云南永昌铅锌股份有限公司资源开发利用实践

主要论述了在加强矿山地质工作、合理开发综合利用矿产资源等方面采取的方法：加强井下生产勘探，采用不同的勘探手法，圈定矿体产壮形态，为采矿提供可靠的地质依据，根据矿体产状形态采用不同的采矿方法，降低贫化、损失率，在选矿方面采用组合药剂提高选矿回收率，在冶炼方面利用新技术、新工艺降低渣含锌，综合回收利用有价金属，提高资源利用率。通过采取以上措施，扩大了资源储备，提高了资源综合利用率，保护了环境，为企业持续稳定生产发挥了重要的作用。

The Practice of Resources Development and Utilization in Yunnan Yongchang Lead & Znic Co.,Ltd.

The paper focuses on measures of strengthening geological work, rational development and comprehensive utilization of mineral resources and so on, such as, strengthening of underground exploration and production, using different methods of exploration, selecting the ore body to achieve strong production patterns, it provides the reliable geological basis for ore dressing. According to ore body occurrence patterns, different mining methods are adopted, which can reduce the depleted ore and the loss rate. The ore dressing recovery rate is improved for using of combinations pharmacy. After introducing new smelting technology and process, lower zinc slag is obtained, comprehensive recycling utilization of valuable metals is achieved, and resource utilization is improved. By taking above measures, my company expands the reserve of resources, improves the comprehensive utilization of resources, and protects the environment, all those play an important role for sustainable and stable production.
