The quality of limestone composite in the mine by Company’s is CaO> 43% and RCO3> 78%. The value of Cut of Grade (COG) which is still categorized by ore is CaO at 30% and RCO3 is 70%. The results of this study indicate the assumption of the selling value of limestone with composite quality of Rp. 48,500 per ton with a maximum production rate of 2 million tons per year, still provides eligibility criteria for all investment parameters calculated showing IRR 13.72%, NPV (+) Rp 5,111,313,765.-, PBP for 6.42 years. The effect of increasing or decreasing cement price assumption and operational cost ± 1.5%, will give a significant effect on the rate of return on the calculation of this study.]]>
