Prospection for REE and Y is largely connected to that of other metals, together with which REE are found in nature. However, a few dominantly REE deposits are also known. One of the major difficulties is the recognition of REE minerals in the field, since many REE (Y) ores are composed of rare exotic minerals not always known to prospectors.
Read MoreProspecting For Rare Earth Elements has proven to be more challenging than conventional Gold or base metal prospecting. One of the primary reasons being is Field Identification. Rare earth elements typically form exotic minerals which are either confused with other minerals or
Read More2014-10-7 Prospecting techniques for the rare earth element (REE) resources in the past were mainly geochemical prospecting of surface samples, collected along grids or lines, followed by laboratory analysis using X-ray fluorescence (XRF) and inductively coupled plasma-mass spectrometry (ICP-MS).

Read MoreRare earth elements (REEs) represent the group of 17 elements comprising 15 lanthanides, plus yttrium (Y) and scandium (Sc) (Table 1). Among the REEs, yttrium was discovered first in 1794 by a Finish chemist, Johan Gadolin who isolated an oxide and called it “yttria,” in a mineral collected from a quarry near the village of Ytterby in Sweden.
