Application
Animal nutrition
Magnesium oxide is a source of magnesium for some species, which is given to them in different ways:
- A mineral mixture containing magnesia and other additives (vitamins, salts, trace elements, etc.)
- Bucket licks: Magnesia input varies according to the formulation.
- Stone licks: These stones are spread over the pasture for the ruminants to lick
There are a large number of bucket lick formulations. Each responds to a particular need.
Examples :
- Magnesia bucket with vitamins: provides the animal with magnesium
- Trace bucket: provides the animal with additional nutritional value in copper, zinc, iron, manganese, etc.
- Calcium phosphate buckets
- Dry cow bucket: specially designed for cows at the end of lactation
- Etc.
Fertilisation
- Magnesium oxide in powder form, fine grains or balls 2 - 4 mm
- Magnesium sulphate heptahydrate crystals. 100% water soluble
- Magnesium sulphate monohydrate crystals & powder
Industry
The properties of magnesium oxide enable its use in a number of industrial applications such as:
- The production of other magnesium salts such as magnesium sulphate and magnesium nitrate in the chemical industry
- Its properties as catalyst, pigment extender, acid neutralizer are researched in:
- . the plastic manufacturing industry
- . the rubber and coating manufacturing industry, and
- . the food processing industry.
- It is a base ingredient in some product formulations for the steel industry
- It is also used in the paper pulp manufacturing industry as an ingredient, replacing the caustic soda or the calcium in the bleaching stages or in the treatment of waste water.
