Mining: Ammonium Nitrate Solution (ANSOL) implementation at PT Kaltim Prima Coal (KPC)

At PT KPC in Indonesia, the Group ANSOL replaced traditional Ammonium Nitrate (AN) Prill in emulsion manufacturing. This transition has delivered multiple benefits for customer safety, efficiency and sustainability outcomes. By eliminating the energy intensive dissolution stage, ANSOL has reduced fuel use during processing by up to 25% and cut water consumption at the site by up to 69%. The move also removes the need for chemical coating agents and eliminates waste from bulk AN bags, directly supporting waste and circularity objectives. Operationally, ANSOL improves emulsion stability and product quality, is not prone to caking during temperature changes and reduces emulsion manufacturing time by up to 25%, freeing up capacity and improving plant reliability.

ANSOL is also contributing to safer operations. Reduced handling and the removal of moving machinery in raw material transfer lowers the risk of spillages and associated incidents, while a more stable and predictable emulsion supports consistent blast performance. Combined with a reliable local supply chain, this solution demonstrates how innovation in raw material form can address safety, environmental and supply risks at once.
