Phosphate Uses

Phosphate is a critical mineral resource used primarily in agriculture to support healthy plant growth and food production. It plays an essential role in the creation of fertilizers, especially those that supply phosphorus — one of the three major nutrients (NPK) required for crops to grow strong roots, develop early, and yield abundantly. At Prime Integrated Mills Ltd., phosphate is used to produce ammonium-based fertilizers like Monoammonium Phosphate (MAP) and Diammonium Phosphate (DAP). These fertilizers are vital to improving soil fertility, especially in phosphorus-deficient areas common across Africa. Beyond agriculture, phosphate is also used globally in various industries such as:

Food processing (as additives)

Water treatment

Animal feed supplements

Industrial cleaning products

However, at PrimeMills, our focus remains clear — to harness locally sourced phosphate for sustainable fertilizer production that empowers African farmers and strengthens food security from the ground up.

Phosphoric Acid

Phosphoric acid is a key intermediate product in the production of phosphate-based fertilizers. It is derived from naturally occurring phosphate rock and is used to manufacture highly effective fertilizers like Monoammonium Phosphate (MAP) and Diammonium Phosphate (DAP) — both essential for enhancing soil fertility and increasing crop productivity.
At Prime Integrated Mills Ltd., our long-term vision includes building a fully vertically integrated fertilizer production process, where phosphoric acid is sourced directly from phosphate rock mined under our exploration licenses in Sokoto and Kebbi States. By producing phosphoric acid locally, we can reduce production costs, ensure consistent quality, and decrease reliance on foreign imports.
This step not only strengthens our fertilizer supply chain but also supports environmentally responsible practices, as we aim to combine phosphoric acid with green, renewable ammonia to produce sustainable fertilizers tailored for African soils.
Through phosphoric acid production, PrimeMills is creating a more self-sufficient, scalable, and climate-conscious agricultural industry for the future.

Ammonium Phosphate Fertilizer

Ammonium phosphate fertilizers are a highly effective type of compound fertilizer that combine ammonia (nitrogen) and phosphoric acid (phosphorus)—two essential nutrients that crops need for healthy growth. The most common forms are Monoammonium Phosphate (MAP) and Diammonium Phosphate (DAP), both widely used in modern agriculture to improve soil fertility and crop yield.
At Prime Integrated Mills Ltd., we are focused on producing these ammonium phosphate fertilizers locally, using high-grade raw phosphate sourced from our licensed exploration sites in Sokoto and Kebbi States, combined with green ammonia produced from renewable sources. This ensures that our fertilizers are not only effective but also environmentally responsible and economically sustainable.

MAP(Monoammonium Phosphate) is ideal for early root development and is commonly used at planting.

DAP (Diammonium Phosphate) offers a higher nitrogen content and is suitable for boosting growth throughout the season.

By producing ammonium phosphate fertilizers in Africa, for Africa, PrimeMills is helping reduce reliance on imports, lower farming costs, and provide reliable access to high-quality crop nutrition for farmers across the region.
