我公司在建厂期间,由于原料含硫低,含水分高等原因,未曾采用沸腾焙烧工艺,而用了回转窑。回转窑的热利用率低,烟气不能制酸,污染环境严重,焙砂物理规格差,不利于用电炉处理。经金川资源综合利用科研任务落实会议决定,由长沙矿冶研究所、金川有色金属公司、北京有色冶金设计研究总院共同承担镍
During the construction of our company, due to low sulfur content of raw materials, high moisture content, boiling boiling process has never been used, and the use of rotary kiln. Rotary kiln heat utilization rate is low, the flue gas can not acid, pollute the environment, calcined poor physical specifications, is not conducive to using electric furnace treatment. The Jinchuan resources comprehensive utilization of scientific research task to implement the meeting decided by the Changsha Institute of Mining and Metallurgy, Jinchuan Nonferrous Metals Company, Beijing Nonferrous Metallurgical Design and Research Institute shared nickel
