In the gold beneficiation industry, a flotation plant with a processing capacity of 500 tons per day (TPD) requires sophisticated equipment configuration to efficiently recover gold ore. The core of such a plant lies in separating gold from other impurities through flotation, and the equipment layout directly impacts production efficiency and economic benefits.

Crushing and Grinding System: Crushing equipment begins the process by initially breaking down the raw ore. Jaw crushers are typically used for primary crushing, followed by cone crushers for secondary and fine crushing, ensuring a suitable particle size for subsequent processing. The grinding stage utilizes a grate ball mill, coupled with a high-weir classifier in a closed circuit, to grind the ore to a fineness suitable for flotation (approximately -200 mesh), creating conditions for mineral separation and flotation. Energy management in the grinding system is crucial; optimizing equipment power can significantly reduce operating costs. 

Flotation and Dewatering Equipment: Flotation is the core of gold recovery. Multiple XCF and KYF flotation cells are deployed, using chemical agents to modify the surface properties of the ore, causing the gold minerals to float to the surface with attached bubbles, forming a concentrate. The number of flotation cells in the concentrating process must be precisely controlled to avoid excessive flotation, which can lead to a decrease in concentrate grade. High-efficiency thickeners and chamber-type membrane filter presses are used in the dewatering stage to minimize concentrate moisture content, facilitating transportation and smelting. The diameter and depth of the thickeners must be designed to match the processing capacity to ensure efficient slurry settling.

Auxiliary and Environmental Protection Facilities: Agitation tanks are used to mix reagents and ensure uniformity in the flotation reaction; circulating water tanks collect tailings water for reuse, meeting environmental protection requirements. Furthermore, the appropriate configuration of emergency water tanks and initial rainwater collection tanks effectively mitigates environmental pollution risks. The overall equipment must be customized to suit the characteristics of the ore. For example, for ores with high clay content or carbon content, adjustments to the reagent system or the addition of a pretreatment unit may be required.

This configuration achieves a stable, high gold recovery rate (approximately 90%) through the efficient synergy of crushing, grinding, flotation, and dewatering, while balancing resource utilization and environmental protection.
