Geology and Mineral Resources - Rare Earth Elements - ia
Rare earth elements (REE) include the 15 lanthanide elements on the periodic table from lanthanum (La) to lutetium (Lu), and also properly include the transition metals scandium (Sc) and yttrium (Y). The REE are classified as metals and are relatively soft, ductile and malleable. Most have a silver-gray luster and oxidize rapidly in air to form ...

Ilmenite - an overview | ScienceDirect Topics
Ilmenite, FeTiO 3 is used in the manufacture of TiCl 4, and subsequent production of TiO 2, mostly for pigment applications. This mineral is mined as mineral sands or hard rock deposits. To separate the iron from the titanium compound strong hydrochloric acid is used, generating iron chloride solutions.

What is hardrock mining? – Short-Facts
What was the difference between Placer mining and hard rock mining? Generally as the placers would slowly become exhausted, miners would begin tracing the source of the gold and begin developing hard rock mines. These mines were more labor-intensive than placer mining, but if a rich gold vein was located they could be exceptionally rich to work.
