Description
Yellow Phosphorus Smelting Furnace
Precision Phosphorus Extraction by HANI Metallurgy
Engineered for High-Purity Elemental Phosphorus
The Yellow Phosphorus Smelting Furnace is a critical industrial unit used to extract yellow phosphorus (P4) from phosphate rock. As a specialized Yellow Phosphorus Furnace, it utilizes a high-temperature reduction process involving phosphate rock, silica, and coke. At HANI, we have developed advanced phosphorus smelting technologies that integrate fully enclosed designs with state-of-the-art gas condensation systems. Our SAF for yellow phosphorus is engineered to deliver maximum extraction efficiency and energy savings, providing a stable platform for the production of high-purity yellow phosphorus used in the chemical, food, and pharmaceutical industries.
A HANI Yellow Phosphorus Smelting Furnace is designed for ultra-low emission and high reliability. The Yellow Phosphorus Furnace must handle the complexities of phosphorus gas (P4) capture and separation from slag and ferrophosphorus byproducts. Our phosphorus smelting units are equipped with fully automatic charging, electrode management, and furnace interior monitoring. By integrating hot-charging technology and high-efficiency gas purification, HANI’s SAF for yellow phosphorus ensures the highest automation level in the industry, meeting the most stringent global standards for safety and product quality.

Chemical Process of Yellow Phosphorus Smelting
The production of yellow phosphorus in a Yellow Phosphorus Smelting Furnace is based on the carbothermic reduction of fluorapatite [Ca5(PO4)3F] or hydroxyapatite. In the Yellow Phosphorus Furnace, silica (SiO2) is added as a flux to combine with CaO to form a liquid slag, while coke (C) reduces the phosphorus to its elemental gas form. HANI’s phosphorus smelting technology ensures the precise control of the furnace temperature (1300-1500°C) in the SAF for yellow phosphorus.
Overall Reduction Reaction:
2Ca3(PO4)2 + 6SiO2 + 10C → 6CaSiO3 + P4(g) + 10CO(g)
To achieve high phosphorus purity and recovery in the Yellow Phosphorus Smelting Furnace, the removal of impurities like iron and aluminum oxides is critical. HANI’s phosphorus smelting process produces ferrophosphorus as a valuable byproduct, which is tapped separately. Our SAF for yellow phosphorus is also equipped with a multi-stage condensation system that cools the P4 gas to its liquid state, ensuring a safe and efficient collection process.
