  试验原矿品位:含铁21.45%。根据原矿性质,试验初步确定采用磁选方法对目的矿物进行回收。试验先进行破碎、筛分作业,利用弱磁机选得部分强磁性矿物,再用滚筒式强磁机回收弱弱磁性矿物。从流程图中可看出:试验原矿品位21.43%,作业产品矿品位39.36%,产率41.21%。未处理-0.5mm粒级产率占41.58%,品位10.2%,试验作为尾矿,综合尾矿产率为58.80%,品位为8.86%。此流程可预先抛出部分尾矿,选别产品直接作为贫矿选厂入选原矿。本次小型试验选别产品是未能达到销售产品质量要求;同时试验规模为小型间断性试验流程,未曾应用连续生产作业,为进一步探索验证试验的可靠性及工业应用的可行性,研究决定对该部分矿石进行工业试验验证、生产成本核算。
