摘要
以齐大山选矿厂 (齐选厂 )为例 ,对技术改造项目———贫赤铁矿提质降硅工艺改造项目进行经济效益分析 ,证明了科学技术是生产力 ,技术创新创造经济效益。
Taking Qidashan Dressing Plant as example where the dressing process of poor hematite has been improved,the economic benefit of concentrate's iron content increment and silica content decrement is analysed.It is clear that modern science & technology represents powerful productive forces and can bring economic benefit.
