Embodiment Construction

[0036] Example I:

[0037] In the example of alluvial deposits located in Bulgaria, a method for separating particles of valuable minerals, precious metals, rare earth metals, precious and semi-precious stones from natural ores in an aqueous environment by adhesion phenomena in amounts of A ton of ore is about 2 grams of gold, in which the gold particles oscillate between a few micrometers and a few millimeters.

[0038] A portion of particles smaller than 3 mm was washed from the 100 kg of ore used for the test on the sieve. This fraction is magnetically separated in separator 2 to remove ferromagnetic particles. In other embodiments, the magnetic separation process may be omitted if the deposit does not contain ferromagnetic particles.

[0039] Subsequently, this purified ore portion is placed in pool 3, into which water from pool 4 is poured. In this way, 150 liters of suspension are formed in the tank 3 containing about 50 kg of an ore fraction with a particle size of l...

Abstract

Process for separating particles of valuable minerals, precious metals, rare earth metals, gemstones and sub-gemstones from natural ores by adhesion phenomena in an aqueous environment, consecutively encompassing a number of known stages, such as:-a preliminary separation; comprising screening up to 5000 [mu] m fractions from alluvial (macadam) ore or crushing native (rock) ore into fractions such that valuable minerals are separated from gangue and, if appropriate, ferromagnets are separated from the ore by known methods; forming a suspension by mixing the preliminarily separated ore fraction with a liquid; -adsorption of valuable minerals from the suspension on the binder coating and also recovery of water from the process; -desorbing particles of valuable minerals from the binder coating according to the invention, characterized in that lanolin or a mixture thereof with additives is used to form the binder coating in the separator, the content of lanolin in the mixture may be no less than 80%.

Description

technical field [0001] The subject of the present invention is the separation of valuable minerals (valuable minerals, valuable minerals), precious metals, rare earth metals, precious stones and sub-precious stones (semi-precious stones, secondary precious stones, semi-precious stones) in the form of particles. The method is suitable for recovering particles of valuable minerals from 1 to 5000 μm, where the term "valuable minerals" implies precious metals, rare earth metals, precious and sub-precious stones. The invention is particularly suitable for the separation of gold, but this does not limit its scope of application. Background technique [0002] The global mining industry accepts methods for recovering gold from ore, based on: [0003] - Chemical methods (approximately 80% of the world market), exploiting the phenomenon of digestion of precious metals in strong compounds. Cyanide and mercury are mainly used in these methods. These methods are highly efficient in t...
