There is a vivid independence and continuity about the origin and development of China's metallurgy. The excavations of archaeology prove: as early as the fifth millennium B.C. far in the Neolithic Age, China had already been in the state with the sufficient qualification in copper smelting. During the early epoch of Xia Dynasty, about 2000 B.C. China possibly reached the Bronze Age. Recently, China has excavated a few of copper alloy artifacts made 2000 to 4000 B.C. the remains of the ancient mine, excavated from Tonglushan of Hubei Province, show: at the age about 1000 B.C. the skill in copper smelting by blast furnace had already been in the state of reaching maturity, the copper content in the slags was very low, only 0.7% in average. That ancient mine might have been in a tremendous large scale at that time, as it is found it smelted about 100,000 tons of copper within over 500 years in succession. The means and methods of smelting copper with blast furnace made a quick progress in China, it soon developed into the blast furnace in iron smelting. China is a country, using cast-iron at a period much earlier than in any other countries in the world, i.e, about 2000 years earlier than the European nations. China, in ancient times, had so many outstanding achievements in the metallurgy of copper and other non-ferrous metals, such as gold, silver, tin, lead, mercury, zinc and copper alloys, etc. The technical skill in metallurgy in ancient China occupied, for a considerable long period, a leading position, offering an important contribution to the whole mankind.

中国冶金的起源和发展具有明显的独立性和连续性。考古发掘表明,远在公元前四、五千年的新石器时代,我国已具备了炼铜的充分条件。到了公元前二千年的夏代早期,可能已进入了青铜时代。近年陆续出土了一些公元前二千年至四千年的铜器。湖北铜录山发掘的古矿遗址说明,在公元前一千年时,鼓风炉炼铜技术已相当成熟,渣含铜很低,平均只有0.7%。该遗址规模宏大,在连续五百余年的时间内大约炼出了10×10~4t铜。鼓风炉技术在我国发展很快,不久就出现了大规模的高炉炼铁。我国是世界最早使用铸铁的国家,比欧洲约早两千年。我国古代在铜及其它有色金属金,银、锡,铅、汞、锌以及铜合金方面,都有许多杰出成就,冶金技术长期处于世界领先的地位,为人类作出了重大贡献。

The ore processed in Datun dressing mill in Yunnan province of China occurs in the hypotermal deposit. This ore is cassiterite-polymetallic sulphide ore with tin, copper, tungsten and bismuth content. Based on investigation results and plant practice a combined dressing-metallurgy technology for treatment of casiterite-polymetallic sulphide ore to separate tin, tungsten, bismuth, sulfur minerals from the rough tin concentrate has been developed. By this technology the run-of-mine ore is crushed, ground and sent to flotation of copper, and other sulphide minerals. The flotation cell product is processed by gravity method to produce rough tin concentrate which is cleaned to yield tin concentrate, tungsten concentrate, tin-tungsten middlings, bismuth concentrate and tin middlings with high sulfur content. These products are upgraded further by metallurgy method. The tin concentrate is direct sent to reduction smelting to yield matallic tin. The tungsten concentrate is refined by chloridizing volatilization to recover tin from it. Tin-tungsten middlings are subjected to decomposition by chlorhydric acid, refining by ammoniacal liquor, crystallization and calcining to produce WO_3 powder and tin concentrate. The bismuth concentrate are treated by chlorhydric acid leaching, electrowinning and refining to obtain metallic bismuth. The bismuth slag is treated by dressing method for recovery of tin. The tin middings with rich sulfur content are to fuming furnace as sulfidizing agent and for recovery tin. As the combined technology has been in operation, high tin recovery (95%) is achieved and 90% sulfur can be used, tungsten recovery is 70%, bismuth recovery is only 39.94% due to fineness of bismuth crystal which presents more in sheet form. This is one subject of investigation in future.

This paper describes a method of ion flotation for separating cobalt, nickel and copper from a solution of manganese ore leached with sulphur dioxide. The separation of copper, nickel and cobalt from solution (42.05 Mn, 3.24 Fe, 0.0996 Co, 0.128 Ni and 0.148 Cu g/l) was carried out with precipitant such as sodium sulfide and ethyl xanthate. Owing to the strong hydrophobility of copper sulfide, xanthates of nickel-cobalt, it was possible to remove the precipitated copper sulfide, xanthate...

This paper describes a method of ion flotation for separating cobalt, nickel and copper from a solution of manganese ore leached with sulphur dioxide. The separation of copper, nickel and cobalt from solution (42.05 Mn, 3.24 Fe, 0.0996 Co, 0.128 Ni and 0.148 Cu g/l) was carried out with precipitant such as sodium sulfide and ethyl xanthate. Owing to the strong hydrophobility of copper sulfide, xanthates of nickel-cobalt, it was possible to remove the precipitated copper sulfide, xanthate of nickel-cobalt from the solution by ion flotation process. The recovery of copper in its sulfide concentrate and recovery of cobalt, nickel in their xanthat concentrate reached about 98% respectively. The testwork results obtained in pilot plant were similar as in bench scale. 6% NaOH was added in two stages, separation of cobalt and nickel were obtained effectively with recovery of ethyl xanthate approximately 60%.

本文叙述从二氧化硫浸出锰矿溶液中分离钴、镍、铜的离子浮选方法。从溶液(42.05Mn,3.24Fe,0.0996Co,0.128Ni和0.148Cu克/升)中,以硫化钠、乙基黄原酸盐作为沉淀剂,实现钴,镍、铜的分离。由于硫化铜、钴镍的黄原酸盐具有强烈疏水性,可用离子浮选方法从溶液中除去硫化铜、钴镍黄原酸盐的沉淀物。铜在硫化铜精矿中,钴、镍在钴镍的黄原酸盐精矿中,均有98%得到回收。扩大试验取得了和小型试验相同的指标。该过程包括分两段加入6%NaOH到钴、镍黄原酸盐中,使钴镍获得有效的分离,约60%的乙基黄原酸盐得到回收。
