The liquid that collects in a leaching basin at landfill sites, known as leachate, serves to collect and transport contaminants that have leached from the waste materials. It is generated when water, including rainwater and snowmelt, percolates through the waste, dissolving various substances in the process. The leachate is then treated to prevent environmental contamination and protect groundwater and surface water resources. Proper management of leachate is crucial for minimizing the ecological impact of landfills.
Removal of nutrients from soil is called leaching
Leaching is a process in which minerals are extracted from a solid by dissolving it into a liquid. Calcification is the build up of calcium salts in body tissue.
Leaching is the process of extracting substances from a solid by dissolving them in a liquid. This method is commonly used in mining to extract metals from ores. The liquid used is usually a solvent that selectively dissolves the desired materials, which can then be separated from the solid residue.

Leaching in science refers to the process of extracting soluble substances from a solid by percolating liquid through it. This can involve the removal of minerals from soil, the extraction of chemicals from a material, or the dissolving of contaminants from a solid matrix.
In a U-tube manometer, the liquid that collects in the U-tube is typically a fluid such as water, mercury, or another liquid with known density. This liquid is used to measure pressure differences between two points, as the height difference between the two columns of liquid indicates the pressure difference. The specific liquid chosen depends on the application and the pressure range being measured.
Leaching is one of many solid-fluid separation processes that are carried out in the chemical, mineral and related industries. In fact, it is one of the oldest unit operations in the chemical industries. The fundamental principle behind leaching is the removal of a soluble material from an insoluble, permeable solid phase. The soluble fraction, solid or liquid, may exist mechanically in the pore structure of the insoluble material or chemically combined with that material. This soluble material is removed through dissolution in a dissolving solvent. The most familiar example of leaching is the extraction of tea and coffee, and most importantly mineral recovery. The rate of leaching (extraction) is affected by many physical and chemical phenomena. Mass transfer and equilibriumphenomena obviously playmajor roles. The process of leaching consists of the following steps: (i) The solvent diffuses into the solid phase; (ii) The diffused solvent dissolves the solutes (i.e. transfer the solute to the liquid phase). Leaching is always followed by solvent recovery, which involves another mass transfer operation; such as filtration.
- open-pit mining - underground mining - leaching - recovery from solid or liquid wastes, phosphates, etc.
water will collect at the bottom, because of its higher density compared to kerosene
The term "lixivated" typically refers to something that has been dissolved or washed out in a liquid, especially in the context of chemical processes or leaching. It often describes the process of extracting soluble components from a solid material by soaking or washing it with a liquid.

When soil becomes more liquid, it becomes saturated with water and can lead to problems like waterlogging and reduced aeration for plant roots. This condition can hinder plant growth and cause nutrient leaching.
