Copper Mining and Metallurgy in Ancient India: Archaeological and Textual Evidence
By Mohammad Nazrul Bari
Summary
The history of copper mining and metallurgy in ancient India reveals significant technological and economic activities. Copper, the first metal used after the Stone Age, played a crucial role in agriculture and cultural development, with evidence of its use dating back to pre-Harappan times around 6000 BCE. Archaeological findings from sites like Tal-i-Iblis in Iran and Mundigak in Afghanistan indicate early copper metallurgy, though there is no conclusive evidence of imported technology. In India, sites in Sindh, Punjab, and Mehergarh provide proof of copper use during pre-Harappan and Harappan periods. A notable surge in copper metallurgy occurred during the Harappan era, followed by a decline and later resurgence around 1100–800 BCE, as seen in copper hoards and artifacts from regions like Bengal, Bihar, and Uttar Pradesh. Ancient Indian literature references copper, termed *loha* (red metal) in the Shukla Yajur Veda and *tamra* in the Atharva Veda. The Rig Veda alludes to metals generically as *ayas*, while later texts like the Ramayana and Buddhist Jataka literature mention copper smiths and mining activities. Copper mines were primarily located in Rajasthan’s Aravalli Hills, including sites like Khetri, Alwar, and Bharatpur, with evidence of deep pits, slag heaps, and extensive mining operations. In Jharkhand’s Singhbhum region, mines like Kharsavan and Rekha show ancient shafts and ore extraction techniques. The Kumaon-Garhwal belt in Uttarakhand also supplied copper to the Gangetic plains. Mining methods involved fire-setting to fracture rocks, using chisels and hammers, as described by ancient texts like Kautilya’s Arthashastra and Megasthenes’ accounts.

Conclusion
This research underscores copper's pivotal role in ancient India's technological and cultural evolution, highlighting its early extraction and metallurgical advancements. The study reveals extensive mining activities across regions like Rajasthan, Jharkhand, and the Aravalli hills, with evidence of pits, slag heaps, and sophisticated techniques such as fire-setting. Copper metallurgy, emerging around 5000–4000 BCE, saw significant growth during Harappan times, later declining but resurging by 1100–800 BCE, as seen in artifacts from Bengal, Bihar, and Uttar Pradesh. Literary references in Vedic and Buddhist texts, along with archaeological findings, illustrate copper's cultural and religious significance, from ritual use to everyday tools. The analysis also emphasizes copper's economic importance, as noted by ancient scholars like Kautilya, who linked mining to societal prosperity and defense. Overall, the document positions copper as a cornerstone of ancient
