How much is the F.O.B. price of asphalt in Budunyan, Indonesia (with different asphalt content)? How much is it after tax payment in China?

The natural rock asphalt in Butun Island is the asphalt sand in Labari mining area, also called soft asphalt mine, and the hard asphalt mine is mostly in Kapengka area. The difference between soft ore and hard ore lies in the difficulty of mining, and the equipment needed to mine the same amount of hard ore is five times that of soft ore. For example, an excavator can handle 7 trucks 10 ton within the same distance. It is impossible to dig hard ore, because excavators cannot dig hard ore directly. It is necessary to cooperate with four rock drills and a large forklift to cope with the operation of 7 10 ton trucks. In addition, the asphalt of soft ore and hard ore are different in four components, and the modification effect on road asphalt is completely different. The addition of BRA in soft ore processing in Indonesia is 10% of the mixture. The amount of BRA processed with hard ore is 3% of the mixture. Therefore, it is often difficult to tell whether the finished product is soft ore or hard ore, because the products after grinding and dehydration all look the same, and the color depth is related to the dehydration temperature. When the temperature is high, the color of the product is dark, and when the temperature is low, it is brownish black or yellowish. Some manufacturers will add Iranian rock asphalt powder to blacken the products and increase the asphalt content, but the modification effect is far from ideal. Many failed projects in China.

The mining cost of soft and hard minerals is 10 USD/ton, and the asphalt content of Butunyan asphalt is between 23% and 25%. Local mining companies generally do not carry out mineral processing procedures, so the amount of topsoil and interlayer soil determines the asphalt content during mining. The only company that re-beneficiates hard minerals is Julius Mining Company, a subsidiary of DuPont Mining Company, and the roughing cost is about 6-8 USD/ton. At present, the FOB price of soft minerals is $40.
