Dyno Nobel subsidiary PT DNX Indonesia has started the operation of its emulsion plant at PT Bukit Suksesindo (BSI)’s Tujuh Bukit gold mine in Banyuwangi in East Java.
The on-site emulsion production ensures that DNX provide a more efficient blasting services.
DNX provides BSI with surface and underground blasting services under a five-year contract.
BSI mine operation manager Shaun Ryan estimated that the company could save up to $US1 million ($1.46 million) a year through DNX’s operating emulsion plant, which improves the efficiency and reduces the production cost of the gold mine.
“We have different emulsion formulas for surface and underground blasting service,” Dyno Nobel Asia Pacific senior vice president Andy Gardner said.
“Since we understand that the underground (mine) is very reactive, we have to use emulsion because it is safer and gives a better outcome.”
This is DNX’s eighth plant since it first started operating in Indonesia over 25 years ago. DNX partners with explosives provider PT Multi Nitrotrama Kimia in providing blasting services for BSI.
Gardner said DNX had put a huge investment in the facility and design the emulsion plant for a long-term operation.
“If we could do a good job, work safely and efficiently, we hope to be here for longer term,” Gardner added.
BSI is conducting underground exploration at Tujuh Bukit. Parent company Merdeka Copper Gold also plans to double Tujuh Bukit’s ore crushing, stacking and processing capacity from four million to eight million tons (3.6 million to 7.26 million tonnes) a year.
The gold mine has a potential mine life of 30 years.
“If that (exploration) is successful, we will be happy for DNX to remain here,” Ryan concluded.
