2、一。在廢棄的尾礦庫開展資源回收利用,既可解決尾礦砂排放量大所帶來的環(huán)境影響,又可延長尾礦庫的使用年限,減少尾礦庫占用面積,是貫徹科學(xué)發(fā)展觀的有效手段和發(fā)展方向。某礦根據(jù)尾礦庫實際現(xiàn)狀,在科學(xué)考察試驗的基礎(chǔ)上,提出了對老尾礦庫實施尾砂資源回收工程,并于2005年底投產(chǎn),近5年來,已累計生產(chǎn)品位66的鐵精粉112.8340萬t,創(chuàng)效益近5.25億元。本文重點對該礦尾砂資源回收情況進(jìn)行介紹,為礦山資源挖潛引出新路。關(guān)鍵詞:尾礦資源;利用;實踐中圖分類號:TD926.4文獻(xiàn)標(biāo)識碼:B文章編號:1004—4051
