The platinum metals

"The Platinum Metals" by Arthur Douglas Lumb is a scientific account that explores the origins, traits, and functions of platinum group metals. This study examines how to extract these elements along with their importance, particularly for the British Empire. The text looks to explain where these metals come from and how they're used as platinum became more crucial after World War I. The series starts by introducing the platinum group metals and pointing out where they can be found along with how they are developed. The narrative also talks through the change in how these materials were obtained when the war disrupted the market, including resources from Russia and Colombia. It sets the stage for a further look at how these materials are taken out, cleaned, and how they are being used more in factory settings.
