Veesorteerimises

Veesorteerimises, also known as water sorting or hydrodynamic sorting, is a process that utilizes the buoyancy and drag properties of water to separate materials based on their density and size. This technique is employed in various industrial and natural settings to achieve separation.

In essence, water sorting relies on the principle that objects with different densities will behave differently when suspended in a flowing fluid. Denser materials tend to sink faster or require a stronger current to remain suspended, while less dense materials are carried along more easily by the water flow. Similarly, the size and shape of particles influence the drag forces exerted by the water, affecting their movement and separation.

Common applications of veesorteerimises include mining and mineral processing, where it is used to concentrate valuable ores from waste rock. In environmental management, it can be applied to separate recyclable materials or to remove pollutants from water bodies. For instance, in gold panning, a simple form of water sorting, the denser gold particles settle at the bottom of a pan while lighter sand and gravel are washed away. The effectiveness of veesorteerimises is dependent on factors such as water flow rate, particle characteristics, and the design of the sorting apparatus, which can range from simple sluice boxes to more complex hydrocyclones.
