From Phosphate Rock to Fertilizer — A Process Overview

The journey from phosphate rock to fertilizer involves multiple steps that transform raw materials into valuable agricultural products. Here's an outline of the key stages:

1. Raw Material Preparation

Phosphate rock is crushed, ground, and purified to remove impurities.

2. Acidulation Process

Phosphate rock undergoes sulfuric acid treatment, producing phosphoric acid and gypsum.

3. Fertilizer Production Paths

Two main pathways:

a. Wet Process (for producing phosphoric acid used in DAP/MAP)

b. Direct Acidification (for producing single or triple superphosphate)

4. Granulation

The fertilizer mixture is granulated, dried, and cooled to form solid, easy-to-apply fertilizer.

5. Quality Control & Final Product

The fertilizer undergoes strict quality control to ensure it meets agricultural standards.

🌍 Environment & Safety

Ensure proper disposal or use of byproducts (e.g., gypsum), and adherence to safety standards during production.
