Alvaro Alonso Barba facts for kids

Alvaro Alonso Barba was a Catholic priest and a very clever scientist who studied metals. He was born in Lepe, a town in Spain, in 1569.

He is thought to have come from the Andalusia region of Spain. Father Barba lived in a place called Potosí (which is now in Bolivia) when its silver mines were producing a huge amount of silver. During this time, many Spanish residents and mine owners in Potosí were very wealthy.

A Priest and a Scientist

Father Barba spent his time doing his duties as a priest and also carefully studying the rocks and ores from the Potosí region. He also learned about how to process these ores. Around 1570, there was a big change in how silver was taken out of ore. This was done by using a liquid metal called mercury. Father Barba knew about these new methods and helped to improve them.

His Big Invention

In 1609, Alvaro Alonso Barba invented a special way to get silver from ore. This method is called the pan amalgamation process. In this process, he mixed the silver ore with salt and mercury. Then, he heated this mixture in shallow copper pots. This heating helped to separate the silver from the other materials.

In 1640, he published an important book in Madrid, Spain. The book was called Arte de los Metales, which means "The Art of Metals." This was the very first book about ores and minerals found in South America. It even included information about where to find minerals in Bolivia. His book has been translated and published in many languages, including Spanish, French, English, and German.
