How are integrated steel plants different from mini steel
Complete answer: The Indian iron and steel industry consists of large integrated steel plants as well as mini steel mills. The difference between the two is that integrated steel plants put together the whole process from converting the iron ore to production and manufacturing of steel and finished and semi-finished products.
