In these cases, halite is said to be behaving like a rheid. Unusual, purple, fibrous vein-filling halite is found in France and a few other localities. Halite crystals termed hopper crystals appear to be "skeletons" of the typical cubes, with the edges present and stairstep depressions on, or rather in, each crystal face. In a rapidly ...
Two commercially important halide minerals are halite and fluorite. The former is a major source of sodium chloride, in parallel with sodium chloride extracted from sea water or brine wells. Fluorite is a major source of hydrogen fluoride, complementing the supply obtained as a byproduct of the production of fertilizer. Carnallite and ...
Diorama of an underground salt mine in Germany. Inside Salina Veche, in Slănic, Prahova, Romania.The railing (lower middle) gives the viewer an idea of scale. Before the advent of the modern internal combustion engine and earth-moving equipment, mining salt was one of the most expensive and dangerous of operations because of rapid dehydration caused by constant contact with the salt (both in ...

A cobble encrusted with halite evaporated from the Dead Sea, Israel (with Israeli ₪1 coin [diameter 18mm] for scale). An evaporite (/ ɪ ˈ v æ p ə ˌ r aɪ t /) is a water-soluble sedimentary mineral deposit that results from concentration and crystallization by evaporation from an aqueous solution. [1]
This mineral is typically mined in placer deposits, with gold commonly found as a byproduct. [25] The rare earth element neodymium is found in monazite, making it a rare mineral. [ 25 ] Moreover, monazite contains many other rare metals such as cerium , lanthanum , praseodymium , and samarium, making it a critical source of renewable energy. [ 26 ]
Halite is the mineral form of sodium chloride. Halite may also refer to: Halite (oxyanion), also known as a halogenite; Central Sofia Market Hall, in Sofia, Bulgaria
Carnallite is an uncommon double chloride mineral that only forms under specific environmental conditions in an evaporating sea or sedimentary basin. It is mined for both potassium and magnesium and occurs in the evaporite deposits of Carlsbad, New Mexico ; the Paradox Basin in Colorado and Utah ; Stassfurt , Germany ; the Perm Basin , Russia ...
