Arutmin owns high-quality coal reserves with high calories and an abundant amount of environmentally- friendly young coal. Arutmin produces a variety of different types of coal at all of our mines. Therefore, Arutmin offers alternative coal products, ranging from high-calorie coal, environmentally friendly low-calorie coal, and specially blended products.
The Senakin Site, Satui Site, and Batulicin Site produce high-calorie quality coal. This type of coal releases a small amount of ash and contains a small amount of high-calorie sulfur. Arutmin is also capable to produce blended coal with certain specifications to meet diverse consumer needs.
Ecocoal is produced at the Asamasam and Kintap Site. Ecocoal is rated environmentally friendly containing a low level of dirt, particularly less dust (5.5% air-dried) and low sulfur (0.3% air-dried), which results in clean combustion. The usage of ecocoal in power plants is capable to meet SOx and NOx disposal regulations without having to install or operate expensive FGD and NOx disposal machines. Ecocoal combustion makes the boiler operate efficiently and accurately.

All guaranteed loading rates per weather working day including Saturdays, Sundays and public holidays, but excluding the major Indonesian holidays.
The guaranteed loading rates shall relate to the parcel size (actual cargo lifted) and not to the size of the vessel or shipment being loaded.
The standard loading rates shall apply to vessels which comply with the regulations and restrictions.
Vessels exceeding the restrictions or not fulfilling the minimum requirements must agree to a loading rate with Arutmin before the vessel's arrival.
Some facilities such as the Coal Processing Plant (CPP) and Port Load Out are equipped at every site. Other facilities such as Overland Conveyor (OLC) are provided at several locations.
These supporting facilities are continuously improved in line with the needs and current technology development. The presence of NPLCT Port has become a crucial milestone towards a smooth process of loading and transporting coal to our consumers
Arutmin implements the best quality management procedures worldwide for our coal production process.
From mining to shipping, the coal runs through sampling and testing at each stage. Metal and magnet detectors are installed in all crushing and washing facilities in the loading and unloading port of the barge and the transport terminal, Port NPCLT.
A dedicated Logistics and Quality Team constantly monitors the coal production process for 24 hours. This is done to ensure the quality of the coal meets the specifications listed in the contract.
Dust control is done by adding 1% moisture to equilibrium dust using the Dust Suppression System (DSS) located at the CPP & Port.
The amount of water for DSS must be maintained, therefore a Sea Water Reverse Osmosis (SWRO) facility is built so the water is constantly available through all seasons.
The analysis of the Coal Quality Scanner on CPP is done instantly every 2 minutes, which helps monitor Good Mining Practice activities and loading accuracy.
Our commitment to providing double protection against metal contamination, such as gear buckets, gear crushers, plates, pipes, bolts, wires, etc., is done by using metal detectors and magnetic separators.
The prevention of non-metal and oversized contamination, particularly oversized coal, is done by installing Screening 150 mm at the end of the OLC process.
This is to ensure a homogeneous size of coal that is shipped. This screening not only prevents non-metal contamination but also metal contamination.
To monitor the homogeneous coal quality, sampling is done using Auto-Sampler.
With a dedicated laboratory, the sample analysis is obtained quickly and precisely during the loading process to the ship.
