The ore is composed predominantly by apatite (84% in weight basis) plus silicates (16%). In order to treat the ore from beds 1-5, a suitable standard mineral processing circuit (composed of scrubbing, screening, attrition and desliming) started its operation in 2010, yielding 3.9 Mt/y of concentrate assaying 30% of P2O5.
Apatite is the most common phosphate mineral, and is the main source of the phosphorus required by plants. The bones and teeth of most animals, including humans, are composed of calcium phosphate, which is the same material as Apatite. (These biological Apatites are almost exclusively the Hydroxylapatite type.) Chemical Formula.
In comparison with bone apatite, this suggests, at the first glance, that (CO 3) 2− groups are also incorporated in the plant apatite. However, the decoupling of the phosphorus and calcium concentration across the cell walls ( Fig. 3 ) rather implies the occurrence of a distinct amorphous carbonate phase together with nanocrystalline ...

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.
The paper studies the possibility of purification of process waters from apatite concentrate production from suspended particles and water-soluble impurities using polyacrylamide flocculants.
A new phosphate mine is being planned at Sokli in northern Finland. In the late 1970s, pilot-scale mining and mineral processing took place at the site.

The apatite-nepheline ore waste processing plant discussed in this paper is a complex chemical and energy technology system (CETS). It comprises three successively arranged process units: a granulator, a conveyor type multi-chamber calcining machine, (CTMCM), and an ore thermal furnace (OTF) [8]. The control of the CETS requires forming a complex
Performance management and reporting in chemical processing plants is essential to upper management in order to align employees, resources and systems to meet strategic objectives. However, the purpose of reporting overall equipment effectiveness (OEE) metrics is sometimes not viewed as particularly useful by plant operations teams.
A sample of apatite-bearing tailings was collected from the tailing dump of the Kovdor beneficiation plant in the Kola province of Russia. The sample was thoroughly mixed and homogenised to have a representative sample for chemical and particle size analyses, mineralogy characterisation, and flotation tests.
Poindexter Nut Company's commitment to continued improvement is demonstrated through our state-of-the art walnut processing plant. Equipped with the most advanced technology in the industry, the facility is processing over 50 million pounds per year and can be expanded to process up to 120 million pounds per year.
