Lime remains an important industrial material across water treatment, mining, construction and manufacturing, with its chemical properties supporting applications ranging from pH control to the removal of impurities.
In water and wastewater treatment, lime is used to adjust pH and help remove contaminants from water. It can assist in the treatment of minerals including calcium and magnesium compounds, while also supporting processes designed to reduce pollutants before treated water is discharged.
These applications extend across municipal water systems, industrial facilities and mining operations. In mining, lime can be used to treat wastewater generated during mineral processing, helping manage acidity and reduce unwanted substances before water is returned to the environment.
The ability to control water chemistry makes lime useful across different stages of treatment. Depending on the process, it can help precipitate dissolved substances, neutralise acidic water and improve the effectiveness of subsequent treatment processes.
Lime is also used in mineral processing, including gold mining. Quicklime can help regulate pH during processing and contribute to the separation and recovery of minerals. Its use in these operations reflects the broader role of lime as a process material rather than simply a construction product.
Beyond mining and water treatment, the wider lime market is supported by demand from steel production, construction and environmental applications. Quicklime and hydrated lime have different properties and are selected according to the requirements of individual industrial processes.
Steelmaking is another major application. Lime is used as a flux during the production process, where it helps remove impurities and supports the formation of slag. Demand from the steel industry therefore provides an important source of industrial consumption.
Environmental applications are also becoming increasingly relevant as industries focus on managing emissions, wastewater and other pollutants. Lime-based products can be used in processes designed to treat industrial waste streams and support compliance with environmental requirements.
Firering Strategic Minerals plc (LON:FRG) is an emerging quicklime producer and critical minerals explorer, with operations in Zambia and West Africa.
