    With rare earth elements, the time between a mining company's decision to acquire a property and the start of production can be several years or longer There is no fast way to open a new mining property If a single country controls almost all of the production and makes a firm decision not to export, then the entire supply of a commodity can be quickly cut off That is a dangerous situation .Sweden has been called the "home of the rare earth elements", due to the fact that both the first light and the first heavy rare earth elements (LREE and HREE, respectively) were discovered here during the late 18th and early 19th centuri.
