Lithium sulfate

Great Salt Lake, Utah, is the largest terminal lake in the United States. From its brine, salt, elemental magnesium, magnesium chloride, sodium sulfate, and potassium sulfate ate produced. Other well-known terminal lakes ate Qinghai Lake in China, Tu2 Golu in Turkey, the Caspian Sea and Atal skoje in the states of the former Soviet Union, and Urmia in Iran. There ate thousands of small terminal lakes spread across most countries of the world. Most of these lakes contain sodium chloride, but many contain ions of magnesium, calcium, potassium, boron, lithium, sulfates, carbonates, and nitrates. 

Lithium is extracted from the ores lepidolite and spodumene, which contain up to 8% lithium oxide. The ore is converted first to lithium sulfate by acid roasting at 250°C and then to lithium chloride via the carbonate. Electrolysis of the fused...

When lithium sulfate, Li2S04, is dissolved in water, the temperature increases. Which of the following conclusions may be related to this ... 

Experiments were performed with various LiAl-X LDHs, with X = Br, NO3 and ISO4. As with the intercalation process, the nature of the anion exerts a powerful influence on the reaction. In the case of sulfate, the deintercalation reaction does not go to completion - only 40% of the available lithium sulfate was released. The deintercalation reaction initially proceeds very quickly, but the process is then halted. The rate of deintercalation is NOs" > Cl > Br . This series does not correspond with data on the anion selectivity for intercalation into Al(OH)3, which is S04 > Cl" > Br" > NO3". Neither is there a correlation of the release data with the heats of hydration of the anions. The series observed arises because the intercalation and deintercalation processes are a balance of a number of factors, including interactions between the guest ions and the host matrix.

Alternatively, limestone may be used instead of sulfuric acid to recover lithium from spodumene. Such recovery processes, known as alkaline methods, involve heating the ore with a mixture of ground limestone and calcium sulfate or chloride to form lithium sulfate or chloride. Leaching the kiln discharge with water yields an aqueous solution of hthium sulfate or chloride. 

Lithium sulfate is used in making a special type of high strength glass. It also is used in medicine as an antidepressant. 

Lithium sulfate is prepared by neutralization of lithium hydroxide or hthi-um carbonate with sulfuric acid followed by crystallization ... 

The tantalates are produced by a solid-state reaction between Ta205, Nb205, and Y203 in a 14-hour preliminary firing at 1000°C and a crystallization firing with lithium chloride or lithium sulfate as flux.
