目前，國內(nèi)外鉛冶煉過程中錫金屬的回收，通常采用先除銅后撈錫工藝，由于生產(chǎn)過程中銅浮渣含錫高，影響錫金屬回收，錫金屬的回收率在85%左右徘徊。今年初，該公司組建技術(shù)攻關(guān)小組，對提高鉛電解錫回收率開展技術(shù)攻關(guān)。技術(shù)人員大膽創(chuàng)新，打破傳統(tǒng)工藝瓶頸，嘗試采用先撈錫后除銅工藝探索。他們克服了生產(chǎn)對實驗研究的影響，邊生產(chǎn)邊實驗，經(jīng)過近4個月的反復(fù)實踐與探索獲成功。新工藝成功應(yīng)用于生產(chǎn)后，錫金屬回收率穩(wěn)定在92%左右，銅浮渣率降低50%以上，為該公司帶來新的效益增長點。
