There are significant negative effects of exposure to spent lead ammunition on wildlife and human health. A joint statement was issued by nine UK shooting rural organisations 24th February 2020 intended encourage a voluntary transition non-lead shotgun within five years “in consideration wildlife, the environment ensure market for healthiest game products”. We dissected carcasses wild-shot common pheasants Phasianus colchicus sold or offered consumption in Britain season between 1st October...
Environmental Context. Acid sulfate soils are found in many low-lying coastal areas, but they can also be encountered inland areas of Australia and other parts the world. These typically contain iron sulfides, primarily pyrite (FeS2) mackinawite (FeS), products that result from oxidation these minerals. Acidic metal-rich waters produced when soil is oxidized by natural means or accelerated drained, which occurs it developed for agriculture urban use. In general, acid become a problem...
Cover systems that utilise the moisture store-and-release (S&R) concept rely on ability of cover material to possess sufficient retention capabilities.Infiltrating waters are then 'stored' within material, and subsequently 'released' atmosphere as evapotranspiration.As a result, net percolation (recharge) underlying waste is minimised.A key aspect achieving low rates manage high infiltration (resulting from intense long duration rainfall events) through development vegetative can (transpire)...
Rio Tinto Iron Ore (RTIO) manages eleven mines in the Pilbara region, Western Australia. Three of these have previously or are currently mining black shale that contains varying amounts pyrite. Several new deposits being evaluated and existing may progress below water table future, will also encounter this waste material. The presents not just an acid rock drainage risk but a spontaneous combustion risk. This paper management strategy provides overview relevant activities undertaken by RTIO....
This study developed an industry-applicable, thermal decomposition methodology for quantification of carbonate mineral acid neutralisation capacity (ANCtherm-carb) waste rock, tailings, and other mined materials. Standard titration-based methods ANC can be compromised due to contributions from silicate minerals, ion exchange, Fe-rich carbonates, transition metal carbonates. C emission (CO2 CO) was measured using IR in a N2 atmosphere. Cneut (wt%) calculated the at 800 or 1000 °C minus 400,...
There is an increasing need in mine closure studies for a toolbox of procedures designed specifically application to low sulfur waste types – help build confidence the generally accepted premise that these wastes have risk profile. Historically, characterisation efforts focused on materials with elevated sulfur. This warranted due greater associated acid and metalliferous drainage from potentially forming wastes. Test are well established. Regarding non-acid materials, geochemical can vary...
The North End Box Cut (NEBC) waste dump at Rio Tinto's Tom Price iron ore operation is an historic that contains estimated 2.6 Mt of potentially acid forming (PAF) shale material.The 75 ha in size and positioned on the edge site's current operational footprint.Construction NEBC began 1990s, PAF material was encapsulated within dump.However, does not meet standards for management or landform design, which were first developed 1999 but have been updated since to reflect changes industry...
