Explanations:The question asks about the mines in Karnataka that are a 100% export unit. To understand this, we need to delve into the geography and mining industry of Karnataka, a state in southern India.
Karnataka is known for its rich mineral resources, particularly iron ore, bauxite, and manganese. Among these, the Kudermukh mines stand out as a significant export-oriented operation. Kudermukh is located in the Western Ghats, a mountain range that runs along the western edge of the Indian peninsula. The mines are situated in the district of Uttara Kannada, in the Western Ghats region of Karnataka.
The Kudermukh mines are operated by the National Mineral Development Corporation (NMDC), a government-owned company. These mines are specifically known for their high-grade hematite iron ore, which is in high demand in the international market. The iron ore extracted from Kudermukh is of such quality that it is entirely exported, making the mines a 100% export unit. This means that all the iron ore mined at Kudermukh is shipped to other countries, primarily to meet the needs of the steel industry in those countries.
The export-oriented nature of the Kudermukh mines is a result of several factors. Firstly, the high-grade iron ore mined here is of superior quality, which is preferred by international buyers. Secondly, the location of the mines in the Western Ghats provides easy access to ports, facilitating the export process. Lastly, the NMDC, as a government entity, has the infrastructure and capability to manage the export operations efficiently.
It is important to note that while Kudermukh is a significant export-oriented mine, there are other mining operations in Karnataka as well. However, the question specifically asks for a 100% export unit, which is a unique characteristic of the Kudermukh mines. Other mines in Karnataka, such as those in Balaghat (Madhya Pradesh) and Khetri (Rajasthan), do not meet this criterion, as they are not located in Karnataka or are not entirely export-oriented.
In conclusion, the Kudermukh mines in Karnataka are a 100% export unit, making them the correct answer to the question. Understanding the geographical and industrial context of these mines is crucial for answering such questions accurately.
