To understand and predict the source, transformations and fate of contaminants”), Landform Stability and Evolution (“To identify properties and processes which define stability of successfully-functioning landforms”), Soil-Plant Systems (“To develop technological solutions for rehabilitating anthropogenic soil-plant systems”), and Landscape Ecology (“To rigorously assess the long-term outcomes of mining activities on ecosystem function”).

More recently, these themes were further developed and built into three Groups, namely Ecosystem Assessment, Restoration and Resilience, Ecological Engineering of Mine Wastes (Soil Plant Systems) and the cross-disciplinary, Life Cycles of Mines and Metals.

Life Cycle of Mines and Metals

Life Cycle of Mines and Metals

The program has an integrative focus on environmental impacts, social implications, technical innovations and economic factors along the metal value chain and over the life of a mining project or operation. This program provides a multi-disciplinary approach to solving some of the key issues in the industries, with a current focus on creating better value from mining waste (waste rock, overburden and tailings) and mine closure.

 


Projects within this program

Developing a process for estimating long‐term salinity generation rates to predict salinity levels in coal mine final voids and the residual risk to receiving surface water or groundwater environments Building a tool for knowledge sharing and dissemination of mine rehabilitation and closure in the coal industry http://mrcwiki.org.au Identifying the links between climate change, raw material supply and environmental risks Examining the feasibility of mine tailings reprocessing to improve overall metal recovery and minimize the residual environmental risk Identifying economically viable options for the recycling of metals from end-of-life products and industrial waste in Australia wealthfromwaste.net

    Ecological Engineering of Mine Wastes

    Synchrotron images of nickel hyperaccumulator Alyssum murale seeds; copper metallophyte community in north-western Queensland; rehabilitated landform at an open-cut coal mine; nickel hyperaccumulator growth trial in Sabah, Malaysia

    The program currently focuses on two key areas: the discovery and utility of metallophyte plants; and, the recovery and sustainability of disturbed land. The program further leads a suite of projects that assess the environmental impacts of mining activities and disturbance on ecosystems, from which innovative approaches to restore ecosystem services are developed.

    Ecological Engineering of Soil-Plant Systems

    discovery of new knowledge and technologies relating to ecological engineeringThe program currently focuses on the discovery of new knowledge and technologies relating to ecological engineering and the rehabilitation of metal mine tailings and alumina refinery residues. Projects encompass bioweathering of primary minerals in tailings, eco-engineered pedogenesis of tailings, bio-geo-polymerization of tailing minerals for hardpan formation, and the biogeochemistry of the tailings-soil-plant continuum.
