Mica is a group of silicate minerals that are physically and chemically similar which can be split into thin elastic plates. Mica’s physical, chemical, thermal, mechanical and electrical properties make it a highly sought mineral in electronics, automobiles, paint and cosmetic industries throughout the world. The global mica market valued at USD 567 million in 2018 is expected to reach around USD 727 million by 2025.
The History of Mica Mining in India
Human use of mica dates back to prehistoric times. Until the 19th Century, large crystals of mica were quite rare and expensive due to limited supply in Europe. However, their prices dramatically dropped when large reserves were found and mined in Africa, India and South America during the early 19th century.
According to Indian Forest Act, 1927, mica along with other rocks and minerals found in the forest were called forest produce. In 1947- 48, the production of mica in India was 772 tonnes which increased to about 10,000 tonnes within three years. The rapid growth in production continued until 1960-61 which saw a record production of 28,347 tonnes.

The rapid growth in production continued until 1960-61 which saw a record production of 28,347 tonnes.
However, in 1980, the Forest (Conservation) Act declassified mica as forest produce which led to 700 mines with over 20,000 workers to shut down. The industry, which was facing a recession due to the collapse of the USSR, the biggest consumer of mica, was on the brink of collapse. These events created an economic vacuum where workers dependent on the mica industry were left without any livelihoods.
In 1961 there were 432 legal mica mines operating in Bihar (which included Jharkhand until November 2000); by 1980 the number had decreased to 147, and in 1986 there were only 73 legal mica mines left in the area.
The mica mining industry saw a revival in the early 2000’s, when mica gained mileage as being an environment friendly and natural mineral. The varied chemical properties of mica has led to its increased use in various sectors including construction, beauty, automobile, paints and electronic industry.
