Mineral processing is a form of extractive metallurgy that separates valuable minerals from the ore into a concentrated, marketable product. Mineral processing is also known as mineral dressing. Mineral processing is conducted at the site of the mine and is a highly mechanical process, with oversight from a central control room.
Mineral uptake is the natural process in which all the essential minerals enter the plant's cellular material, typically following the same pathway as water. The uptake of mineral nutrients occurs at both the roots and the leaves. The process of uptake or transport of mineral nutrients is carried out by the plant cells in two different ways:
