Phosphate (P)
High quality phosphate ore is mined in an open pit and 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, and the phosphoric acid is increasingly concentrated for various grades and uses. Monoammonium phosphate (MAP) or 11-52-0 is made by reacting high-quality phosphoric acid 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.
Nitrogen (N)
Urea (46-0-0) is our main source of Nitrogen. Urea is produced through the reaction of ammonia (NH3) and carbon dioxide (CO2). The two are reacted together at high pressure at temperatures between 132° and 182° C (270° and 360° F). The urea solution from these reactions is a molten urea with a concentration of about 80 percent. At this stage, the molten urea solution is further concentrated and then granulated to make dry urea.
Ammonium Sulphate (S)
Granular ammonium sulphate (20.5-0-0-24) is made by combining ammonia and sulphuric acid in a pipe reactor, to produce an ammonium sulphate solution. The solution is sprayed into a granulating drum where the fertilizer granules are formed.
Potassium (K)
Potash deposits (0-0-60) occur in beds of sediments at only a few locations around the world, the largest is located in Saskatchewan, Canada. This deposit which has a thickness from 2.7 m (9 ft.) to 23.5 m (77.6 ft.) is found at depths ranging from 1000 m (3,200 ft.) to 3000 m (10,000 ft.) below the surface. Solution mining methods are used to extract potash from deeper depths. Conventional underground dry-shaft mining methods are utilized in mines up to depths of 1100 m (3500 ft.). Ore is extracted from the potash deposits by electrically operated mining machines and conveyed to the surface where it is crushed. Using a flotation process, common salt and clay particles are removed, the brine solution is dried, and the dried potash is then sized by screening. The resultant coarse grade product is ready for distribution. Fine particles remaining from the screening process are compacted into sheets which are then crushed and screened to particle sizes suitable for blending.
