GLOSSARY AND ACRONYMS Abandoned mine or site An area formerly used for mining or mineral processing, where closure is incomplete and for which the title holder still exists. Aboriginal Land Council Aboriginal Land Councils are the peak bodies in Indigenous affairs within Australian states and the Northern Territory. Acid A measure of hydrogen ion (H+) concentration; generally expressed as pH. Acid is not equivalent to acidity (see definition below). Acid and metalliferous drainage Acid and metalliferous drainage, traditionally referred to as “acid mine drainage” or “acid rock drainage”, includes both acidic, metalliferous drainage, and near-neutral but metalliferous drainage. Acid mine drainage Acidic drainage from mine wastes resulting from the oxidation of sulphides such as pyrite. Acid-based accounting An analytical technique that determines the maximum potential acidity that can be generated by oxidisation of sulphides compared with the neutralisation potential of rock or tailings. It is also used to predict the potential of the material to be acid-producing, neutral or alkali-producing. Acidity A measure of hydrogen ion (H+) concentration and mineral (latent) acidity; generally expressed as mg/L CaCO3 equivalent. Measured by titration in a laboratory or estimated from pH and water quality data. Active treatment Process in which chemicals or natural materials are added to AMD to improve water quality. Operator control can vary from relatively simple batch treatment to a sophisticated computerised treatment plant with multiple additives and detailed process monitoring and control. Active treatment involves regular reagent and labour inputs for continued operation, compared with passive treatment (see below) that only requires occasional maintenance. Active treatment systems can be engineered to deal with any acidity, flow rate and acidity load. Adaptive management A systemic process for continually improving management policies and practices by learning from the outcomes of operational programs. The ICMM Good Practice Guidance on Mining and Biodiversity refers to adaptive management as ‘do-monitor-evaluate-revise’. A GUIDE TO LEADING PRACTICE SUSTAINABLE DEVELOPMENT IN MINING 181
Alkaline cover A soil cover (eg. water shedding or store-and-release cover (defined below)) that has an “alkalinity generating” component deployed above, within or at the base of the cover. The aim is to minimise infiltration and ensure that any water that migrates through the cover contains substantial alkalinity Analogue Unmined feature against which a mined feature may be compared. ANC Acid Neutralising Capacity, expressed as kg H2SO4 equivalent per tonne. Angle of repose The maximum angle from horizontal at which a given material will rest on a given surface without sliding or rolling. APP Acid Producing Potential, expressed as kg H2SO4 per tonne. AS/NZS 4360 Risk Management Standard The Australian and New Zealand 4360 Risk Management Standard is a generic framework for establishing the context, identifying, analysing, evaluating, treating, monitoring and communicating risk. Backfilling Refilling of an excavation or void. Barren pond Storage pond for solution from which gold has been extracted. Basal layer The soil or rock foundation layer at the base of an engineered structure. Baseline studies Studies undertaken to describe the conditions that exist before an action is taken. Batter slope Recessing or sloping a wall back in successive courses. Benthic Referring to organisms living in or on the sediments of aquatic habitats (lakes, rivers, ponds, etc.). Berm A horizontal shelf or ledge built into an embankment or sloping wall to break the continuity of the otherwise long slope for the purpose of strengthening and increasing the stability of the slope, to catch or arrest slope slough material, or to control the flow of runoff water and erosion. Biodiversity The variety of life on our planet, measurable as the variety within species, between species, and the variety of ecosystems. See Section 2.1 of this booklet for a full definition. 182 LEADING PRACTICE SUSTAINABLE DEVELOPMENT PROGRAM FOR THE MINING INDUSTRY
