The process has been developed for processing apatite from LKAB's mine waste. The process can handle both types of apatite produced by LKAB in Kiruna and Malmberget and, in addition to phosphorus, it can extract rare earth metals. The process separates the arsenic and fluoride contained in the apatite; i.e., theses substances do not end up in ...
The word apatite is derived from the Greek word for deceit, "apate" because apatite can be mistaken for many other minerals. It is usually green, but can also be blue, yellow, purple, or brown. Apatite is the main source of phosphorous, an important nutrient required by plants. As such, apatite is the key ingredient in phosphate fertilizers.
Further processing will be done using chemical processing, and LKAB is currently developing the method. "We estimate that a full-scale production from Malmberget and Kiruna will produce around 400,000 tonnes of apatite concentrate annually, in two plants that will be of similar size to our existing iron ore concentrating plants.

These plants are part of a prefeasibility study to define a commercial mine waste recycling process, ReeMAP, LKAB President and Group CEO Jan Moström said. The company has made this decision after laboratory tests during 2018 confirmed it could produce more phosphorus and rare earth metals than previously estimated.

There have been many studies investigating processing of apatite, investigations into reagents used in flotation such as oleic acid and sodium oleate [17,52]. Froth flotation of apatite is one of the main methods of mining the mineral from host ores . Selecting the correct reagents is important in optimizing the process.
It is found that it is efficient to stabilize the processing feed through preconcentration of apatite ore by means of coarse X-ray luminescence separation that elevates P 2 O 5 content of process flow owing to removal to 20% of material with P 2 O 5 content to 2%. The semi-commercial tests reveal destabilizing factors which lower the separation ...
