KPI Si.Mn based on local ores of both Comilog & NGM

Technical KPI calculations, power formulas, and grade specifications based on local ores of both Comilog & NGM.

Operating Formulae

Day Power Generation Formula

22.5 x .78 PF x .97 LF = 17 MWH x 24 hrs = 408 MWH/day

Day Production Formula

Specific Power @ 3.8 = 107 MT x 2 Furnace = 214 MT/day
