The presented paper presents the results of laboratory tests aimed at verifying the suitability for use as a biomass reducing agent in the form of sunflower pellets for the reduction of nonferrous metal oxides. A number of research techniques were used to verify the behavior of the tested material in the reduction process. The techniques used are mainly based on the use of high temperature, which is characteristic of metallurgical processes. The obtained results indicate that this material has similar values to other raw materials of this type in terms of heat of combustion at the level of 16 to 19 MJ kg⁻¹ and the content of volatile components at the level of 75 pct by mass. Research on the reduction of copper slags using sunflower pellets was carried out in various variants of duration and the amount of reducing agent added. The temperature of 1300 °C adopted in the tests reflects the actual process conditions. The obtained results indicate that with the increase in the amount of reducing agent added from 5.67 up to 12.0 wt pct, the degree of transition of copper and lead to the metallic phase increases from approximately 24 to 56 pct.

本文介绍了实验室测试的结果，旨在验证向日葵颗粒形式的生物质还原剂是否适合用于还原有色金属氧化物。使用了多种研究技术来验证测试材料在还原过程中的行为。所使用的技术主要基于高温的使用，这是冶金过程的特征。获得的结果表明，该材料在16至19MJ kg ^-1水平的燃烧热和75质量%水平的挥发性组分含量方面具有与该类型的其他原材料相似的值。对使用葵花球团还原铜渣进行了不同持续时间和还原剂添加量的研究。试验中采用的1300℃温度反映了实际的工艺条件。所得结果表明，随着还原剂添加量从5.67wt%增加到12.0wt%，铜和铅向金属相的转变程度从大约24%增加到56%。
