الإنجليزية - الإنجليزية
The extraction of a soluble metallic compound from ore by dissolving the metals in a solvent
The process where material in the soil (such as nutrients, pesticides, etc ) are washed into lower layers of soil by the downward movement of water
Flushing out of dissolved or suspended materials from the soil, solid waste, or another medium by the action of percolating water
The process by which soluble materials in the soil, such as salts, nutrients, pesticide chemicals or contaminants, are washed into a lower layer of soil or are dissolved and carried away by water Also see Leachate
The removal of materials in solution from soil or rock to ground water; refers to movement of pesticides or nutrients from land surface to ground water
present participle of leach
To remove a soluble substance from a material by dissolving it in a liquid, and then removing the liquid from what is left
the removal in solution of soluble minerals and salts by water seeping through soil or rock
the process in which a soluble metallic compound is extracted from ore by dissolving the metals in a solvent; see cyanidation
the dissolution of soluble constituents from a rock or orebody by the natural action of percolating water
the natural process by which water transports salts and other soluble materials through the soil
A process of soil nutrient removal through the erosive movement and chemical action of water
The process by which chemicals are dissolved and transported through the soil by percolating water Pesticides and nutrients from fertilizers or manures may leach from fields, areas of spills, or feedlots and thereby enter surface water, groundwater, or soil Leaching from concentrated sources such as waste sites and loading areas vulnerable to spills can be prevented by paving or containment with a liner of relatively impermeable material designed to keep leachate inside a treatment pond, landfill, or a tailings disposal area Liner materials include plastic and dense clay
The process by which soluble matter is dissolved in groundwater and carried downward and radially through the soil
The act of dissolving the soluble portion of a solid mixture by some solvent An example is the dissolving of inorganic or organic contaminants from refuse in a landfill by infiltrating rain water
The process in which nutrients and other compounds (e g , calcium) in the upper layers of soil are dissolved and carried to lower layers and, in some cases, to groundwater
The process by which substances are released from the soil by dissolving in fluids, usually rain and surface water, and are carried down through the soil To pass through the soil due to rain or groundwater moving through contaminated materials Leaching can cause hazardous substances to enter the soil, surface water, or groundwater
The removal of nutrients, chemicals or contaminants from the soil by water movement through the soil
process of dissolving, washing, or draining earth materials by percolation of groundwater or other liquids
The process by which soluble constituents are dissolved and filtered through the soil by a percolating fluid Leakage A species of ions in the feed of an ion exchanger present in the effluent
Process by which soluble materials are dissolved and carried through the soil by a percolating liquid
Process in which water removes and transports soil humus and inorganic nutrients in solution
The downward transport of dissolved or suspended minerals, fertilizers, and other substances by water passing through a soil or other permeable material
v. Loss of soluble substances and colloids from the top layer of soil by percolating precipitation. The materials are carried downward and are generally redeposited in a lower layer. This transport results in a porous and open top layer and a dense, compact lower layer. In areas of extensive leaching, the remaining quartz and hydroxides of iron, manganese, and aluminum form laterite. In such areas rapid bacterial action results in the absence of humus in the soil, because fallen plant material is oxidized and the products are leached away
The process by which soluble materials in the soil, such as nutrients, pesticide chemicals or contaminants, are washed into a lower layer of soil or are dissolved and carried away by water
This is a common problem in sandy soils, which do not hold water well Nutrients (and other substances) in the soil may be dissolve in water The water, thanks to gravity, is pulled downward and may carry the nutrients with it, leaving the soil depleted Slow leaching by adding humus to the soil The humus will slow water's downward movement and give soil organisms and plants more time to absorb the dissolved nutrients

leach
To dissolve from a rock For example, when acidic water passes through fractured rocks, soluble minerals leach, or dissolve, from the rocks
