Based on the flotation test on raw rare earth ores in Bayan Obo Ore for mineral processing, it was found that the activation of apatite by polyacrylamide (PAM) flocculant [11], [12] used in beneficiation backwater in the flotation of rare earth ores mainly contributes to the high phosphorus content in 58% rare earth concentrate.

Apatite (Ca 5 (PO 4) 3 (OH,F,Cl)) is an ubiquitous accessory phosphate mineral found in many types of rocks and environments. This is particularly true with regards to ore deposits. This mineral has several key characteristics that are very useful when one is interested in the characterization and/or the dating of the circulations of fluid (s ...

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.

As said before, in the industrial flotation of phosphate ore, a selectivity ratio of about 4.0 between apatite and iron minerals and of 10 between apatite and silicate minerals are considered satisfactory. Additional requirements are a phosphorus grade of about 28–30% and an apatite recovery rate of more than 40%.

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.

Producers leave $1,500 to $2,000 "on the table" for every steer they sell, and wait times to get into a processing facility can be one to two years, he said. The facility in Havre is near the end of construction and will open soon. The plant is expected to be a year-round operation that can process cattle, hogs, sheep and bison.

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.

About Apatite II. Phosphate-Induced Metal Stabilization (PIMS) is a technology that uses a special material, Apatite II, to clean-up soil and groundwater contaminated with metals. PIMS stabilizes a wide range of metals, especially lead (Pb), uranium (U), plutonium (Pu), zinc (Zn) and cadmium (Cd), either in place or after removal from the ground.
