As will be discussed, once a mineral concentrate is produced, the contained rare earth value can be large compared with transportation costs, and the sections of the value chain dealing with chemical extraction (the largest cost) and separation into individual rare earth compounds can be remotely located.

(2) A reasonable process for narrow-level selection is realized. In the process of mineral separation, the degree of separation of minerals is not only related to the characteristics of the mineral itself, but also to the specific surface area of the mineral particles. This effect is more prominent in the flotation process.

Mineral and salts are absorbed by a process called diffusion. Diffusion is the movement of solute molecules of a solid, a gas or liquid from a region of high concentration region to that of low concentration region. Difference Between Osmosis and Diffusion: In osmosis, solvent moves from lower concentration region to higher concentration region.
