Firering Strategic Minerals’ Limeco limestone project, located about 22 km west of Lusaka in Zambia, gives investors a direct look at a practical part of the mining supply chain. The project produces quicklime and hydrated lime from a vertically integrated facility, using limestone mined from a nearby quarry.
During the recent WhyAfrica Business trip to Zambia, the Limeco operation showed how limestone is moved from quarry to kiln. After blasting and mining, the limestone is delivered to a skip hoist, which carries the rock to the top of the kiln. From there, the material moves slowly down through the kiln while being heated to around 900°C to 1,100°C.
This heating process is critical. At these temperatures, carbon dioxide is driven off and the limestone is converted into quicklime. If the temperature is too low, the limestone is not fully converted, which affects the quality and usefulness of the final product. For industrial customers, especially mining companies, consistent quality is essential.
Quicklime is an important input for mining. It is used to control acidity, improve mineral recovery during processing, treat water and help remove impurities during metal production. These uses make lime a necessary part of efficient and responsible mining operations. Without lime, many mines would find it harder to recover minerals effectively or meet environmental standards.
Limeco supplies a product that supports mineral processing rather than depending directly on commodity discovery. That gives it a different type of exposure to the mining sector, focused on industrial demand, operational reliability and supply chain positioning.
Firering Strategic Minerals plc (LON:FRG) is an emerging quicklime producer and critical minerals explorer, with operations in Zambia and West Africa.
