What is leaching in extraction?

From Wikipedia, the free encyclopedia. Leaching is a process widely used in extractive metallurgy where ore is treated with chemicals to convert the valuable metals within into soluble salts while the impurity remains insoluble.

What happens when soil leaches?

Leaching happens when excess water, through rainfall or irrigation, takes water-soluble nutrients out of the soil. Often, this excess nutrient-rich water flows into rivers, streams, and lakes, or is absorbed into groundwater, which may affect local community drinking water.

How do I leach my soil?

To leach plants, pour excess water on the soil and let it drain completely. The amount of water used for leaching should equal twice the volume of the pot. Keep the water running through the soil to wash out the salts. If a layer of salts has formed a crust at the soil surface, remove the salt crust before leaching.

What is leaching and where does it occur?

In layman’s terms, leaching in soil means leaking of water down the soil. The soil is more like a sponge. When it rains, the top part of the soil absorbs as much water, keeping the moisture available for the plants. However, when the soil is filled with water more than it can hold, leaching occurs.
