Abstract
A process for production of minerals using an evaporation unit comprising an evaporation element for exposing thereof to the atmosphere for evaporation of a liquid solution therefrom. The evaporation element comprises an evaporation surface and a texture for deflecting the solution during movement along the surface, leaving minerals on the surface as a result of evaporation of the solution. The texture allows the minerals to detach from the element under the sole influence of normal forces of nature before the minerals reach a weight capable of damaging the evaporation unit. The process includes wetting the element with the solution, which at least partially evaporates and forms precipitated minerals, at least some of which are left on the surface; and letting the minerals detach from the surface solely under the influence of normal forces of nature before the minerals on the surface reach a weight capable of damaging the unit.
