1、攀枝花學(xué)院本科畢業(yè)設(shè)計(jì)（論文）國(guó)內(nèi)鉛礦石選礦布點(diǎn)、技術(shù)裝備現(xiàn)狀與發(fā)展研究學(xué)生姓名：劉林學(xué)生學(xué)號(hào)：200611101218院（系：材料工程學(xué)院年級(jí)專(zhuān)業(yè)：2006級(jí)材料科學(xué)與工程指導(dǎo)教師：鄒建新（教授）摘要當(dāng)前，我國(guó)的礦業(yè)形勢(shì)發(fā)生了根本性的變化，首先是選礦技術(shù)、選礦設(shè)備、選礦工藝技術(shù)改造取得了重大突破，工藝裝備水平得到跨越式提升，絕大部分選礦廠的選礦作業(yè)流程都進(jìn)行了優(yōu)化改造；其次，新建礦山數(shù)量大幅度增加，新建礦山選礦廠的技術(shù)水平、裝備水平和自動(dòng)化控制水平都非常高；再次，復(fù)雜難選礦石的選礦技術(shù)取得了重人進(jìn)展，精礦品位、品質(zhì)得到人幅度提高，礦業(yè)經(jīng)濟(jì)取得了
2、輝煌的成果，礦山企業(yè)的規(guī)模、效益同步增長(zhǎng)，一條科技含量高、經(jīng)濟(jì)效益好、資源消耗低、環(huán)境污染少、人力資源優(yōu)勢(shì)得到充分發(fā)揮的新型工業(yè)化路子基本形成。本課題旨在研究國(guó)內(nèi)鈕礦石選礦廠的分布狀況、選礦工藝技術(shù)水平、選礦設(shè)備水平的現(xiàn)狀，對(duì)今后幾年鋸礦石選礦廠的分布調(diào)整、選礦工藝技術(shù)和選礦設(shè)備的發(fā)展趨勢(shì)進(jìn)行展望。因此，本課題對(duì)國(guó)內(nèi)偌礦石選礦技術(shù)、裝備、工程及生產(chǎn)具有重要參考價(jià)值。對(duì)礦產(chǎn)資源開(kāi)發(fā)、選礦工程建設(shè)等具有參考價(jià)值。關(guān)鍵詞：珞礦石，技術(shù)裝備現(xiàn)狀，市場(chǎng)現(xiàn)狀，發(fā)展趨勢(shì)ABSTRACTAtpresent,theminingsituationinourcount
