SMM7月28日讯：7月27日，嘉能可公布上半年产量报告称，上半年自有铜产量同比下降9%至64.29万吨。主要原因有在Antamina矿山铜锌矿石的产量增加（锌的品味和产量较高），Antamina矿山铜品味的下降， Mutanda矿山的潮湿天气致产量降低，以及Alumbrera矿山寿命接近尾声，矿井的产出与稳定性均下滑。旗下各矿山上半年铜产量明细如下：

非洲

由于2017年早先异常的潮湿天气，Mutanda产量下降。2017年上半年，Mutanda自有铜产量为96,500吨，较2016年同期下降12,400吨(11%)。但由于该工厂在2016年改造升级的完成，2017年上半年钴产量11,200吨，较2016年同期上涨300吨(3%)。

由于在今年4、5月份长达45天的关停，2017年上半年，Mopani（莫帕尼铜矿）自有矿产量为15,000吨，较2016上半年下滑6300吨(30%)。在新的竖井项目完成后，Mopani（莫帕尼铜矿）继续以较低的速度生产。

科亚瓦西

2017年上半年，嘉能可(Glencore)的铜产量为108,600吨，与2016年上半年的比例一致。

安塔米纳矿

该矿目前正在获取更多的铜/锌矿石和较少份额的单一铜矿石。因此，嘉能可的铜产量为70,300吨，比2016年上半年下降了9%，然而锌产量却增加了59000吨，与2016上半年相比增幅为171%。

南美的其他国家

2017年上半年，铜产量为160800吨，比2016年上半年减少24,600吨(13%)，这反映出阿伦布雷拉（Alumbrera）铜品味在降低、井壁稳定性在变差，此处的开采已接近生命周期?；平鸩课?6.3万盎司，下降了8000盎司(5%)，这主要与Alumbrera有关系，部分抵消了安塔帕凯（Antapaccay）黄金品味的提高。

澳大利亚

自有矿产量为116,400吨，比2016年上半年下降了8200吨(7%)，主因在2016年第四季度欧内斯特·亨利公司(Ernest Henry)30%的经济利益被出售。

定制冶金资产

阴极铜产量为259,500吨，比2016年上半年多了17,900吨(7%)，这反映出了巴萨（Pasar）矿的表现更为稳定，在基准期内产能逐渐提升，其冶炼厂的升级和扩张进一步加剧。铜阳极产量为264300吨，与2016年上半年基本一致，这是因为巴萨（Pasar）提高的生产量被Altonorte 冶炼厂and Horne（霍恩冶炼厂）原料品味的降低和定期的停工维修所抵消。

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.
