Explainer Series | Episode 1: How Neutralization Works
In the first episode of our new explainer series, we take you inside our operations to explore the process principles, technical standards and management practices behind our work. We begin with the neutralization process that takes place before tailings are stored.
Even after cathode copper is produced, the process is not yet complete. During thickening, the copper-rich solution is separated from the remaining solids. The resulting underflow then enters the neutralization system for further treatment before being transferred to the tailings storage facility.
Milk of lime is added to the slurry to adjust its pH and is evenly dispersed through continuous agitation. Multiple pH checks are carried out at different stages, followed by a final verification before storage, to ensure that the slurry is properly neutralized and meets the required standards.
For Sino Metals, neutralization is more than a technical process. It is an important part of responsible tailings management and reflects our commitment to environmental protection and safety compliance throughout our operations.
