１９８４年北京矿冶研究总院提出的复杂金精矿熔渣炉熔融脱硫造渣工艺方案已获应用，使矿产铜仅３６００ｔ／ａ的烟自冶炼厂金产量达到１．２ｔ／ａ，每年新增利润３００万元。本文对课题的开发、方案的选译做了详细介绍；论述了熔渣炉结构特点和熔炼过程，指出了熔渣炉熔池中充满着呈激烈搅动状态的炉渣熔体，少量硫化物未形成稳定冰铜层；还就熔渣炉熔炼金精矿的技经指标和处理能力的提高，以及磁住氧化铁行为等问题进行了系统总结。床面积仅１．９５ｍ￣２的烟台熔渣炉日处理金精矿可达６０ｔ，冶炼强度高达３０ｔ／ｍ￣２·ｄ。它的首次应用为复杂金精矿处理、小型铜厂和小型铅厂扩大黄金生产开辟了新途径。
In 1984, Beijing Institute of Mining and Metallurgy proposed a complex gold concentrate slag furnace melting desulfurization and slag preparation process has been applied so that only 3,600 t / a of copper from the smelter gold production reached 1.2t / a, new each year Increased profits by 3 million yuan. In this paper, the development of the subject and the selection of the scheme are described in detail. The structure and melting process of the slag furnace are discussed. It is pointed out that the slag bath is filled with molten slag with a violent agitation state, and a small amount of sulfide is not formed Stabilizing the matte layer; and also summarized the technical and technical indexes and processing capacity of the molten slag smelting gold concentrate, as well as the behavior of the magnetic iron oxide. The bed area of only 1.95m ~ 2 Yantai slag furnace daily gold concentrate up to 60t, smelting strength up to 30t / m ~ 2 · d. Its first application was for complex gold concentrate processing, opening up new avenues for small copper mills and small lead mills to expand gold production.
