3-(4-chlorophenyl)-4-phenyl-4,5-dihydro-1H-pyrazole 2-(chloromethyl)-3-methylpyridinehydrochloride 1-(2-bromo-4-methylphenyl)ethanone 3-chloroisoquinoline-4-carbonitrile 5,8-dichloropyrido[3,2-d]pyridazine 2-bromomalononitrile 2-(4-(bromomethyl)phenyl)benzo[d]thiazole 1-(bromomethyl)-3-methoxy-2-nitrobenzene 6-bromo-1H-[1,2,3]triazolo[4,5-b]pyridine 4-iodo-2-((trimethylsilyloxy)methyl)thiazole 6-iodoimidazo[1,2-a]pyridine-3-carbonitrile 2-(4-chlorophenyl)-2-morpholinoacetonitrile 4-chloro-7H-pyrrolo[2,3-d]pyrimidine 4-chloroisothiazole 5-bromo-6-chloro-1H-indole 7-chloro-3H-imidazo[4,5-b]pyridine ethyl3-(4-formylphenyl)propanoate 2,3-dibromobenzaldehyde 1-(5H-chromeno[2,3-b]pyridin-7-yl)ethanone 5H-chromeno[2,3-b]pyridin-5-one 3-chloroisoquinoline-4-carbaldehyde (E)-2-(3-oxoprop-1-enyl)benzaldehyde methyl4-formyl-3-nitrobenzoate 5,6-dimethoxy-2,2-dimethyl-2,3-dihydro-1H-inden-1-one 1-methylbicyclo[4.1.0]heptan-3-one 3-nitro-4-(trifluoromethoxy)benzaldehyde 2-hydroxyquinoline-6-carbaldehyde 2-nitro-3-(trifluoromethyl)benzaldehyde 1-(2-fluoro-4-methoxyphenyl)propan-2-one tert-butyl3-fluoro-4-oxopiperidine-1-carboxylate tert-butyl3-oxopropylcarbamate 2,2-dimethylcyclohexanone 9H-carbazole-3-carbaldehyde N,N-dimethyl-2-oxoacetamide 2-methylpent-4-yn-2-ol 3-tert-butyl-4-hydroxybenzonitrile 4-bromo-2-tert-butylphenol 1,3-dibutoxypropan-2-ol methyl4-hydroxyquinoline-6-carboxylate methyl3-cyano-4-hydroxybenzoate 4-chloro-6-methoxyquinolin-7-ol 3,4-dihydro-2H-benzo[b][1,4]oxazin-7-ol 2-(2-aminothiazol-5-yl)ethanolhydrochloride (R)-ethyl2-chloropropanoate (S)-4-amino-5-(4,4-dimethylcyclohexylamino)-5-oxopentanoicacid (1s,4s)-4-hydroxycyclohexanecarboxylicacid (S)-2-(tetrahydrofuran-3-yloxy)aceticacid (1S,4R)-1-methyl-4-(prop-1-en-2-yl)cyclohex-2-enol (R)-4-(hydroxymethyl)oxazolidin-2-one (S)-4-(hydroxymethyl)oxazolidin-2-one 化工資訊 圣地亞哥10月16日消息，智利國(guó)家銅業(yè)公司(Codelco)已經(jīng)提交有關(guān)老化銅礦Salvador重建計(jì)劃的環(huán)境影響評(píng)價(jià)報(bào)告。該計(jì)劃如果實(shí)施，將大幅提高該礦產(chǎn)量并將其開(kāi)采年限延長(zhǎng)40年。
此項(xiàng)計(jì)劃可能會(huì)將現(xiàn)有礦場(chǎng)從地下礦場(chǎng)轉(zhuǎn)變成露天礦場(chǎng)。Salvador礦自1959年以來(lái)一直在運(yùn)營(yíng)，按照當(dāng)前的狀態(tài)，該礦將在2021年壽終正寢。
智利國(guó)家銅業(yè)公司表示，公司將斥資約10億美元進(jìn)行Salvador礦的重建，并將精煉銅產(chǎn)量從去年的62,000噸提高至90,000噸。Codelco表示，新礦應(yīng)該會(huì)在2021年之前投入運(yùn)營(yíng)。
Codelco是全球最大的銅生產(chǎn)商，公司計(jì)劃明年融資多達(dá)10億美元，以幫助為現(xiàn)有銅礦徹底檢修提供資金。
智利國(guó)家銅業(yè)公司的總裁Juan Benavides本月稍早在接受采訪時(shí)表示，公司擁有一個(gè)在未來(lái)10年內(nèi)耗資390億美元、削減智利旗下銅礦生產(chǎn)成本和提升產(chǎn)出效率的雄心勃勃的計(jì)劃，以實(shí)現(xiàn)在礦石品位不斷下滑的背景下，維持銅礦產(chǎn)出大體穩(wěn)定。
在抑制Salvador礦開(kāi)采成本方面Codelco打起了持久戰(zhàn)。去年Salvador礦銅產(chǎn)量為不到其總產(chǎn)量的4%。
