Resumen:
Un instituto de investigación eslovaco ha desarrollado un nuevo ferrofluido compuesto por tres componentes básicos: un líquido básico, un material magnético sólido y un agente estabilizante. El ferrofluido es un medio especial y su producción y densidad se ajustan bajo campos magnéticos. Un ferrofluido puede aplicarse como medio de separación pseudo-pesada en el proceso de separación magnetohidrostática o como agente humectante. El instituto busca socios con el fin de establecer acuerdos de joint venture o licencia.

Tittle:
A Slovak research institute is offering a ferro-fluid production applicable in the treatment of primary or secondary raw materials
Summary:
A Slovak research institute has developed a new ferro-fluid. It is composed of 3 basic components: basic liquid, solid magnetic material, and the stabilising agent. Ferro-fluid is a special medium, and its production and density are adjustable under magnetic field. Ferro-fluid can be applicable as a pseudo-heavy separation media in the process of magneto-hydrostatic separation or as wetting agent. The institute is looking for partners to cooperate via joint venture agreement or license agreement
Description:
Ferro-fluid is composed of 3 basic components: basic liquid, solid magnetic material, and the stabilising agent. The "carry" liquid is an arbitrary liquid, the magnetic properties of which can be improved, for example water, kerosene, oil, etc. The carriers of the magnetic properties of ferro-fluids are single-domain nano-sized magnetic particles. The role of the stabilising agent is to prevent the colloidal particles from aggregation.

There are two ways of application of ferro-fluids in the treatment of primary and secondary raw materials:
- As a pseudo-heavy separation medium in the process of magneto-hydrostatic separation (a process analogical to the treatment of materials of varying density in heavy liquids). Gradient magnetic field acting on the ferro-fluid and bodies submerged in it generates a so-called levitation force, which ensures that the bodies move in the required direction. This force usually acts against the direction of the gravitation force. The separation methods mentioned has been applied in the treatment of non-ferrous metal wastes, washability of coal, and mineralogical analyses.
- As wetting agents that are absorbed selectively to the surface of materials of interest and cause subsequent changes in their properties. The ferro-fluids adsorbed affect both the magnetic and surface properties of materials. The process of adsorption of ferro-fluids to the surface of solid materials is based on principles similar to those that apply to the adsorption of flotation agents.

Application fields of the technology: Recycling technologies, Mineral extraction

The research institute is looking for cooperation via joint venture agreement (the instutite is looking for a partner for this technological project) or via licence agreement (the Slovak institute is looking for licensees) especially with companies active in mining industry.
Advantages and Innovations:
- the magnetic properties of "carry" liquid can be improved easily
- another component of ferro-fluid, stabilising agent, prevents the colloidal particles from aggregation
- ferro-fluid is a special medium, and its production and density are adjustable under magnetic field.
- ferro-fluid could be easy applicable in recycling technologies or in mineral extraction
- application of ferro-fluids are especially in the treatment of primary and secondary raw materials
