Management experience and operation practice on earlier production stage in the salt field of 200,000 t/a in Guotou Luobupo Potash Salt Co.,Ltd.;

Through solar evaporation in 400 m~2 salt field in winter in Zabuye Salt Lake,the rule of composition evoltion of the brine is studied,and we explore and summarize the salt field operating situation and practical result of brine-preparation in winter.

When the solution obtained by leaching of natural sodium nitrate ores in Xinjiang Lop Nur, is evaporated in the sunning process, NaCl and Na2SO4 are crystallized and separated, and the recovery ratio of NaNO3 is greatly effected by the number of solar ponds and the concentration distribution in these solar ponds.

In Chaerhan Salt Lake, solar ponds production is the entrance of "life" of potassium products.

New method with soft permeable materials for brine pan slope protection;

Collecting water and soil samples from Tainan brine pan of Lianyungang, taking salt(NaCl) as the sole growth limiting factor, we have investigated the numerical distribution of halophilic bacteria with the media containing 4%, 12% and 25% mass-concentration of NaCl.

Upon the complexity of the technology calculation of salt pan and the application tendency of computer software,and taking the modularization designing idea as the direction,utilizing Visual Basic 6.

For the comprehensive utilization of saline soils in the salt pan and based on the introduction to its biological characteristics,the economic uses of Salicornia bigelovii,one of the seawater-irrigated crops,were reviewed in detail.

Application of seepage control membrane in construction of isolated solar pond

Based on generous sampling and analyzing data on solar ponds of Qinghai Salt Lake Industry Group Co.

According to the isotemperature- evaporation-test data of solar ponds brine in Chaerhan salt lake, this paper discusses the methods that using regression analysis creates production and management models of solar ponds, and describes its operation.
