• Saltpeter is the main ingredient of gunpowder and was obtained by leaching the earth from local caves.
• Saltpeter is the main ingredient of gunpowder and was obtained by leaching the earth from several local caves.
• Piper Cave, located near Monoville, contains the poorly preserved remnants of dozens of saltpeter leaching vats.
• DeKalb County was the site of several saltpeter mines, the main ingredient of gunpowder, and was obtained by leaching the earth from several local caves.
• A nitrate vulnerable zone can be designated as a response to an increase in nitrate leaching or increased use of nitrate fertilizers.
• The Mountain Lion Gold Mining company 100-ton mill used a combination of mercury plate amalgamation followed by MacArthur-Forrest cyanide leaching.
• Sowing green manure crops such as grazing rye to cover soil over the winter will help to prevent nitrogen leaching, while leguminous green manures such as winter tares will fix additional nitrogen from the atmosphere.
• It is more stable than dynamite, but can still suffer from "sweating" or leaching out nitroglycerine.
• Soil remineralization (in the sense of re-incorporating minerals, different from remineralisation in biogeochemistry) creates fertile soils by returning minerals to the soil which have been lost by erosion, leaching, and or over-farming.
• Escondida produces mainly copper concentrates, which are piped as a slurry down to the port of Coloso, where they are dewatered before shipping, and a smaller proportion of cathode copper from the leaching of both oxide and low grade sulfide ore.
• This is thought to have formed during Neogene to Quaternary weathering by the silicification of Upper Paleocene Lambeth Group sediments, resulting from acid leaching.
• According to a March 8, 2021 article in The Narwhal, concerns have been raised about selenium pollution leaching from Teck Resources' Elk Valley open pit coal mines' waste rock, which is upstream from the lake system.
• Streaks on the face of the cliffs come from groundwater leaching out of the rock and evaporating, leaving streaks of iron (red), manganese (black-white), limonite (yellow-brown), copper (pink-green), and other minerals.
• For many years, production came from the oxidized capping of the orebody, which only required leaching and then electrowinning the copper, but by 1951 the oxidized reserves were primarily exhausted.
• Although some manufacturers of burial vaults claim that their vaults are "green" (environmentally friendly) and prevent the toxic chemicals used in embalming from leaching into the surrounding soil, such claims are uniformly false since the vault cannot be hermetically sealed without causing it to rupture from the pressure of decomposing gases.
• However, most chalcocite occurs in the supergene enriched environment below the oxidation zone of copper deposits as a result of the leaching of copper from the oxidized minerals.
• Important factors that need to be considered when managing nutrients include (a) the application of nutrients considering the achievable optimum yields and, in some cases, crop quality; (b) the management, application, and timing of nutrients using a budget based on all sources and sinks active at the site; and (c) the management of soil, water, and crop to minimize the off-site transport of nutrients from nutrient leaching out of the root zone, surface runoff, and volatilization (or other gas exchanges).
• Removal or damage of the biota reduces the local capacity to retain water, which can exacerbate flooding and lead to increased leaching of nutrients from the soil.
• The hardpan is formed by leaching of surface- or tree-nesting seabirds' guano in the absence of burrowing animals.
• The leachate mixture is sealed in extraction vessel for general analytes, or possibly pressure sealed as in zero-headspace extractions (ZHE) for volatile organic compounds and tumbled for 18 hours to simulate an extended leaching time in the ground.
