Constructing a copper processing plant with a capacity of 15 tons per hour—while considered small-to-medium in scale—still requires a complete and efficient mineral processing system. A well-designed equipment configuration ensures effective ore liberation and maximizes copper recovery rates.

First, the crushing system serves as the initial stage of processing. For a 15 tph throughput, a PE-250×400 jaw crusher is typically selected for primary crushing to reduce large run-of-mine ore to a suitable size. Subsequently, the material undergoes secondary and fine crushing—using either a PEX-250×1000 fine-crushing jaw crusher or a small cone crusher—to reduce the ore to under 20 mm, thereby preparing it for the subsequent grinding stage.

Next, the grinding and classification stages are critical. A GZM-1200×2400 grate-discharge ball mill is recommended to fully liberate copper minerals from the gangue through the impact and grinding action of steel balls. The slurry discharged from the ball mill is processed by an FLG-1200 spiral classifier; material meeting the size requirements proceeds to the next stage, while coarse particles are returned to the ball mill for regrinding. This closed-circuit configuration prevents over-grinding and enhances overall efficiency.

The core separation stage relies primarily on flotation equipment. For this capacity, two SF-1.2 mechanically agitated flotation machines are sufficient. By adding collectors and frothers, copper minerals are made to adhere to rising air bubbles; the material then undergoes roughing, cleaning, and scavenging processes to yield a high-grade copper concentrate.

Finally, a dewatering system is essential. The copper concentrate undergoes initial settling in an NT-10 high-efficiency thickener before entering a chamber filter press for deep dewatering, resulting in a concentrate filter cake with low moisture content. Additionally, auxiliary equipment—such as a ZSW-380×950 vibrating feeder, a B500 belt conveyor, and agitation tanks—is required to ensure the continuous and stable operation of the entire production line.
