葫芦岛锌厂1986年以前的年生产能力是6万吨锌、17.5万吨硫酸,产品单一。从1986年起开始技术改造。到1994年底,预计达到生产能力:精镏锌20万吨,硫酸80万吨、精铜6万吨、电解锌13万吨,装机容量3万千瓦的热电厂,是我国目前最大的有色金属冶炼厂。1993年实现利税2.24亿元,比1985年增加了3.31倍。该厂为什么在较短的时期内能获得如此高速发展,其主要经验 Huludao Zinc Plant 1986 before the annual production capacity of 60,000 tons of zinc, 175,000 tons of sulfuric acid, a single product. Since 1986, technological transformation began. By the end of 1994, it is expected to reach the production capacity of 200,000 tons of refined zinc, 800,000 tons of sulfuric acid, 60,000 tons of refined copper, 130,000 tons of electrolytic zinc and 30,000 kilowatts of installed capacity. It is now the largest non-ferrous metal smelter in China . Profits and taxes of 224 million yuan were realized in 1993, an increase of 3.31 times over 1985. Why the plant in a relatively short period of time so rapid development, its main experience
