Dead Sea Works Process. The Dead Sea Works, a subsidiary of Israel Chemicals Ltd., aimounced plans ia 1992 to constmct a 25,000 t/yr magnesium plant at Beer-Sheva, Israel. The plant, to be based on Russian camaHite technology, is designed to use an existing potash plant as the source of camaHte. The chlorine by-product can be either Hquefted and sold, or used ia an existing bromine plant. Waste streams from the camaHite process, as well as spent electrolyte from the electrolytic cells, can be returned to the potash plant. [Pg.319]

During this time, other materials that gave rubberlike materials were found. In 1901, I. Kondakov, a Russian, discovered that dimethyl butadiene when heated with potash formed a rubberlike material. In 1910, S.V. Lebedev, another Russian, reacted butadiene forming a rubberlike material (structure 9.33). [Pg.285]

Gallium, Mendeleev s eka-aluminum, was discovered by Paul Emile Lecoq de Boisbaudran in 1875,5 years after the Russian chemist left a blank in his table for it and predicted a number of its properties. De Boisbaudran identified the element in a sample of zinc ore by using the still-new field of spectroscopy that Bunsen and Kirchhoff had employed to detect the fingerprints of elements such as cesium and rubidium (see p. 325). Within a month he had completed a series of conversions ending in the electrolysis of an aqueous solution of the hydroxide and potash (potassium carbonate). He isolated enough of the easily liquefied metal (mp = 29.78° C) to measure its properties and even present some to the French Academy of Sciences. A comparison of the properties of gallium and those predicted for eka-aluminum is given in Table 14.1. [Pg.380]

The former Russian states have a large number of potash and halite deposits (Fig. 2.9), and calcium chloride brines have been associated with many of them. Sturua (1974) has presented a map of various Russian calcium chloride groundwater occurrences, and the majority of them are closely grouped near major potash deposits. In the Caspian Depression, Moskovskiy and Anisimov (1991) have reported such brines, and the Carpathian group s Stebnik potash deposit in south-central Russia (which contains potassium sulfate minerals, and not the normal sylvinite), still has dolomitization brine near the deposit (Valyashko et al, 1973). Similar brines have been found with 80-169 g/liter Ca in the Ukraine s Dnieper-Donets Basin, grading to 50, then 6 and finally 1.5 g/liter CaCl2 as the... [Pg.258]
