2. BILCO - 2 Data Reconciliation: BILCO BILCO offers an interactive, quick and accurate way of solving material balance problems in a vast number of applications:  complex flowsheet problems in mineral or food processing plants, chemical or petrochemical plants,  all types of balancing problems for chemical analysis (fitting up to 100% and estimating accuracy of analysis), mineralogy (fitting with chemistry), definition of sampling strategies, mixing and blending, etc. Raw Material WastesConcentrate
