Our Mono Ammonium Phosphates are derived from reaction of high-quality phosphoric acid with ammonia that helps produce hot MAP slurry. Besides, for grade control, a small amount of sulphuric acid is added that turns the slurry into solid granules in the granulator. These are sized for uniform blending and reduces handling requirements.


Preparation:

• Phosphate ore is mined in an open pit
• Processed into a fine powdered rock
• The rock is reacted with water and sulphuric acid to produce a slurry of phosphoric acid and gypsum solids
• The gypsum is filtered from the slurry
• The phosphoric acid is increasingly concentrated for various grades and uses
• phosphoric acid is reacted with ammonia to produce a hot MAP slurry
• A small amount of sulphuric acid is added for grade control
• The slurry is turned into solid granules in the granulator
• The granular product is dried and screened
• Product that is too large or too small is recycled to the granulator

Benefits:

• High analysis reduces handling requirements
• Sized for uniform blending
• Application flexibility
• Consistent quality
• Dust free
