我國(guó)是一個(gè)銅緊缺國(guó)，每年銅需要量約 100萬(wàn)噸，缺口部分 尚需進(jìn)口，雖然我國(guó)銅總儲(chǔ)量不少，但能經(jīng)濟(jì)地利用傳統(tǒng)選冶工藝處理的銅礦越來(lái)越少，過(guò)去一直未被開(kāi)發(fā)利用的難選氧化銅礦和低品位銅礦的開(kāi)發(fā)，目前已取得了初步進(jìn)展，北京礦冶研究院于

-電積工藝處理這種氧化礦和低品位礦石的生產(chǎn)新流程，具有投資省和生產(chǎn)成本低的最大優(yōu)越性。多寶山銅礦采用這種新工藝開(kāi)發(fā)礦山，是能夠獲得較好的經(jīng)濟(jì)效益和社會(huì)效益 的。 三、鑒于多 *銅礦為大型銅基地，以銅為主，含有多種稀有和貴金屬礦物，需加強(qiáng)試驗(yàn)研究進(jìn)行綜合回收。礦體銅金屬總儲(chǔ)量為 237萬(wàn)噸，其中地表氧化銅礦儲(chǔ)量約 10萬(wàn)噸。本次設(shè)計(jì)的主要對(duì)象是開(kāi)采

6公里簡(jiǎn)易公路從線路平面和縱斷面標(biāo)準(zhǔn)看均已達(dá)到公路要求，只需將部分路段路基拓寬并在全線加鋪泥結(jié)碎石路面，即能保證礦區(qū)對(duì)外的公路運(yùn)輸暢通無(wú)阻。 第三節(jié)建設(shè)方案 一、總體布置原則 *銅礦為大型斑巖銅礦，金屬總量為

aahF 要避免產(chǎn)生生產(chǎn)流程中的迂回運(yùn)輸現(xiàn)象，只有這樣，才能降低生產(chǎn)成本，給企業(yè)增加效 益提供有利條件。 二 、企業(yè)的生產(chǎn)工藝選擇 傳統(tǒng)工藝不但投資大、生產(chǎn)成本高，而且不適合處理低品位的氧化礦，目前國(guó)內(nèi)外在處理低品位氧化礦方面有了很大發(fā)展，采用氧化銅礦石浸出 -萃取 -電積工藝，直接達(dá)到電解銅產(chǎn)品，這種濕法冶金工藝，具有投資孝見(jiàn)效快的優(yōu)點(diǎn)。近年來(lái)在國(guó)內(nèi)特別是云南，氧化銅礦已普遍采用浸出 -萃取 -電積工藝，取得了良好的經(jīng)濟(jì)效益。 *銅礦已對(duì)低品位氧化銅礦進(jìn)行了浸出 -萃取 -電積試驗(yàn)，也已取得了較好試驗(yàn)指標(biāo)。因此，本可行性研究報(bào)告推薦采用礦石浸出 -萃取 -電積生產(chǎn)工藝。 第二章地質(zhì)資源 第一節(jié) 概況

*山礦區(qū)的堆浸 -萃取 -電積工藝試驗(yàn)已取得成功。根據(jù)這些經(jīng)驗(yàn)提出在 *礦區(qū)首先處理氧化礦，給大規(guī)模開(kāi)發(fā)該礦創(chuàng)造條件， 也符合國(guó)家提出的探采結(jié)合政策。 第二節(jié) 礦床地質(zhì) 一、地質(zhì)特征
