从红土矿中生产镍自新喀里多尼亚的硅镁镍矿的处理开始已有100多年了。然而,直到今天,全世界的镍主要来自硫化矿。纵观未来,作者预测产自硫化矿的镍量变化不大,在今后的10年里镍产量的扩大主要来源于红土矿。因此新的红土矿项目的投资和生产费用将对镍的供应和镍价有较大的影响。此文回顾了红土矿项目的历史并分析了近期不同的红土矿项目和在“图板上”的项目的投资和生产费用,也评估了这些项目的风险,并将讨论这些因素对进一步开发红土矿项目的影响。
More than 100 years have elapsed since the production of nickel from laterite mines from New Caledonia. However, until now, nickel throughout the world has come mainly from sulfide ores. Throughout the future, the authors predict little change in nickel production from sulphide ores, with nickel production largely expanding from laterite mines over the next 10 years. Therefore, the investment and production costs of the new laterite project will have a greater impact on the supply of nickel and on the nickel price. This paper reviews the history of laterite projects and analyzes the investment and production costs of various recent laterite projects and projects on the “board”. It also assesses the risks of these projects and will discuss the impact of these factors on the further development of laterite Impact of mine project.
