 (sĭl′vīt′) also syl·vine (-vēn′) or syl·vin·ite (-vĭ-nīt′)
A colorless vitreous potassium chloride mineral, the major ore of potassium.

[Alteration of sylvine, from French, from New Latin (sāl dīgestīvus) Sylviī, (digestive salt) of Sylvius, probably after Franz de la Boë, or Franciscus Sylvius (1614-1672), German-born Dutch physician.]

(Alliance News) - Kore Potash PLC said Monday it has received a proposal from a French consortium of engineering companies to reduce the capital cost of the Kola sylvinite deposit by USD415 million.
Kore has already indicated high-grade sylvinite intersections at Dougou and says that there is exploration potential across the area.
In the central basin, the A-l unit reaches sylvite saturation, and sylvinite deposits are found and have been economically exploited in the past.
In an area less than 50 km from Pamplona, Highfield Resources is planning to open the Muga mine, which will extract potash from sylvinite beds in an 80-[km.sup.2] deposit.
The Colluli Potash Project has a current JORC Compliant Measured, Indicated and Inferred Mineral Resource Estimate comprised of 133.70Mt @ 17.55% KCl of Measured Resources, 343.33Mt @ 17.38% KCl of Indicated Resources and 87.37Mt @ 24.96% KCl of Inferred Resources for a total of 564.40Mt @ 18.60% KCl (total contained potash of 104.96Mt); This includes higher grade Sylvinite of 130.39Mt @ 27.02% KCl.
Drilling will target Area 1 located approximately 30 kilometres to the south of Brazil's only operating potash mine, Vale's Taquari-Vassouras underground sylvinite mine.
At the Boulby mine, boracite occurs within massive sylvinite ore in a variety of habits ranging from isolated single crystals to large nodules.
However, this resulted in the intersection of a thick sylvinite section within the evaporite sequence, leading to further exploration and eventually to a significant mine being developed east of Sussex.
These are divided into 1.16 million [m.sup.2] for halite, 3.36 million [m.sup.2] for sylvinite (KCl plus NaCl), and 1 million [m.sup.2] for lithium.
The evaporite beds are mainly sylvinite (co-deposited sylvite and halite) with carnallite in places.
Kore undertook the scoping study at Dougou to consider the viability of producing 400,000 tonnes per year of potash from a portion of the sylvinite.
The 365km of Danakil property hosts three potash horizons, including sylvinite, carnallite and kainitite.
