Vermikuliittilähteet

Vermikuliittilähteet refers to sources of vermiculite. Vermiculite is a naturally occurring mica-group mineral that undergoes exfoliation when heated. This exfoliation process causes it to expand into a lightweight, porous material. It is typically found in igneous rocks and can also form through hydrothermal alteration of minerals like biotite and phlogopite. Major commercial deposits of vermiculite are located in various parts of the world, including South Africa, Australia, China, and the United States.

The primary use of vermiculite is as an industrial mineral. Its excellent insulating properties, fire resistance, and absorbency make it valuable in several applications. In horticulture, it is widely used as a soil amendment to improve aeration, drainage, and moisture retention. It is also employed in construction for insulation and lightweight concrete, as well as in fireproofing materials and as a carrier for agricultural chemicals. The extraction and processing of vermiculite involve mining the raw ore, followed by heating it in a kiln to achieve exfoliation. The specific geological conditions under which vermiculite forms influence its purity and physical characteristics.
