Process for the Production of a Rubidium- and Lithium-Containing Aqueous Solution from Rubidium- and Lithium-Containing Minerals

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention describes a process for extracting lithium and rubidium from minerals containing these elements. The process involves crushing and tempering the minerals, creating a water-based suspension with alkali carbonate, and reacting the mixture under pressure with CO2. This results in the formation of lithium and rubidium carbonates or their hydrogencarbonates, with extraction rates for both elements exceeding 70%.

Use CasesContent extracted from patent full text and abstract with AI.

• Production of lithium and rubidium chemicals for use in batteries and electronics
• Extraction of lithium and rubidium from mineral ores in mining industries
• Supply of high-purity lithium and rubidium solutions for chemical manufacturing
• Efficient resource utilization in mineral processing plants

BenefitsContent extracted from patent full text and abstract with AI.

• Achieves high extraction efficiency (>70%) for both lithium and rubidium
• Enables recovery of two valuable elements in one step
• Increases the commercial value of mineral resources that contain both lithium and rubidium
• Potentially reduces processing costs compared to traditional extraction methods
• Supports growing demand for lithium (batteries) and rubidium (electronics, specialty chemicals)
