Abstract:
In order to meet the high national EHS standard for copper smelting production, SKSTM technology was developed in the 1990s. SKSTM copper smelting technology has been commissioned in 2008 at Fangyuan Copper Smelter.
In the past 5 year operation, numerous technique innovations have been implemented in the furnace design. The plant has been successfully demonstrated with its unique excellent performances on all aspects from processing capacity, product quality, energy reduction, cost reduction and emission reduction. The purpose of this report is to update all these improvement with proven tracks.
To demonstrate the superior performances for the modified SKSTM technology, the following aspects are discussed and compared with other similar advanced technologies:
•Plant design and operating conditions;
•Mass and heat balances, metal recovery;
•Consumables, oxygen gun and refractory lining life;
•Energy consumption and operating costs;
•Sulfur capture and emission reduction etc.
It is concluded that the modified SKSTM process is a clean SO2-zero emission process. The process is characteristic of other features such as no extra fuel addition, low capital with a small foot-print design, low OPEX, high throughput, easy operation, long refractory lining life and high productivity (95%+ on line time annually). It offers an alternative cost-effective technology for copper smelting industry.
