Recently, part of the raw salt market in Shandong has risen. The local supply is mainly divided into sea salt and well mineral salt, and the market supply and demand is active. Raw salt is mainly used in two alkali industries, and some small industrial salts are sent to printing and dyeing, medicine, water purification, food processing and other industries. At present, the shipment of sea salt market is stable on demand. The power and production of well and mineral salt are limited, and the factory inventory is tight. With the continuous high coal price, the cost of well mineral salt continued to rise, and the reduced sales of sea salt, the price of some mineral salt factories increased by 20-30 yuan / ton.
