Abstract

The method of separating grains of valuable minerals, precious metals, rare-earth metals, precious and semi-precious stones from natural ores in the aquatic environment by means of the phenomenon of adhesion, consecutively covering known stages such as: - initial separation consisting in sieving fractions up to 5000 µm from alluvial (rubble) ore or crushing primary (rock) ore to a fraction causing the separation of valuable minerals from gangue and where appropriate separating ferromagnetics from ores by means of a known method; - forming the suspension by mixing the initially separated fraction of ore with liquid; -adsorption of valuable minerals from the suspension on the adhesive coating and also recovering water from the process; - desorption of particles of valuable minerals from the adhesive coating according to the invention is characterised by the fact that for the formation of the adhesive coating in the separator, lanolin or its mixtures with additives are used, whereby, the content of lanolin in the mixture may not be less than 80%.

Claims (14)

Patent claims
1. A method of separating grains of precious metals, rare-earth metals, from natural ores in the aquatic environment by means of the phenomenon of adhesion, consecutively covering known stages such - initial separation consisting in sieving fractions up to 5000 pm from alluvial (rubble) ore or crushing primary (rock) ore to a fraction causing the separation of precious metals, rare earth metals from gangue and/or ferromagnetics by means of a known method; - forming a suspension by mixing the initially separated fraction of ore with liquid; - adsorption of precious metals, rare earth metals from the suspension on an adhesive coating and also recovering water; - desorption of particles of precious metals, rare earth metals from the adhesive coating; wherein liquid lanolin or its mixtures with additives are used to cover working surfaces of a separator with the adhesive coating, wherein, the content of lanolin in the mixture is not less than 80%.
2. The method according to claim 1, wherein beeswax is applied as an additive.
3. The method according to claim 1, wherein the adhesive coating containing 100% of lanolin is applied to the working surfaces of the separator after previously heating lanolin to a temperature from 36°C to 170°C and then after removing the excess of lanolin the separator is cooled down until the adhesive coating solidifies on the working surfaces of the separator.
4. The method according to claim 1 or 2, wherein the adhesive coating with liquid lanolin as a component of the mixtures with added beeswax is applied to the working surfaces of the separator after previously heating up the mixture to a temperature ensuring the melting of its components and then after removing the excess of the liquid mixture the separator is cooled down until the adhesive coating solidifies on the working surfaces of the separator.
5. The method according to claim 3 or 4, wherein the heated lanolin or its mixture is applied to the working surfaces of the separator by the flow of liquid lanolin or its mixture through the separator or by spraying working surfaces of the separator or by immersing the surface of the separator in liquid lanolin or its mixtures.
6. The method according to claim 1, wherein the adsorption process of precious metals, rare earth metals from suspension is conducted in a continuous manner by the flow of the suspension through the separator.
7. The method according to claim 1 or 6m wherein the suspension is saturated.
8. The method according to claim 1, wherein desorption is carried out at a temperature equal to or higher than the melting point of lanolin or its mixtures.
9. The method according to claims 1 or 8, wherein desorption is carried out with heated water.
10. The method according to claim 1 or 8, wherein desorption is carried out using another heated solvent selected to the composition of the mixture, causing dissolution and outflow of the adhesive coating from the separator together with precious metals, rare earth metals.
11. The method according to claim 1 or 8, wherein desorption is carried out using a gaseous medium heated to a temperature causing the adhesive surface to melt.
12. The method according to claim 1 or any one of claims 8 to 11, wherein desorption is carried out in a separator equipped with its own heating system.
13. The method according to claim 1, wherein during the desorption process precious metals, rare earth metals from the dissolved adhesive coating are separated in a sedimentation tank in the presence of liquid with a specific gravity higher than the specific gravity of lanolin or its mixtures.
14. The method according to claim 1, wherein lanolin or its mixtures recovered in the separation process is directed for reuse in the process.
