Engagement At its simplest, engagement is communicating effectively with the people who affect, and are affected by, a company’s activities (its stakeholders). A good engagement process typically involves identifying and prioritising stakeholders, conducting a dialogue with them to understand their interest in an issue and any concerns they may have, exploring with them ways to address these issues, and providing feedback to stakeholders on actions taken. At a more complex level, engagement is a means of negotiating agreed outcomes over issues of concern or mutual interest. Enterprise-wide risk The overarching risk management framework that defines the framework scope of risk types and the key risk management processes implemented across the whole organisation to manage risk inan holistic and systematic way. Entrainment: The water that is contained in the rock or coal after it is processed. The moisture content after processing is usually greater than before processing. Environmental impact Detrimental harm to the environment. Environmental indicator A parameter (or a value derived from a parameter) which provides information about an environmental phenomenon Environmental Management System (EMS) A tool for managing an organisation’s impact on the environment. It provides a structured approach to planning and implementing environmental protection measures. Evaporation The process by which water is converted from liquid to vapour and is lost to the atmosphere. Event tree analysis A technique used to describe the range and sequence of possible outcomes of an event. Exploration The search for mineral deposits up to discovery and includes the delineation of the deposit by means of drilling and sampling. Extended producer responsibility The application of responsibility for managing the environmental and social impacts of a good at its end-of-life to the producer (or brand name) of the good. Factor of safety The factor by which the resisting actions exceed the disturbing actions. Failure modes The mechanisms by which a tailings storage facility may fail. Filter cake The semi-solid structure formed on the application of pressure during filtration of a slurry. A GUIDE TO LEADING PRACTICE SUSTAINABLE DEVELOPMENT IN MINING 187
Final void The remnant open pit left at mine closure. Fine (coal) reject The fine fraction of the mineral matter removed from run-of-mine coal by washing. Flocculants Chemical additives that facilitate the agglomeration of tailings particles to aid and speed up their sedimentation and consolidation. Fly-in, fly-out Fly-in, fly-out operations utilise a moveable workforce, where employees reside some distance from the operation and are flown to site to work for a period of time and then flown out again. Footprint The surface area covered by the mine and its associated infrastructure. Freeboard The elevation of the crest of the containment wall above the tailings surface, which provides for the storage of storm water. Functional ecosystem An ecosystem that is stable (not subject to high rates of erosion), effective in retaining water and nutrients and is self-sustaining. Geomembrane A manufactured low permeability sheet such as high density polyethylene (HDPE). Geotechnical The engineering of the ground and or earthern structures. Gradual risk A gradual risk event occurs over a long period of time and is representative of many types of pollution of the environment. For example slow leaks from hydrocarbon containment, acid seepage or emissions to the atmosphere. Groundwater Water beneath the earth’s surface that fills pores between porous media—such as soil, rock, coal, and sand—usually forming aquifers. In some jurisdictions the depth below the soil surface is also used to define groundwater (although different states may use different depths). Hazard A hazard is a source of potential harm. Heap leach Using chemicals to dissolve minerals or metals out of an ore heap. During heap leaching of gold, a cyanide solution percolates through crushed ore heaped on an impervious pad or base pads. 188 LEADING PRACTICE SUSTAINABLE DEVELOPMENT PROGRAM FOR THE MINING INDUSTRY
