A glimpse into our activities
and product range

Olmix Group’s Trace Element Division is based on two main activities:


Iron Sulphate production

Olmix is a recognized specialist in the production of Iron Sulfate, with Olmix Nordenham Gmbh plant (Germany) standing out as one of the most innovative and important manufacturing units in Europe in terms of production capacity (30,000 tons per year).

We offer Iron Sulfate in several forms:

  • Heptahydrate iron sulfate: available as crystals (Iron Sulphate Heptahydrate S technical snowcrystals) or fluidized form (Ferromel 17 – fertilizer application)
  • Monohydrate iron sulfate: Ferromel 30, produced using the innovative fluidized bed dryer technology, which results in a very fluid, granulated, stable, and homogeneous monohydrate iron sulfate of high quality.
