Gold mining remains one of the world’s most economically significant extractive industries, yet its profitability hinges heavily on the cost of processing gold ore—a complex metric influenced by ore grade, mineralogy, processing technology, geographic location, and regulatory requirements.

Taking a CIL concentrator processing conventional oxidized ore as an example, the processing cost per ton of ore can be broken down as follows (converted at 1 USD ≈ 7.3 RMB, aligned with 2025 global gold beneficiation cost benchmarks):
1. Energy Cost (≈ 30–40% of Total Cost)
- ?????????? ???? ???????? (??????? ????? ????): $3–$6/ton. To liberate gold particles, ore must be ground to an extremely fine particle size, making this the largest energy expenditure.
- ?????? ????? ???????? (??????????, ????????, ????????): $1–$2/ton
2. Material & Reagent Cost (≈ 25–35% of Total Cost)
- Cyanide: $0.68–$2.74/ton. Consumption is highly affected by impurities in the ore, making it a core variable cost.
- ?????? ?????? & ???????: $1–$3/ton. Sustained wear-and-tear during the grinding process.

Key Insight: Gold mining costs are driven by a "dual-high" model — high energy consumption (physical crushing/grinding) and high reagent consumption (chemical extraction). Refractory ores face a "third extreme": massive investment and energy demands in the pre-treatment stage.
