Ferrous Sulfate Classification | Types, Grades, Uses

    1. By application: Ferrous sulfate, a compound of sulfuric acid and iron, is a trace element of iron, widely used in:
      • human food
      • animal feed
      • construction materials
      • agriculture / fertilizer
      • water treatment
      • battery / electronics

According to its application, bulk ferrous sulfate has industrial grade, agricultural grade, feed grade, pharmaceutical grade, food grade, and reagent grade. Hippocampus OU supplies high-quality ferrous sulfate industrial grade (contains ferrous sulfate Water treatment grade), ferrous sulfate feed grade, ferrous sulfate fertilizer grade.

      1. By number of water molecules in ferrous sulfate formula: With strong reducibility, ferrous sulfate is easily oxidized into brown iron sulfate in the air. When we say ferrous sulfate, we mean ferrous sulfate that contains water of crystallization. Ferrous sulfate is classified into:

Hippocampus OU supplies mainly ferrous sulfate monohydrate (FeSO4•H2O, light gray) and ferrous sulfate heptahydrate (FeSO4•7H2O, light green), which are the two most widely used ferrous sulfates in the market.

    1. By particle size of ferrous sulfate: In practical application, size of ferrous sulfate mainly are ferrous sulfate monohydrate powder and ferrous sulfate monohydrate granular. The ferrous sulfate monohydrate particle size distribution is as follows: 6-12 mesh; 12-24 mesh; 20-40 mesh; 60-80 mesh (powder). Ferrous sulfate heptahydrate is mainly produced in powder form.
    2. By production method/technology: Ferrous sulfate is the by-products of titanium dioxide or acid pickling steel. It’s easy to produce ferrous sulfate heptahydrate after slightly dehydrated. There are two kinds of methods to make ferrous sulfate monohydrate from ferrous sulfate heptahydrate, wet and dry methods. The ferrous sulfate produced by wet method is of high content of ferrous and well-controlled lead, arsenic, and Ph value. By wet method only powder form is produced. Ferrous sulfate produced by dry method consists of both particles and powder; it has stable content, uniform particles and less dust, that is suitable for storage and transportation.
