Gold Mining
Industrial mineral solutions — PT Wira Energi Utama, North Sulawesi
Gold Mining Overview
In gold cyanidation, pH control is critical to prevent lethal HCN gas formation. Quicklime or hydrated lime keeps pH above 10.5.
Products Used
Agen pengatur pH utama dalam tangki leaching emas
Digunakan dalam unit pengolahan limbah tailing emas
Role of Limestone / CaCO3 in Gold Mining
Lime neutralizes acid from sulfide mineral oxidation and maintains cyanide solution stability during leaching.
Technical Requirements
| Parameter | Value / Standard |
|---|---|
| Available CaO | > 90% |
| Slaking Rate | Rapid |
| Reaktivitas | T60 < 1.5 min |
| Grit | < 1% |
Process Integration
- 1
pH Conditioning
Kapur ditambahkan ke slurry bijih emas sebelum penambahan sianida.
- 2
Leaching
Emas dilarutkan dalam kondisi pH alkali stabil (10.5–11.5).
- 3
Detoxification
Limbah tailing dinetralisir menggunakan kapur sebelum dibuang ke bendungan tailing.
Industry Pain Points
Konsumsi kapur tinggi akibat mineral sulfida reaktif meningkatkan biaya operasional tambang
Gas HCN terbentuk jika pH turun di bawah 10.0, membahayakan keselamatan kerja
