1. Efficiency and profitability advantages
Recovery rate leads the industry
• Adopting the "pre-waste disposal + flotation enhancement" process, the comprehensive copper recovery rate is ≥88% (measured data of Mexican high-sulfur ore), which is 5%-8% higher than the traditional process.
• Collaborative recovery of associated gold and silver: Through reagent optimization, the recovery rate of gold and silver is simultaneously increased to 65%-75%, and an additional income of 5%-10%.
Stable concentrate quality
• The copper grade of the concentrate is 25%-30% (the standard for the Mexican smelter is ≥20%), and the water content is ≤12%, which directly meets the trade requirements without secondary processing.
2. Cost control advantages
Investment savings
• Equipment selection accurately matches the hardness of Mexican ore (Bond work index 12-15kWh/t), "two-stage crushing + single-stage ball milling" design, saving 25% of infrastructure investment and 35% of energy consumption compared with traditional three-stage crushing.
• Modular layout: supports gradual expansion from 200 tons/day to 500 tons/day to avoid repeated investment.
Operation cost optimization
• Reagent compounding technology (yellow medicine/black medicine + customized inhibitor), reagent cost per ton of ore ≤ US$1.2 (industry average US$1.5-2).
• Tailings dry discharge + water return circulation: water resource utilization rate ≥90%, wastewater treatment cost reduced by 60%
3. Flexibility and reliability
Wide adaptability of ores
• Compatible with sulfide ores (chalcopyrite, bornite) and oxide ores (malachite), and special solutions are designed for complex ores such as high sulfur (S content 15%-30%) and high arsenic (As ≤ 0.5%).
Risk-resistant design
• "Diesel + photovoltaic" hybrid power supply system: to cope with fluctuations in the Mexican power grid, ensuring an annual operating rate of ≥ 95%.
• Intelligent monitoring system: German Siemens PLC control + vibration sensor, real-time warning of equipment abnormalities, reducing the failure rate by 40%.
