Improve feed grade, cut processing cost, improve efficiency, and unlock more resources
Seperate low-grade ore or waste rock from high grade ore before entering the concentrator, to raise feed grade, and reduce downstream processing unit costs.
Pre-concentration raised Sb grade from 0.089% to 0.730% (8.2× enrichment) with 98.5% waste rejection, substantially reducing downstream processing unit costs.
Re-process waste rock stockpiles to recover high-value concentrate. Processed rejects can be sold as construction aggregate, improving solid-waste utilization and reducing environmental impact.
Historical waste rock was upgraded from 0.42% to 1.72% Cu and from 0.11% to 0.35% Co, while the rejected rock was sold as construction aggregate.
Pre-concentrate at the mine site to reject waste, raise ore grade, lower long-distance unit transport costs, and improve logistics efficiency.
The mine and processing plant are nearly 4,000 km apart. Mine-site sorting rejected 67% waste rock, doubled lithium grade, and improved transport efficiency by 600%.
Reduce unit processing costs and lower the effective cut-off grade to unlock more mineable resources, extend mine life, and improve mine valuation.
After long-term mining reduced the ore grade, sorting raised copper from about 0.1% to 0.3%, turning tens of millions of tonnes of low-grade stockpiled material into a potential resource.
When ore prices fluctuate sharply, add sensor-based sorting to increase capacity without fully rebuilding the existing plant and capture market opportunities.
Pre-concentration delivered 1.6× enrichment and 45% waste rejection, freeing downstream plant capacity for more run-of-mine feed and nearly tripling final metal output.
Reject low-grade ore and waste rock before grinding and flotation to reduce tailings generation at source and extend storage life.
Pre-concentration rejected 17% waste before grinding and flotation, reducing tailings at source. Combined with other process upgrades, the project ultimately achieved zero tailings discharge.
Pre-concentrate ore before downstream processing to improve efficiency and reduce costs
Differences in mineral properties are captured by sensors and interpreted by intelligent algorithms, allowing valuable ore and waste rock to be separated through high-speed air ejection.
Proven sorting performance across 30+ ore types
Integrated R&D, manufacturing, and field service
Since its establishment in 2015, HPY has remained committed to innovation in ore sorting. By integrating artificial intelligence, optical sensing, computer vision, ore recognition, and mechanical automation, HPY has developed sensor-based ore sorting solutions specifically for the mining industry—helping mining companies reduce costs, improve efficiency, and advance sustainable development.
Rooted in China and serving the world, HPY technology is now used at more than 100 mining operations worldwide. We are putting our commitment into practice: “Making Every Ore Count.”
