Refined table salt is made by rock salt which formed hundreds of millions of years ago, natural, non- pollution and healthy. It is produced by the most advanced refined vacuum process, each producing step is strictly controled, which guarrantees the good quality, meet food grade. As a kind of edible salt, it is totally safe for cooking or food processing industry. We offer a wide variety of salt products, such as refined salt, table salt iodized or non-iodized, low sodium salt, industrial salt, sea salt and so on.

1. Nacl of rock salt is 5~9% higher than Nacl of sea salt . The rock salt can be more than 99% while 92-95% for sea salt .
2.Impurity substance of rock salt is less than sea salt. The main impurity substance of sea salt of is Ca, Mg, Fe(CN)6 and silt. But there can be no impurity substance of Ca,Mg and lower 0.2% of Fe(CN)6 for purification technology produced rock salt.
3.For two alkali industry, it can cut the cost with using well rock salt instead of using sea salt. Especially for impurity removal cost . Meanwhile it also can cut cost of slit removal. The shortcoming for using sea salt is big grain,need crush,too much impurity substance,high sewage cost ,low quality and too complicated impurity removal.
4.The rock salt is natural. The material almost not be destroyed as it is vacuum salt production . The seawater ,which is raw material of sea salt , is polluted by harmful chemicals and this phenomenon become more and more serious with development of modern technology. While the raw material of well rock salt not be polluted at all .
