摘要:
随着世界上硫化镍矿资源日趋枯竭以及未来镍需求量不断增长,红土镍矿将成为未来镍的主要来源，因此红土镍矿的有效处理以及高效利用对我国的经济建设有着极大的意义。红土镍矿由于其具有储量丰富、易开采、便于运输等特点，已成为研究开发的热点。本文主要从不同矿层的红土镍矿角度,介绍了当前不同红土镍矿冶炼方法和技术，概述了不同矿层的红土镍矿及其适用的冶炼工艺，分析了不同红土镍矿处理工艺的优势与不足，实现不同类型红土镍矿的综合利用。
Abstract:Recently, the depletion of nickel sulfide resources barely meet the increasing demand and laterite nickel ore gain a special attention as the main source of nickel in the future. Even laterite nickel ore has become a hot spot of research due to its rich reserves, easy mining, and convenient transportation, the effective treatment and efficient utilization of laterite nickel ore is still very appealing. In this article, we mainly introduces the smelting methods and technologies of different laterite nickel ore from different ore layers, summarizes the laterite nickel ore of different ore layers and their applicable smelting processes, analyzes the processing technology of different laterite nickel ore, and realizes different types of laterite comprehensive utilization of nickel ore.
