Rare earth elements are separated into two categories light rare earths and heavy rare earths The light rare earth elements are lanthanum cerium praseodymium neodymium and samarium and they are more abundant than heavy ones The heavy rare earth elements are not as predominant as light rare earths and are generally
Since the size of powders several µm is too small for the application of conventional separation technologies froth flotation two liquid flotation is a unique pathway for the material recycling of ultra fine rare earth fluorescent powders
The possibility of flotation extraction of lanthanum and cerium III compounds from diluted sulfate solutions was shown by using finely dispersed solid solutions of different radical phosphine oxide in paraffin Optimal conditions for conducting the flotation have been determined The effect of
But China has not always wielded a monopoly over rare earth production From the 1960s to the 1980s a Mojave Desert mine in California was the world s largest supplier of rare earths During the 1990s however China s entrance into the world market lowered global prices at the same time the Mojave mine experienced expensive pipeline
