  • 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
    Patent number: 11623225
    Abstract: A 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 stages such as: initial separation consisting in sieving fractions up to 5000 ?m 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; and desorption of particles of valuable minerals from the adhesive coating; wherein lanolin or its mixtures with additives are used to form the adhesive coating in the separator, whereby, the content of lanolin in the mixture is not less than 80%.
