Quicklime is a key input in many gold processing plants. It does not extract gold directly, but it creates the alkaline conditions needed for efficient recovery. Its main role is to raise and control pH levels throughout the processing circuit.
Sable pH supports more consistent gold recovery. Quicklime also neutralises naturally occurring acids in the ore, helping reduce the amount of extraction chemicals required. Lower chemical consumption can support better cost control, while more stable processing conditions can improve plant efficiency. Quicklime also helps reduce the dissolution of unwanted metals and impurities. This can limit interference in the recovery process and support more predictable plant performance.
Its role is particularly important in cyanide-based gold processing. Cyanide must be kept in an alkaline environment to reduce the formation of toxic hydrogen cyanide gas. By maintaining the required pH, quicklime supports safer operating conditions and helps reduce process risk. This makes quicklime more than a basic industrial material. It is a regular operating input that supports efficiency, safety and consistency across gold processing operations.
Gold plants need continuous access to processing consumables, and interruptions can affect plant stability, chemical use and production schedules.
Quicklime projects located close to mining operations can be well positioned to meet this ongoing demand. Shorter supply routes can also reduce logistics risk and improve access to a material used throughout the processing cycle.
Firering Strategic Minerals plc (LON:FRG) is an emerging quicklime producer and critical minerals explorer, with operations in Zambia and West Africa.
