We will persistently drive technological progress in the field and serve the industry in achieving efficient and low-consumption resource development.

As a key part of the Qidashan Concentrator's process upgrade project, the new flotation system faced challenges such as unstable operation and complex parameter matching since its commissioning under load. The plant adopted a problem-oriented approach, exploring and establishing a "One Guarantee, Two Controls, Three Adjustments" stable-quality operating method. Through phased commissioning and troubleshooting, the flotation concentrate grade was increased from an initial 60% to over 65%, with a peak of 70.5%. This significant achievement marks a critical breakthrough in the commissioning of the new flotation system, laying a solid foundation for the entire process upgrade project to reach its full production and efficiency targets.

Focusing on "One Guarantee" to ensure flotation cell flow-through.

The plant started by ensuring process connectivity, conducting full-flow commissioning under load without adding reagents to systematically verify the slurry flow capacity from the roughing and cleaning stages to the scavenging section's intermediate boxes. Through repeated testing of various combinations of large and small cone valve openings and manual/automatic control modes, the optimal valve control range was finally determined, providing a fundamental guarantee for the stable operation of the flotation cell.

Focusing on "Two Controls" to precisely manage feed rate and pump sump level.

The plant strictly controlled the flotation feed rate, ensuring uniform and stable feed material by adjusting the feed concentration in gradients. At the same time, it strengthened real-time monitoring of the pump sump level, establishing a three-tier control mechanism of "early warning - adjustment - review" to manage the overall overflow rate. This successfully eliminated slurry spillage from the pump sump, creating critical conditions for the continuous and stable operation of the system.

Focusing on "Three Adjustments" to systematically optimize core process parameters.

With the process stabilized, the plant gradually adjusted and optimized the three key parameters: reagent dosage, aeration rate, and pulp level. Through fine-tuning the reagent addition ratio and method, reasonably matching aeration intensity with mineralization requirements, and precisely setting the pulp level, the separation efficiency was further enhanced, driving a step-by-step improvement in flotation performance indicators.
