Abstract: The application of humic acid in the smelting, removed the sintering process, and used other carbon material to replace partial metallurgical coke, realized the standard reduction of reduction in smelting process. It has achieved low-carbon and circulation. The effect of energy conservation and emission reduction is remarkable, and great benefits is achieved. So it has far-reaching significance.

Key words: humic acid; standard reduction; energy conservation and emission reduction

冶炼离不开焦炭，以钢铁为例，2009年我国生产粗钢5.67亿吨，按平均焦铁比0.6计算，每年冶炼行业需要焦炭3.41亿吨。在生产焦炭的过程中，排放大量的烟尘、废水和工业废气，按2009年冶炼所需焦炭计，每年排放SO2 34.93万吨，工业废水4.09亿吨，烟尘30.25万吨，工业废气6723.25万吨，能耗4724.45万吨标煤。
