• As the land so cleared fell into disuse, the soil began to leach and become more acidic, producing a suitable environment for the growth of heather and rushes.

  • However, leaching and groundwater leakage still causes some pollution.

  • In less leached yellower sands, the community (and B. aemula) is replaced by a taller heath containing B. serrata and B. oblongifolia.

  • Like most Adenanthos species it is common on deeply leached siliceous sandplain sand.

  • Locally known as Karrakatta Sand, it is almost certainly the leached remnants of coastal sand deposited by eolian processes in the late Pleistocene period, between 11,000 and 100,000 years ago.

  • Once the gold-bearing rocks were brought to the surface, the rocks were crushed, and the gold was separated out (using moving water), or leached out, typically by using arsenic or mercury (another source of environmental contamination).

  • The aluminium sulfate in it is converted to the insoluble aluminium oxide by roasting the alum with carbon, and the resulting product is leached with water to yield a Cs2SO4 solution.

  • The contamination of the karst underground waters is due to the large number of waste disposal sites leached by rainwater, as well as to the accidental overflow of various liquids.

  • The dumps of the past mining operations leach significant amounts of zinc and cadmium, and, as a result, the sediments of the Geul River contain significant amounts of heavy metals.

  • The gyromitrin is leached into the water where it will remain, therefore the parboiling water must be discarded and replaced with fresh water after each round of boiling.
  • Wikipedia: Gyromitra esculenta
  • The mine used a chemical extraction process known as vat leaching involving the use of a weak cyanide solution.

  • The plant distribution is influenced by the dunes' age as well as their moisture content, the deposits becoming less alkaline as calcium carbonate from animal shells is leached out of the sand to be replaced by more acidic humus from plant decomposition products.

  • The primary danger with such a course is that the waste is likely to come into contact with water, which could leach radioactive contamination into the environment.

  • The water content of the fumaroles' gases decreased, and water springs in the vicinity of Nevado del Ruiz became enriched in magnesium, calcium and potassium, which were leached from the magma.

  • The water content of the fumaroles' gases decreased, and water springs in the vicinity of Nevado del Ruiz became enriched with magnesium, calcium and potassium, leached from the magma.

  • To improve the leaching process in the gold cyanidation, lead(II) nitrate solution is added.

  • Van Erp used concrete from which alkali salts and calcium hydroxide leached and were transported into the rest of the construction.
