在第一次试验研究结果的基础上，对威远在铁矿的利用问题进行了增补试验。试验结果表明，“破碎→水洗或筛分选矿→烧结”流程是威远菱铁矿经济合理利用的一条可行途径。
On the basis of the results of the first experiment, the supplementary tests on the utilization of iron ore in Weiyuan were carried out. The test results show that the process of “crushing → washing or screening and beneficiation → sintering” is a feasible way for economical and rational utilization of Weiyuan siderite.
