The term "earth" is an old chemical term for oxides, i.e. compounds containing oxygen. The chemically-similar elements of the third group of the periodic system (with the exception of actinium) and lanthanides are considered rare earths.

Waste streams from REE processing have been identified, and their hazardous waste potential assessed. Although potentially significant, based on case studies and chemical composition,

After high energy mechanical milling of the CuSn/TiH 2 powders, rare earth Ce was added into the milled powders to improve the materials’ properties. The addition of rare earth Ce was 0.25 wt %, 0.50 wt %, 0.75 wt % and 1.0 wt %, respectively. The mixed powders were blended together for 1 h to make rare earth Ce to be evenly distributed. After the preparation of Cu-based alloy

28/03/2011· IRC’s main objectives were to improve upon the historical method of creating rare earth oxide (REO) concentrates from Kutessay II in four main areas – decreasing the costs associated with the historical milling process; recovering additional polymetalic byproducts; increasing the total REO (TREO) content within the concentrate significantly above the
