Abstract

The invention provides a method for extracting rubidium from rubidium-containing ore through ultrasonic strengthening. The method comprises the following steps: placing the rubidium-containing ore in an ore grinding machine for ore grinding, and taking the obtained ore powder as an experimental raw material; putting a material obtained by fully mixing calcium chloride and ore powder into an alumina crucible, roasting at the temperature of 700-900 DEG C, preserving heat for 15-35 minutes, cooling to room temperature after reaction, grinding the reacted material into powder by using an ore grinding machine to serve as a leaching raw material, putting the roasted material into water, performing low-temperature ultrasonic enhanced leaching at the leaching temperature of 30-50 DEG C for 15-35 minutes, and obtaining leaching liquid and leaching residues. Under a low-temperature system, high leaching rate and leaching speed can be realized, the method has the advantages of energy conservation, rapidness and high efficiency, the extraction time of the rubidium extraction process is remarkably shortened, the process conditions are improved and simplified, the rubidium element is efficiently extracted under the low-temperature or normal-temperature energy-saving condition, and the leaching effect can reach 98% or above.

Description

technical field [0001] The invention relates to the technical field of mineral extraction, in particular to a method for ultrasonically enhancing the extraction of rubidium from rubidium-containing ores. Background technique [0002] Rubidium is a very important rare metal that occupies an important position in the national economy. Due to its unique properties, it has been widely used in many fields, especially in high-end technology fields. In traditional fields, rubidium is mostly used in electronic devices, biological materials, and catalysts. In recent years, it has been gradually discovered that it also has great development potential in high-end fields such as energy, magnetic fluid power generation, and rubidium atomic clocks. It can be seen from this that with the continuous development of science and technology, the demand for rubidium will gradually increase. [0003] At present, the content of rubidium in the earth's crust is 0.028%, which mainly exists in lithi...
