PROCESSING OF SYLVINITE ORES AND ITS PHYSICAL AND …
For flotation sylvinite, it is neecssary to grind the ore to the size of 1-2 mm to 3 mm as much as possible, and more fineness will lead to the loss of a part of the product mixed with the slag during flotation and the deterioration of the product quality. But in this case, the level of NaCl in the sylvin sample should exceed 85-90% as much as possible.

But it is unfortunate that the Br×103/Cl ratio, as a common geochemical index to uncover clues of sylvinite deposit, is almost invalid to indicate the stage of ancient brine condensation for very low content of bromine in salt rock samples (less than 10−6 commonly) in the western Tarim Basin evaporites. Fortunately, we noticed recently that ...

Carnallite-Sylvite Relationships in the Middle Devonian …
Sylvinite overlies carnallitite, the reverse of a normal depositional sequence. The distribution of traces of bromide and rubidium in the chloride minerals indicates that red sylvinite was formed by leaching of magnesium chloride from carnallitite. This conclusion is substantiated by textural observations at carnallite-sylvite contacts, where ...

Potash occurs in the deep, center of the Michigan basin and contained exclusively in the Salina A-1 Evaporite formation as Sylvinite in the middle or upper portions of the formation. The Potash occurs as Sylvite (in relatively pure beds as much as 30 feet thick or as Sylvite (KCl) intimately intermixed with Halite (NaCl) as Sylvinite.

Sylvinite slurry, not carnallitite, is the precipitated salt in the harvest pond at Wendover (Bingham 1980). But the concentration process does not end with sylvite precipitation. Brine is pumped out of the sylvinite harvest pond into the adjacent carnallite ponds before the brine density attains values in excess of 1.257. This is the density ...
