海南鲕状褐铁矿风选-磁选联合试验研究

The joint study by Wind-magnetic separation of Hainan oolitic limonite

以海南鲕状褐铁矿为研究试样,原矿品位40.95%,对原矿采用风选初步脱泥除杂,然后将风选精矿干式磁选再结合还原焙烧,最后再次进行磁选试验,经过一系列联合选矿得到了含铁品位59.21%,铁回收率在84.51%的铁精矿,对其他类似矿山具有借鉴作用。

This experiment take the oolitic limonite from dan state, Hainan province as the test specimen. Ore grade is about 40. 95%. the initial dealing of the ore used winnowing way to desliming and removal impurity, then winnowing concentrate dry magnetic separation in combination with reduction roasting, at last do magnetic separation test again, After a series of joint-grade iron ore-dressing has been 59.21%, 84.51% iron recovery of iron ore, mine has a reference to the role of other similar.
