Most of the mineral deposits found in North-East India remain unexploited due to inadequate knowledge on their status, economic viability, and requisite mining technologies. The aim of this study is to characterize the multimetallic magnetite mineral deposit from the Nagaland area in India. The quality of iron ore was evaluated to establish its suitability as a raw material for iron production. Detailed studies were conducted to establish the composition and properties of the samples. X-ray diffraction (XRD), X-ray fluorescence (XRF), electron probe micro-analyzer (EPMA), and petrographic microscopy techniques were employed in the investigation. Shatter and tumbler test was performed for analyzing the mechanical properties of the ore. XRD studies indicated that magnetite is the major mineral with low amounts of martite, maghemite, and quartz. XRF/EPMA results indicated that magnetite contains 35–65 wt.% of iron and 1–5 wt.% of chromium. It also confirms the presence of Ni and Al up to 1 wt.% and Si up to 6 wt.%. Chromite-rich ore contains up to 30 wt.% Cr and 15–20 wt.% of Fe.

由于对印度东北部的地位，经济生存能力和必要的采矿技术缺乏足够的了解，因此大多数印度东北部的矿床尚未开发。这项研究的目的是表征印度那加兰邦地区的多金属磁铁矿矿床。对铁矿石的质量进行了评估，以确定其是否适合用作生产铁的原料。进行了详细的研究以确定样品的组成和性质。在研究中使用了X射线衍射（XRD），X射线荧光（XRF），电子探针显微分析仪（EPMA）和岩石显微技术。进行了粉碎试验，以分析矿石的机械性能。X射线衍射研究表明，磁铁矿是主要的矿物，其马氏体，磁铁矿和石英含量较低。XRF / EPMA结果表明，磁铁矿含有35-65 wt。％的铁和1-5 wt。％的铬。还证实了存在高达1wt。％的Ni和Al以及高达6wt。％的Si。富含铬铁矿的矿石包含高达30 wt。％的Cr和15-20 wt。％的Fe。
