In the context of the industry where global gold demand continues to rise and ore grades are declining year by year, mining companies are in urgent need of reducing costs and increasing efficiency through technological upgrades. With "high recovery rate, low operating cost, and full-scenario adaptation" as its core competitiveness, Jinhui gold beneficiation equipment provides gold mining companies with a one-stop solution from ore pretreatment to concentrate purification, helping customers maximize profits in the development of complex ore bodies.
System architecture: six core modules work together
Gold beneficiation equipment adopts a full-process integrated design of crushing-grinding-gravity-flotation-leaching-smelting, supporting modular rapid assembly and flexible expansion of production capacity. The equipment is equipped with an Industrial Internet of Things (IIoT) hub platform to collect 150+ key parameters such as ore hardness, particle size distribution, and reagent concentration in real time, and dynamically optimize the process chain efficiency through algorithms.
Core parameters: Covering 3000-10000 tons/day processing capacity
● Crushing section: Using jaw crusher + cone crusher + vertical shaft impact crusher three-stage crushing process, the ore is crushed to -12mm accounting for more than 90%, and the energy consumption is reduced by 25% compared with the traditional process.
● Grinding section: Equipped with large ball mill + cyclone group, the grinding fineness can reach -200 mesh accounting for 85%-92%, and the power consumption per ton of ore is only 12-15kW·h.
● Purification section: Customized combination of gravity separation (ore dressing machine) + flotation (inflatable flotation column) + carbon leaching (CIL/CIP) process for different types of ores, to meet the 0.5-15g/t grade ore processing needs.
Five core advantages: Why do global mines choose Baichy Heavy Industry?
1. Gold recovery rate increased to 95%-98%
● Multi-process synergistic efficiency: The "gravity pre-enrichment + flotation concentrate re-grinding + enhanced leaching" solution is adopted for fine-grained gold, and the recovery rate is increased by 20%-30% compared with the single process.
● Intelligent reagent control system: Automatically adjust the amount of collector and inhibitor based on real-time analysis of ore composition to reduce the loss of precious metals.
2. The cost of processing a ton of ore is reduced by 18%-25%
● Economic purification of low-grade ore: For gold ore below 1g/t, the cost of processing a ton of ore is only 45-60 yuan through biological oxidation heap leaching technology, and the investment payback period is shortened to 1.5 years.
● Waste heat recovery system: Use smelting waste gas to preheat the slurry, saving more than 2 million yuan in coal costs per year (calculated at a scale of 5,000 tons/day).
3. Globally leading environmental compliance
● Cyanide zero discharge technology: Using the INCO tailings treatment process, the cyanide decomposition rate is 99.99%, which complies with the EU Mining Wastewater Discharge Directive (2020/2184).
● Tailings dry discharge system: The tailings moisture content is less than 15%, which can be directly used for backfilling of goafs or building materials production, reducing the footprint of the tailings pond by 60%.
4. Intelligent operation and maintenance to ensure continuous production
● Digital twin system: 3D visualization of equipment operation status, and fault location time is shortened to within 10 minutes.
● Spare parts prediction and replenishment: Intelligently push spare parts procurement plans based on equipment wear models, and reduce inventory backlogs by 40%.
5. Full life cycle service support
● Process package optimization service: Free ore selectivity test and customized process flow plan.
● Energy efficiency hosting model: Promise "full compensation for ton of ore processing costs that do not meet the standards" to reduce customer investment risks.
Four gold purification scenarios in practice
Scenario 1: High-grade primary ore (gold grade 5-20g/t)
Case: A large gold mine in South Africa (800 tons of reserves)
Pain points: The ore contains high sulfide, the gold particles are complexly embedded, and the traditional flotation recovery rate is only 82%.
Solution: Adopt the combined process of "semi-autogenous grinding + flotation column + pressurized oxidation leaching".
Results: The gold recovery rate is increased to 96.5%, the annual gold production is increased by 1.2 tons, and the reagent cost is saved by 3 million yuan.
Scenario 2: Difficult to handle oxidized ore (mud content>30%)
Integrated ultrasonic ore washing + spiral graded dehydration pretreatment system, the mud interference is reduced by 70%.
Using thiourea instead of cyanide leaching process, the leaching cycle is shortened from 48 hours to 18 hours.
Scenario 3: Tailings re-selection (gold grade 0.3-1.2g/t)
By applying high-pressure roller mill activation + resin slurry method (RIP), the tailings gold recovery rate can reach 50%-65%.
Taking the treatment of 1 million tons of old tailings as an example, 600-1200 kg of gold can be extracted, creating a value of 240-480 million yuan.
