Apatite has been used in the production of fertilizers for several decades. To obtain fer-tilizers, apatite is leached by acids such as sulphuric, nitric, or hydrochloric. The resulting solutions of phosphoric acid, which are used in the further process without rare-earth ele-ments extraction, contain up to 0.1% of REE.
Maine Feldspar Quarry, East Mount Apatite Mining District, …
The Maine Feldspar Co. leased the area in 1902 which resulted in the largest commercial mining excavation at Mount Apatite. Feldspar was mined chiefly for the china and porcelain industry and was first transported to Topsham and later two miles south to their processing plant, established in 1906, at Littlefield Station.

A roast–leach process has been reported for the extraction of rare earth from complex monazite concentrates using sulfuric acid and other leaching agents at the Pea Ridge iron mine in Sullivan (Franken, 1995). In this process, the RE phosphate of the ore is converted to its oxide, which eliminated hazardous processing steps currently in practice.
