In order to resolve a series of growing environmental problems that appeared because of the mine tailings, the author paid attention on the feasibility of converting the mine tailings into farmland, and the mine tailings was produced by Benxi iron and steel (group) mining co., ltd. The results showed that: lettuce in the ratio of 100% powder grew best under the circumstances; cabbage in 6 levels had no effects on growth; carnation grew best when the ratio was 50% soil+50% of the local pink; the growth of raincoat cabbage was good in the ratio of 80% local soil+20% powder. It was indicated that acidic tailings, with Benxi local soil was alkaline, doping was used to field, was feasible and effective. The conclusion was that it was the best effect that mixing the Benxi’s mine tailings and the local soil, meanwhile, fertilizing organic fertilizer into farmland.
