摘要
自岔河锡矿开发以来,岔河锡矿作为四川省重要的锡金属资源基地,其资源综合利用效率的稳步提升已成为保障区域经济可持续发展的关键,选矿工艺技术稳步推进,已实现一定规模的锡金属稳定产出。对主要矿石类型(锡石-硫化物型、锡石-磁铁矿-阳起石型、氧化物型)的矿物共生组合、嵌布特征及工艺粒度予以系统分析。随着开采深度增加,矿石中锡石粒度细化、硫化物与脉石共生关系复杂化等问题日益凸显,如何提升深部矿石可选性、降低选矿成本已势在必行。基于此,简要探讨岔河锡矿石类型、工艺特征,探索矿物质组成与可选性的综合关系,以期为复杂锡矿资源高效利用提供技术支撑。
Abstract
Chahe Tin Mine serves as a key tin resource base in Sichuan Province. Its comprehensive resource utilization efficiency has risen steadily since operation, supporting sustainable regional economic growth. Advances in mineral processing technologies have maintained stable, large-scale tin metal output. This work examines three dominant ore types at the deposit: cassiterite-sulfide, cassiterite-magnetite-actinolite, and oxide ores. It details their mineral assemblages, host rock properties, and cassiterite dissemination grain sizes. As mining progresses deeper, two key challenges emerge: cassiterite grains become progressively finer, and sulfides form intricate intergrowths with host rocks. Enhancing deep ore processability and cutting mineral processing costs have thus become pressing technical priorities. Against this backdrop, the paper outlines the ore types and processing characteristics of Chahe Tin Mine, and investigates the correlation between mineral composition and ore processability. The findings offer technical reference for efficient development of complex tin resources.
