Ferrous sulfate is an iron salt that is commonly used as an iron supplement. Iron supplements are used to treat or prevent iron-deficiency anemia. In iron deficiency anemia, a lack of iron reduces the production of hemoglobin. Hemoglobin allows red blood cells to transport oxygen around the body as well as giving red blood cells their color.

Process Processing of the ore ranges from simple crushing and screening to a standard size, through to processes that beneficiate or upgrade the quality of the iron ore products.
2. Iron ore screening process: Iron ore screening equipment generally uses a circular vibrating screen to screen the materials after the second crushing. Generally, materials with a size of 10mm or less can be screened for dry selection. After screening, materials with a size of 10-40mm enter the fine crusher for fine crushing.
Crushed stone: The term "crushed stone" usually refers to stone that has a mixture of stone dust in it. This type of stone is best used for a base when heavy compaction is needed. As a result, it is typically used for the base of concrete and paving projects, foundations of structures, and driveway bases.
