Lake salt deposits may be classified into the following three types in terms of the mode of occurrence:
1) Solid-phase lake salt deposits.
They refer to the completely dried, brineless playas and the lake salt deposits dominated by solid Na-salt deposits. Solid lake-salt deposits are commonly exposed to the surface or buried at a shallow depth. The salt bodies occur in the stratified or stratoid forms, spreading over a large area, up to scores or hundreds of square kilometers with a thickness of several meters. The salt ores are dominated by halite in mine-ral composition and have a NaCl content exceeding 70% in most cases, and they usually contain various saline minerals such as mirabilite, gypsum, trona, sylvite, carnallite, magnesian salt and borates. The salt ores have a low hardness and are easily mineable. Solid-phase lake salt deposits are the principal targets of exploitation. They are represented by the Qarhan Silatu Lake in Qinghai, the Jarantai Salt Lake in Inner Mongolia, etc.As the professional manufacturer of complete sets of mining machinery, such as magnetic separator,spiral separator, Henan Hongxing is always doing the best in products and service.limestone rotary kiln:http://www.hxjq-crusher.com/23.html.ore separating line:http://www.hxjqchina.com/.
2) Liquid-phase lake salt deposits (otherwise termed brine salt lake deposits)
They refer to brine lakes without any sedimentary bed of halite or brine lakes with salt deposits below the indices of industrial exploitation. Brine salt lake deposits are rich in Na, K, Ca, Mg, B, Li, Br, I, Rb, Cs, Sr and other elements, but no large-scale development and utilization of such deposits have been carried out so far, except for the small-scale intermittent exploitation of only some individual brine lakes. Their representative deposits include the Ebinur Lake in Xinjiang and the Kunteyi Salt Lake in the Qaidam Basin of Qinghai.3) Mixed phase lake salt deposits with the solid and liquid phases in coexistence In salt deposits of this type solid-phase and liquid-phase salt bodies coexist and the solid salt and li-quid salt can be simultaneously mined. Such salt deposits are represented by the Eren Nur Salt Lake in Inner Mongolia and the Qijiaojing Salt Lake in Xinjiang.
