At present, the price of ferrous sulfate on the market varies from 160 to 500 yuan / ton according to its content. Among them, the drying type ferrous sulfate after drying and purification ranges from 550 to 850 yuan / ton, and the price of raw material grade ferrous sulfate monohydrate is more expensive. So what are the factors that affect the market price of ferrous sulfate?

For the price fluctuation of ferrous sulfate and other chemical products, the price fluctuation is mainly caused by the production cost and freight cost. The main production methods of ferrous sulfate are: titanium dioxide by-product, iron filings / hydrochloric acid reaction method, copper sulfate solution reaction method. At present, a widely used and low-cost production method is titanium dioxide by-product preparation. However, the main raw material for the preparation of ferrous sulfate by titanium dioxide by-product method is ferrous sulfate produced during the decomposition of ilmenite by sulfuric acid. So sulfuric acid is the main cost of ferrous sulfate. So the price fluctuation of sulfuric acid leads to its price fluctuation. Assuming that the ex factory price of industrial sulfuric acid has increased from 190 yuan / ton to 380 yuan / ton in the past six months, the production cost of ferrous sulfate will increase by 58.3 yuan / ton (324 kg 98% industrial sulfuric acid will be consumed for the production of ferrous sulfate per ton). This leads to the rise of ferrous sulfate price.

In addition, because ferrous sulfate is a low-cost chemical, its freight is the most important factor in its price. Once the national transportation department strictly controls the road transportation, or because some transportation hubs hold major events or exhibitions, the national short-term strict control will lead to a substantial increase in the freight of transportation goods and the cost of ferrous sulfate.

In addition to the cost of raw materials and freight, ferrous sulfate is also affected by market factors. As the application field of ferrous sulfate is more and more extensive, it can be used as flocculant for water treatment, soil conditioner, cement additive, battery catalyst, drying agent, etc., which makes the market more and more in short supply. This is also an important factor for the rising market price of ferrous sulfate in recent years.

Generally, if the company has a certain production scale, the price of ferrous sulfate heptahydrate with stable content of 90% is usually about 200 yuan / ton, and the price of drying ferrous sulfate with stable content of 98% is about 600 yuan. The larger the quantity, the lower the cost and the lower the price.
