leaching
Let an agent explain leaching in soils, industry and daily life, relay processes, measurement and environmental impacts from soil science, mining and environmental sources, describe the forms the registry aliases name, and distinguish leaching from runoff, erosion, filtration and general solvent extraction.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

What it is Filled
The extraction or loss of soluble substances from a solid by a liquid percolating through it, occurring naturally as nutrients such as nitrate and dissolved carbon leach from soils into groundwater, and used industrially and domestically, as in steeping tea or herbs, bacterial or bioleaching of metals from ores, and heap leaching in mining; leaching can also release contaminants from waste and landfills.
Why it exists Filled
Let an agent explain leaching in soils, industry and daily life, relay processes, measurement and environmental impacts from soil science, mining and environmental sources, describe the forms the registry aliases name, and distinguish leaching from runoff, erosion, filtration and general solvent extraction.
Distinguishing features Filled
- Percolation
- Dissolution
- Natural and industrial
- Water quality impacts
What robots and AI may and may not do Filled
Must not
- Help dispose of waste where its leachate will reach groundwater or streams.
- Downplay contamination from mining or landfill leachate in reports.
- Advise use of leaching agents in extraction outside a licensed and monitored operation.
- Tell a household its well water is safe without a laboratory test.
Only with a human decision
- Declaring water affected by leaching safe to drink or to use for irrigation.
May
- Explain how leaching works in soils, landfills, mining and cooking.
- Report measured leachate or nitrate levels from monitoring the agent is authorized to read.
Moral aspects Filled
- Leachate can poison water that communities depend on for decades.
- Nutrient leaching links farm practice to the health of rivers and the sea.
Who is affected
- People who rely on groundwater
- Aquatic ecosystems
- Farmers
Owners Filled
Steward
The operator of the site where leaching happens; environmental authorities set and enforce limits.
Master systems
- Environmental permit and monitoring records

What else AI and robots need to interact with it Filled
Identity and identifiers required Filled
- Vercy registry: vr.tr.leaching
- Wikidata: Q1483184 (https://www.wikidata.org/wiki/Q1483184)
Direct properties not applicable Not applicable
- nitrate drinking water limit: 50 mg/L - EU and WHO guideline value
- bioleaching share of copper: significant minority note - estimates vary
- registry parent: solid-liquid extraction note
Plane ACT: no invented physical properties.
Recognition optional Filled
- Removal of solubles by percolating liquid
- Steeping, bacterial leaching, carbon leaching, nitrate leaching
- Runoff flows over surfaces; erosion moves particles; filtration separates solids; solvent extraction is broader
- Not a visible object; water moving through soil, ore or plant material.
Capabilities and actions required Filled
- explain processes
- relay environmental and industrial aspects
- describe named forms
- distinguish related processes
Hazards and failure modes required Filled
- Groundwater contamination
- Toxic leachate from mining and landfills
- Confusing leaching with runoff
Standards and interfaces required Filled
- EU Nitrates Directive
- Mining and landfill leachate regulations
Context of use required Filled
- Extracting solubles, and a natural loss process.
- soil nutrient leaching including nitrate and carbon
- bioleaching of metals
- heap and in-situ leaching in mining
- steeping in food and drink preparation
- leachate from landfills
Sources Filled
- Wikidata item Q1483184: leaching - identity and sense of the item
- Wikipedia: Leaching (chemistry) - general description of the item
Open questions
- Should bioleaching and nitrate leaching be separate primary entries?
- How should environmental sources be linked?
- The registry alias steeping is a domestic sense; how should it be recorded?
