How Is Easily Oxidized Gold Ore Processed for Maximum Recovery?
In nature, oxidized gold deposits that are easy to process are widely distributed on or near the surface.
Due to their low processing cost and simple beneficiation process, they are highly favored by mining companies worldwide.
Characteristics of Easily Oxidized Gold Ores
Easily processed oxidized gold ores typically have the following features:
- Highly weathered structure
- Very low sulfide content
- Abundant free gold
- Cyanide solution easily penetrates the rock
- Generally large ore reserves
This type of ore is preferred because the blasting, crushing, and grinding stages are simpler, and the overall beneficiation cost is much lower compared with refractory gold ores.
Common Separation and Leaching Methods
Based on extensive production experience, Dasen Mining Machinery summarizes two suitable processes for oxidized gold ore beneficiation:
- Low-Grade Ore:
→ Direct gold heap leaching, or crushing followed by heap leaching.
- High-Grade Ore:
→ Grinding and then leaching with sodium cyanide.
These processes provide efficient recovery with minimal operational cost.
