*Biodynamic salt.

The sensitive crystallization of salt.

The Earth is immersed in our solar system and planetary forces leave their mark on the morphology of plants. Biodynamic farmers use this knowledge to choose in practice the appropriate dates for planting, tilling, treatments and harvesting, according to the cosmic forces active at the moment. These cosmic effects have been investigated by Hartmut Spiess (of the German Institute for Biodynamic Research).

Light and the gravitational force of the Moon act on the Earth. Both experience fluctuations. The high tide occurs in the part of the planet closest to the Moon, but when it is aligned with the Sun and the Earth, the points of solar and lunar attraction coincide and result in states such as spring tides (with very high tides and Very low). Low and high tide also appear in the earth's crust: with a period of about 12.5 hours, the Moon travels the earth's surface.

¨… let us remember that every time the soil is worked, cosmic forces are introduced into it and that they can positively or negatively influence the results of these actions. ¨

Since ancient times, the planets have been divided into interiors (between the Earth and the Sun: Moon, Mercury, Venus) and exteriors (Mars, Jupiter, Saturn). The inner planets work on plant growth, either directly through the atmosphere, or indirectly through water, humus, or calcium (limestone, potassium, and sodium). The influences of Mars, Jupiter and Saturn are channeled through heat and silica (quartz, feldspar, mica); they flow through the silica content of the soil and from there up through the interior of the plant, expressing themselves in the colors of the flowers, and in the fruit and seed production.

Rudolf Steiner describes, in his Agriculture Course, how clay has the ability to unite both forces and thus make them accessible to the plant: “Clay carries within it solar impulses, and unites terrestrial materials with the forces of the cosmos. This happens when a correct combination of siliceous substances and calcareous substances with humus has taken place. If the humus contained only one of these two substances, we would get plants with strange shapes”.

Currently, the company Hnos. Úbeda GoldSal, takes all these theories further in situ, in the salt pans, with sunlight, the influence of the Moon, and the Cosmos within the Bahía de Cádiz Natural Park, and reaching the conclusion that by combining all these factors, there are extraordinary effects on the chemical composition of the minerals (salt), their morphology and even on the total volume of production.


*Cryosalt® (Cryogenic salt) - Evolution salt.

All great scientific discoveries are initially hypotheses, that formulated through the collection of information and data, solve a scientifically based problem.

Our knowledge and research in the field (NaCl), led us to solve the current equation for changes in the time, by which a liquid becomes a solid, through a scientific epistemological theory, and with the which, we open a new window to discovery.

Fruit of the invention of new methodologies, we present to Cryosalt® the new process of formation of a solid (Crystal) from saturated brines, using the combination of evaporation and cooling with Nitrogen, obtaining salt crystals of high purity.

The process is previously carried out in brine evaporation ponds to obtain the solution that later we are going to subject to extreme conditions of cooling with nitrogen, so that the solvent is suddenly oversaturated in an adiabatic process of intermolecular force, producing crystallization by ionic bond with polarization, maximizing attractions between opposite charges, giving rise to the formation of saline crystals of great purity and perfect geometry.

This happens when in the arrangement of charged particles or ions, the positives are surrounded by negative as first neighbors and vice versa.

Each Na+ ion has six Cl- ions around it, placed at the vertices of an octahedron, while in turn, each Cl- ion is within an octahedron formed by six Na+ ions. For this reason, the coordination number of the Na+ is 6:6.


  • B: Nucleation rate (nuclei formed per unit of time and volume of solvent)
  • N: Number of nuclei formed per unit volume of solvent.
  • t: Time.
  • k, i: Empirical parameters.
  • (C-C*): Supersaturation.
  • C: Concentration of the solute in the solution.
  • C*: Solute saturation concentration.


*BEC® project (Balsa - Experimental - Crystallization): The salt of the future.

Why BEC®?

Every era of humanity can be symbolised, characterised and defined by something singular, something incredibly simple. The absence of which would make life as we know it all but impossible. 

In a by gone age, communities recognised salt as a requirement for life. It was used to preserve food and thus sustain life. So important was this substance, it was used as a form of currency giving rise to the word salary. We believe and recognise that the 21st century is defined by advances in science, technology and innovation, always looking for sustainability.


- BEC® Project is intended to contribute a grain of salt to science, for this, Hnos. Úbeda GoldSal SL., will develop new uses in a traditional salt-pans, in which actions will be carried out for the study and development of new evaporation methodologies, in which the saturation of brines will be analyzed, and thus be able to determine which process is more feasible.

- BEC® Innovation is the change that introduces new features, and that refers to modifying existing elements in order to improve them, although the implementation of totally new elements is also possible.

- BEC® Technology is the set of systematic actions whose destination is the application of science for resolution the main problems of the Salt-pans, that will allow us to design, create, facilitate and efficiently solve in a sustainable way the growing needs of mining exploitation. With the adaptation of these technologies to the environment without causing a depletion or degradation of material resources and energy.

This project will include different experimental models, where brine crystallization rafts will be taken, rafts that will only be for the exclusive use of scientific research, in which a specific crystallization environment will be created, to reduce evaporation time. With the innovation of this project, a production of salt will be sought 365 days, this will motivate the acquisition and dissemination of scientific knowledge.

These rafts are classified as follows:

  • Greenhouse raft.
  • Raft without filtration.
  • Raft with sprinklers.
  • Solar panel raft.
  • Ultrasound raft.
  • Raft of infrared lamps.
  • Potash raft.
  • Lithium raft (Li)
  • Magnesium Chloride raft (MgCl2)
  • Calcium Chloride raft (CaCl2)
  • Raft of Artemia Salina.


*UAE Sea Salt: The Desert Flower.

One of the main objectives of this project, is to reflect the suitability of a unique environment in the world such as the UAE , since its climate and geomorphological characteristics, as well as the proximity of the sea, would provide the ideal place to obtain high quality sea salt.
Here each of the basic "special" characteristics necessary for the production of sea salt are unified.

Salt is usually harvested in large tracts of land near the coast where the action of the Sun and the winds favors the evaporation of sea water to saturation and subsequent crystallization.


Extension plane with an annual salt production of 2.000.000 Tons/year.


The shape of this unique salt mine is designed so that the end result be, the image of the Flag of the United Arab Emirates. Not only its design is innovative. Its surface is a milestone worldwide, reaching an area of 8.200 ha. 

As we have already explained previously, Sea Salt is obtained from the evaporation of a brine, which is based on an evaporation of a saline solution increasingly concentrated until the salt precipitates in the background.

These maritimes extensions of solar evaporation salt, can be by artificial water inlet of sea by pumping, or natural entrance of water, by the effect of the tides. Seawater is an inexhaustible source of salt because about 2.7% (by weight) is NaCl, or in other words 78 million tons per cubic kilometer of seawater, giving this method a cheap and inexhaustible form salt.

We conclude, that based on a few climatic exceptional conditions, and resting on the commercial exclusive possibilities of the zone, we have been able to describe and reflect the convenience of the creation of a salt mine located in the desert of UAE, whose surface and location make it THE MOST IMPORTANT SALT MINE IN THE WORLD.
