Title: Marika Tiihonen: Innovator in Lithium Extraction Technologies
Introduction
Marika Tiihonen is a prominent inventor based in Espoo, Finland. She has made significant contributions to the field of lithium extraction, holding a total of 5 patents. Her innovative methods focus on improving the efficiency and effectiveness of lithium recovery from mineral sources.
Latest Patents
Tiihonen's latest patents include a method of extracting lithium compounds and a method for recovering lithium hydroxide. The first patent describes a comprehensive process that involves leaching lithium-containing minerals in an aqueous solution with alkaline carbonate. This process liberates lithium and phosphates, resulting in a leach slurry. The subsequent carbonization step reacts the leach slurry with an alkali earth metal compound, leading to the formation of lithium hydrogen carbonate and the precipitation of insoluble phosphate compounds. Finally, a solid-liquid separation step is employed to recover the lithium hydrogen carbonate solution.
The second patent outlines a method for recovering lithium hydroxide from lithium-containing minerals. This process involves pulping the raw material with water and an alkali metal carbonate, followed by a two-step leaching process. The resulting slurry is separated into solids and a solution containing lithium hydroxide, which is then purified. Lithium hydroxide monohydrate can be crystallized from the purified solution, and the process allows for recycling of the solution back into earlier steps.
Career Highlights
Throughout her career, Marika Tiihonen has worked with notable companies such as Outotec (Finland) Oy and Outotec Oyj. Her work has focused on advancing technologies related to mineral processing and lithium extraction, contributing to the growing demand for sustainable lithium sources.
