摘要

The exploitation of thin veins in underground metal mines poses challenges such as low production efficiency, high dilution, and spatial constraints. To advance in-situ ore preconcentration technology, this study investigates the microwave heating behavior of lead-zinc ore arrays, aiming to support microwave-assisted intelligent ore sorting. Through a combination of theoretical analysis and laboratory experiments, orthogonal experiments were conducted to examine the differential thermal response of ore arrays under varying parameters. Infrared thermography was employed to capture pre- and post-heating temperature distributions. Results reveal that array scale, inter-ore spacing, and heating direction significantly influence heating uniformity and efficiency. Smaller arrays yield faster heating but reduced uniformity, while increased spacing enhances thermal uniformity at the cost of heating rate. An optimal inter-ore spacing of 20 mm balances coupling strength and energy distribution. These findings provide a theoretical basis for the application of microwave-induced sorting in mineral processing systems.
