Production and

Extraction of Europium

Europium is a rare earth element found in trace amounts in the earths crust. Its production and extraction are limited to a few regions worldwide.

In this article, we will explore the sources of europium, and the extraction and production processes involved in obtaining the element.

Sources

Europium is present in a wide range of minerals and rocks, including monazite, xenotime, and bastnasite. Monazite is the primary source of europium, and it contains about 0.05% of europium oxide.

Xenotime is a relatively rare mineral that contains about 0.02% of europium oxide. Bastnasite, on the other hand, contains about 0.26% of europium oxide.

Europium can also be extracted from ion adsorption clays found in southern China, which are a mixture of clays and weathered soil. These clays have a high concentration of rare earth elements, including europium, which can be extracted using solvent extraction, ion exchange, and precipitation methods.

Extraction

The extraction of europium is a complex process that involves several stages. The first step involves extracting the rare earth elements from the ores using methods such as solvent extraction, ion exchange, and precipitation.

The obtained rare earth oxide is then reduced to obtain the metal europium, which is finally purified and distilled. Solvent extraction is one of the most common methods for extracting rare earth elements from the ores.

This process involves adding a solvent to the ore mixture, which selectively extracts the rare earth elements. The solvent is then separated from the ore mixture, leaving behind the rare earth elements.

Ion-exchange is another method used to extract the rare earth elements from the ores. In this method, the rare earth elements are selectively adsorbed by ion-exchange resins under specific pH and temperature conditions.

The impurities are then removed, leaving behind the rare earth elements. Precipitation is another method used to extract europium from rare earth ores.

In this method, the rare earth elements are precipitated as hydroxides or oxalates, leaving behind impurities. The precipitate is then dissolved, and the europium isolated using a series of distillation and reduction steps.

Production

The production of europium is a two-step process. The first step involves the production of europium oxide, which is then reduced to obtain the metal europium.

Europium oxide is obtained from the ores using purification methods such as electrolysis, reduction, distillation, and zone melting. Electrolysis involves passing an electric current through a molten salt containing europium oxide, which produces a pure form of europium.

Reduction involves mixing europium oxide with a reducing agent such as calcium, which reduces the europium oxide to europium metal. Distillation involves evaporating the europium oxide to obtain pure europium, while zone melting involves the process of melting the europium oxide, which is then separated into pure europium using a series of melting and solidification steps.

History of Europium

Discovery

Europium was discovered in 1890 by French chemist Paul mile Lecoq de Boisbaudran. Lecoq used atomic spectroscopy to isolate europium from an impure sample of samarium oxide.

He named the new element europium after Europe, his homeland.

Naming

Europium’s discovery was significant since it was only the second rare earth element discovered after yttrium. The new element was initially mistaken for gadolinium, another rare earth element.

Lecoq discovered that europium was different from other rare earth elements when he observed its unique red luminescence properties.

Early Uses

Europium’s unique luminescence properties made it valuable in early applications such as phosphorescent powders and color television screens. Europium was also utilized in fluorescent lights, x-ray intensifying screens, and as a neutron absorber in nuclear reactors.
