In practice, it is seen that lower grade graphite having +5% F.C. is blended with higher grades to meet the requirements of beneficiation plant, i.e., +10% F.C. Thus, low-grade ore analysing +5% F.C. also gets used. Tamil Nadu Minerals Ltd (TAMIN) produces flaky graphite from a mine in Sivaganga district in Tamil Nadu.
