為此,決定對焙燒礦進(jìn)行階段磨選,即先在較粗的磨礦細(xì)度下通過弱磁粗選拋棄一部分尾礦,然后對粗選精礦進(jìn)行再磨精選,以降低細(xì)磨礦量,減少泥化對鐵回收率的影響。可以看出,采取階段磨礦、階段弱磁選措施后,鐵回收率得到了提高,同時(shí)保證了精礦鐵品位在6%以上,但精礦中磷含量為.496%,不符合冶煉要求,須通過反浮選將磷降至.3%以下。反浮選降磷試驗(yàn)以碳酸鈉為pH調(diào)整劑、淀粉為鐵礦物的劑、PB為磷礦物的捕收劑、2#油為起泡劑,對弱磁選精礦進(jìn)行一粗一精反浮選,結(jié)果使精礦中的磷含量降到了.225%。

一般的引水配水工程,設(shè)計(jì)流量必須局限在一定的范圍之內(nèi),避免流速超越臨界值引發(fā)爆管。那么“真空流”會不會產(chǎn)生爆管危險(xiǎn)?它流速過大的優(yōu)勢會不會產(chǎn)生其它的副作用?筆者就這個(gè)問題,對一項(xiàng)已實(shí)施的真空輸水工程進(jìn)行流量的壓力測試。為了達(dá)到配水管網(wǎng)的流量,筆者打開管網(wǎng)中位于點(diǎn)的排污閥,加大流速水頭。同時(shí)觀察流量表和壓力表的示數(shù)變化。測試結(jié)果:配水流量迅速增加到原來的6%,主管的流速增加到原來的8%,流速、流量均已突破臨界值,而管內(nèi)壓力反而下降了.5公斤。
