研究了在常压下用两段逆流浸出工艺浸出某国外进口菱锰矿石，考察了酸矿质量比、浸出温度、浸出时间以及磨矿细度对一段浸出锰浸出率的影响。结果表明，一段浸出最佳条件为矿石细度－0．124 mm（－120目），浸出温度60℃，酸矿质量比为0．7，浸出时间4 h，最佳条件下做两段逆流浸出综合试验，锰总浸出率可达到98．33％，浸出渣锰含量为1．49％。

This article made a research of atmospheric press with two segments upstream to dip out process imports dialogite,including investigation of acid ore’s ratio to quality,temperature,time and fine degrees of milling to dip out Mn in a rate of effects.Results show that the period of optimum conditions of leaching ore fineness is-0.124 mm(-120),the leaching temperature is 60℃,acid mine mass ratio is 0.7,dipping time of is 4 h under the best conditions to finish two countercurrent leaching test.Total manganese leaching rate can reach 98.33%, leaching residue of manganese content of 1.49%.
