Please discuss the application of the Sukagawa copper smelting method in China
Thread Content
The Shuikoushan lead smelting method has been widely used in China, but it is unknown how its copper smelting method is applied there.
Fangyuan in Dongying, Shandong, has already put this technology into use, while Hengbang Co., Ltd. in Yantai, Shandong, is currently in the process of implementing it; not many places are using this technology, that’s all.
The one in Dongying was designed by the Non-ferrous Metals Research Institute, and there are still many problems!
There is also one in Chifeng City, Inner Mongolia; I can’t remember its exact name. They were put into operation in May 2007, and they are still functioning well at present.
It’s impossible; there is only one Jinfeng company in Chifeng, and it uses side-blowing technology!
The Sumigatake smelting method for copper production also has some disadvantages: the grade of copper matte is low—around 48%； The slag contains high levels of copper – over 3% ； The furnace has a low processing capacity per unit volume — 3.2 t/m3*d.
The SKS method is used in lead smelting, and it has seen widespread application in China over the past few years. However, it is only used in copper smelting by two companies: Shandong Dongying Fangyuan Non-ferrous Metals Co., Ltd. and Shandong Hengbang Smelting Co., Ltd. The oxygen bottom-blowing technique they employ represents a development and extension of bottom-blowing technology; it is referred to as a new process for gold extraction through oxygen-enriched bottom-blowing melting. This technology is currently in use abroad by the Viet Nam Thanh Son Copper Joint Enterprise; it is said that a relatively serious accident occurred during trial operations. In any case, there is still a long way to go before bottom-blowing technology can achieve the same level of success in copper smelting as it has in lead smelting.
