SMM7月28日訊：7月27日，嘉能可公布上半年產(chǎn)量報(bào)告稱，上半年自有銅產(chǎn)量同比下降9%至64.29萬噸。主要原因有在Antamina礦山銅鋅礦石的產(chǎn)量增加（鋅的品味和產(chǎn)量較高），Antamina礦山銅品味的下降， Mutanda礦山的潮濕天氣致產(chǎn)量降低，以及Alumbrera礦山壽命接近尾聲，礦井的產(chǎn)出與穩(wěn)定性均下滑。旗下各礦山上半年銅產(chǎn)量明細(xì)如下：

非洲

由于2017年早先異常的潮濕天氣，Mutanda產(chǎn)量下降。2017年上半年，Mutanda自有銅產(chǎn)量為96,500噸，較2016年同期下降12,400噸(11%)。但由于該工廠在2016年改造升級的完成，2017年上半年鈷產(chǎn)量11,200噸，較2016年同期上漲300噸(3%)。

由于在今年4、5月份長達(dá)45天的關(guān)停，2017年上半年，Mopani（莫帕尼銅礦）自有礦產(chǎn)量為15,000噸，較2016上半年下滑6300噸(30%)。在新的豎井項(xiàng)目完成后，Mopani（莫帕尼銅礦）繼續(xù)以較低的速度生產(chǎn)。

科亞瓦西

2017年上半年，嘉能可(Glencore)的銅產(chǎn)量為108,600噸，與2016年上半年的比例一致。

安塔米納礦

該礦目前正在獲取更多的銅/鋅礦石和較少份額的單一銅礦石。因此，嘉能可的銅產(chǎn)量為70,300噸，比2016年上半年下降了9%，然而鋅產(chǎn)量卻增加了59000噸，與2016上半年相比增幅為171%。

南美的其他國家

2017年上半年，銅產(chǎn)量為160800噸，比2016年上半年減少24,600噸(13%)，這反映出阿倫布雷拉（Alumbrera）銅品味在降低、井壁穩(wěn)定性在變差，此處的開采已接近生命周期。黃金產(chǎn)量為16.3萬盎司，下降了8000盎司(5%)，這主要與Alumbrera有關(guān)系，部分抵消了安塔帕凱（Antapaccay）黃金品味的提高。

澳大利亞

自有礦產(chǎn)量為116,400噸，比2016年上半年下降了8200噸(7%)，主因在2016年第四季度歐內(nèi)斯特·亨利公司(Ernest Henry)30%的經(jīng)濟(jì)利益被出售。

定制冶金資產(chǎn)

陰極銅產(chǎn)量為259,500噸，比2016年上半年多了17,900噸(7%)，這反映出了巴薩（Pasar）礦的表現(xiàn)更為穩(wěn)定，在基準(zhǔn)期內(nèi)產(chǎn)能逐漸提升，其冶煉廠的升級和擴(kuò)張進(jìn)一步加劇。銅陽極產(chǎn)量為264300噸，與2016年上半年基本一致，這是因?yàn)榘退_（Pasar）提高的生產(chǎn)量被Altonorte 冶煉廠and Horne（霍恩冶煉廠）原料品味的降低和定期的停工維修所抵消。

African copper

Mutanda’s own sourced copper production of 96,500 tonnes was 12,400 tonnes (11%) down on H1 2016, reflecting reduced throughput, following unusually severe wet weather earlier in 2017. H1 cobalt production of 11,200 tonnes was 300 tonnes (3%) higher than H1 2016, reflecting upgrades to the plant completed during 2016.

Mopani’s own sourced production of 15,000 tonnes was 6,300 tonnes (30%) down on H1 2016, reflecting a 45 day smelter shutdown in May/June. Mopani continues to produce at reduced rates while the new shaft projects are completed.

Collahuasi

Glencore’s share of copper production of 108,600 tonnes was in line with H1 2016.

Antamina

The mine is currently accessing a higher portion of copper/zinc ores and less copper only ores. As such, Glencore’s share of copper production at 70,300 tonnes was 9% down on H1 2016, however increased zinc production of 59,000 tonnes was 171% higher.

Other South America

Copper production of 160,800 tonnes was 24,600 tonnes (13%) down on H1 2016, reflecting lower grades / pit wall stability issues at Alumbrera as it approaches end of life, and expected transition to lower copper grades at Antapaccay. Gold production of 163,000 ounces was 8,000 ounces (5%) down, mainly relating to Alumbrera, partly offset by improved gold grades at Antapaccay.

Australia

Own sourced production of 116,400 tonnes was 8,200 tonnes (7%) down on H1 2016, mainly reflecting the sale of a 30% economic interest in Ernest Henry in Q4 2016.

Custom metallurgical assets

Copper cathode production of 259,500 tonnes was 17,900 tonnes (7%) up on H1 2016, reflecting a more stable performance from Pasar, which was ramping up during the base period, post its smelter upgrade and expansion. Copper anode production of 264,300 tonnes was in line with H1 2016, as improved production at Pasar was offset by lower feed grades and timing of planned maintenance shutdowns at Altonorte and Horne.
