Archaeological sites in India, such as Malhar, Dadupur, Raja Nala Ka Tila and Lahuradewa in the state of Uttar Pradesh show iron implements in the period between 1800 BCE-1200 BCE. Sahi (1979: 366) concluded that by the early 13th century BCE, iron smelting was definitely practiced on a bigger scale in India, suggesHistory of metallurgy in the Indian subcontinent

Metallurgy of Ancient Indian Iron and Steel SpringerLink
The iron and steel trade from India declined and the ancient method of extraction and processing became extinct by the beginning of the twentieth century. The British in India made attempts to work on iron ores on a large‐scale by modern methods. Several iron and steel works were set up in the country.Now, we are going to take another class of alloys, which combine, ferrous and non- ferrous. These are ferroalloys. Like there are alloys, which contain iron and nickel, called as ferronickel, similarly, like ferromanganese; (PDF) Non-Ferrous Extractive Metallurgy
