FeSO4. H2O is a mineral additive in animal feed. As a blood tonic substance to livestock, it can stimulate the growth of animal's body. It can also be used to make pigment such as red ferric oxide etc.
Also can used to improve the quality of soils and remove the moss and be used as pestiside to cure wheat, fruitteres such as apple, pear etc. It is used to make pigment such as Ferric Oxide series products (such as iron oxide red, Iron oxide black, Iron oxide yellow etc. ).
It can also be directly used as the flocculant for waste water treatment, for purification of water, for producing ferric sulfate, for iron containing catalyst.
