Jadarite


Jadarite is a white, earthy monoclinic silicate mineral, whose chemical formula is LiNaSiB3O7 or Na2OLi2O23H2O.

Discovery and classification

Jadarite was discovered in December 2004, in drill core from the Jadar Valley in Serbia, from which it is named. The find was located southwest of the Cer mountain. Findings were originally located in the villages of Jarebice and Slatina and later in Draginac.
Exploration geologists from Rio Tinto Exploration discovered the mineral as small rounded nodules in drill core, and were unable to match it with previously known minerals. Jadarite was confirmed as a new mineral after scientists at the Natural History Museum in London and the National Research Council of Canada conducted tests on it. Chris Stanley, from the Natural History Museum, described Jadarite as being unique to mineralogy.

Commercialization

The mineral discovery may be commercially important because the mineral contains lithium and boron, both relatively rare industrially important elements. Lithium is used for lithium batteries; boron is used in alloys, ceramic, glasses, and other applications.
It is estimated that there are 200 million tons of the lithium borate ore, which would make the future Jadar mines one of the world's largest lithium deposits, supplying 10% of the world's demand for lithium. Of that, the Lower Jadar ore deposit has 114.5 million tons with an average content of the profitable components of 1.8% of lithium oxide and 13.1% of boron oxide.
In May 2017, Rio Tinto announced that the Jadar area has one of the largest lithium deposits in the world, lifting Lower Jadar's deposits to 136 million tons. The company stated that the ore deposit's mineral resource estimation confirmed the quality of the mineral. Extraction is scheduled to begin in 2023, with a projected underground exploitability of 50 years.
, construction of a mine has not begun. A jadarite processing plant next to the mines, which will process the ore into lithium carbonate and boric acid, is also planned. The prototype facility has been constructed by the scientists from Serbia, Australia, and USA, and is being tested in Melbourne. Testing includes the processing of the jadarite concentrate.
On 25 July 2017 a memorandum was signed by Rio Tinto and the Government of Serbia, represented by the prime minister Ana Brnabić, which confirmed the year 2023 as the starting year, but also revealed that only now the working groups will be formed, studies will be conducted, and the process of issuing the permits will begin. The entire enterprise was named "Project Jadar".

Kryptonite

Jadarite's chemical formula is similar but not identical to the formula invented for the fictional substance kryptonite in the 2006 film Superman Returns. This coincidence attracted mass-media attention in 2007, shortly after jadarite's discovery..
The new mineral, unlike the fictional material in the movie, does not contain fluorine, and does not glow green.
