High rate thickener A thickener through which a slurry is passed at a high rate, with limited residence time, allowing a high flocculant dose. Hydraulic conductivity Otherwise known as (water) permeability; a measure of the ability of a porous material to pass water. Hydraulic backfill Fill that is placed as a fluid. Hydroseeding Spraying a mixture of paper or straw mulch, containing seed, fertiliser and a binding agent, onto a slope which is too steep or inaccessible for conventional seeding techniques. Inactive site A mining or mineral processing area which is currently not being operated but which is still held under some form of title. Frequently such sites are referred to as being under ‘care and maintenance’. Indigenous Land Use Agreements (ILUA) ILUAs are used to negotiate with Indigenous people with native title interests regarding the doing of acts affecting native title. Under the Native Title Act, a registered ILUA is legally binding on all people who hold native title over the agreement area, whether or not they are party to the agreement. Interested party A person, group or organisation with an interest in the process of, or outcome of, mine closure. Key in Construction of a back-filled trench to reduce seepage or improve the stability of an earthen embankment. Kinetic testing Dynamic testing of acid generation, including the effect of reaction time. Lag time Time delay between the disturbance or exposure of acid generating materials and the onset of acidic drainage. Landholder The owner of freehold land, the holder of leasehold land, or any person or body who occupies or has accrued rights in freehold or leasehold land. Leading practice Best available current practice promoting sustainable development. Licence-to-operate The permission government gives to the mining industry to mine and produce minerals from specific operations through formal legislative and legal agreements.

Life Cycle A company needs to examine each step in the life cycle of a product, including those that are easily overlooked, such as the fate of the product after its useful life. These steps will typically include the extracting and processing of materials; manufacturing, transportation and distribution; use, reuse, maintenance; recycling and final disposal. Liner A low permeability base comprising compacted clay, and/or a geomembrane or geosynthetic (clay in a geotextile “sandwich”). Local provenance Plants whose native origin is close to that where they are going to be planted (for example in the same local area). Low grade ore stockpile Material that has been mined and stockpiled, with sufficient value to warrant processing, either when blended with higher-grade rock or after higher-grade ore is exhausted, but often left as ‘waste’. Materials stewardship Materials stewardship overarches the stewardship approach since it applies to resources, processes and products and, therefore, covers the full life cycle. It describes an integrated program of actions aimed at ensuring that all materials, processes, goods and/or services that are produced, consumed and disposed along the value chain are done so in a socially and environmentally responsible manner. Moonscaping A technique using dozer blades to scallop a pattern which helps prevent erosion. Monte Carlo simulation A method for iteratively evaluating a deterministic model using sets of random numbers as inputs. The method is often used when the model is complex, nonlinear, or involves more than just a couple uncertain parameters. Native Title In the 1992 Mabo decision, the High Court of Australia recognised that the Meriam people of the Torres Strait held native title over part of their traditional lands. The High Court found that the common law of Australia recognises rights and interests to land held by Aboriginal and Torres Strait Islander people under their traditional laws and customs. Natural analogue An unmined landform to which a mined landform may be compared to develop sustainable post-mining landforms. NAG Net Acid Generation test, also referred to as “single addition NAG test”. Peroxide is used to oxidise any sulfides in a sample, then any acid generated during oxidation may be partially or completely consumed by neutralising components in the sample. Any remaining acidity is expressed as kg H2SO4 per tonne. A “sequential NAG test” involves a series of NAG tests on a sample. This may be required if a sample cannot be fully oxidised using the conventional NAG test. 190 LEADING PRACTICE SUSTAINABLE DEVELOPMENT PROGRAM FOR THE MINING INDUSTRY
