• One of the earliest known industrial commodities and fundamental raw material for industry
• Limited economically viable substitutes – in most applications cost of replacement with synthetic material is prohibitive
• Facilitates the production of transitional metals while minimising the environmental footprint of any waste materials
• Common forms are Limestone, Quicklime and Hydrated Lime
Naturally occurring form of Calcium Carbonate appearing as beige to white rocks. Limestone aggregate is produced by crushing and sizing limestone rock.
Known for its strong alkalinity, quicklime is an essential industrial compound with a wide range of applications. Quicklime is prized for its efficiency in pH control, impurity removal, and enhancing industrial processes, making it a critical material in numerous sectors.
Hydrated lime is produced by carefully adding water to quicklime, creating a fine, consistent powder with a particle size typically below 100 micron. When blended with sand and cement, it significantly improves the workability, finish, and bond strength of mortars and renders. PLC’s Low Carbon Hydrated Lime, derived from our premium Low Carbon Quicklime, offers the same high performance with a reduced environmental footprint.
Magnetite concentrate produced from the Orokolo Bay Industrial sands deposit. The material contains 57–58% Fe and is processed through screening to remove oversize particles and impurities, followed by multi-stage spiral gravity separation, secondary gravity concentration and dewatering to achieve a stable moisture content. The product is suitable for heavy media separation, steelmaking, refractory applications and other industrial processes.

The material contains 57–58% Fe and is processed through screening to remove oversize particles and impurities, followed by multi-stage spiral gravity separation, secondary gravity concentration, and dewatering to achieve a stable moisture content. The product has low levels of deleterious elements and a tight particle size distribution (P99 ≤ 300 µm), making it suitable for heavy media separation, steelmaking, refractory applications, and other industrial processes.
