较详细地介绍了遵义锰矿石精矿絮凝脱水的工业试验情况．工业试验表明：絮凝剂，斜板机以及自动压滤机的联合应用，可有效地改善锰精矿的浓缩脱水效果，使浓缩溢流浓度从２／～５％降到１％以下，锰精矿产率提高５％～６％；回收率提高６％～７％；滤饼水分从１５％以上降为１４％以下．工业试验为选矿车间全面改造精矿浓缩脱水方案的选择提供了可靠的依据．
The industrial experiment of flocculation dehydration in Zunyi manganese ore concentrate is introduced in detail. Industrial tests show that the combined application of flocculant, inclined plate machine and automatic filter press can effectively improve the concentration and dehydration effect of manganese concentrates, reducing the concentration of concentrated overflow from 2 / ~ 5% to below 1% Minerals increased 5% to 6%; recovery increased 6% to 7%; cake moisture from 15% to 14% or less. Industrial tests provide a reliable basis for the comprehensive selection and reform of concentrates dewatering program in dressing workshops.
