Indonesia’s only smelter-grade alumina (SGA) refinery PT Well Harvest Winning (WHW) churned out over 2 million metric tons of the aluminium precursor since commencing operations in June 2016. So said a corporate representative in an interview with domestic media last week.
Well Harvest Winning public relations executive Hen Roliya told The Jakarta Post on Friday that 98.5 percent was sold and shipped overseas, and the remainder was tendered to the state-owned energy firm PT Inalum, which uses it to produce its own primary aluminium.
“We have been selling [our SGA] to Inalum, which is 1.5 percent of our production. […] And there will be a increase of sales to Inalum in November to 28,000 metric tons of SGA,” Roliya elaborated.
She said that Inalum subsequently purchased 31,179 metric tons of smelter-grade alumina in December and the following February.
“We have been importing alumina to date to produce aluminum ingot,” said Inalum managing director Oggy A. Kosasih in a previous press statement. He went on to say that, in order to produce 250 thousand metric tons of primary aluminium, the firm required twice that amount of smelter-grade alumina.
Though it has a ready supply of alumina, Inalum is planning to open its own refinery within the next several years. The firm plans to invest US$850 million in the project, with an anticipated commissioning date of 2021.
Well Harvest Winning is a joint venture among majority partner China Hongqiao Group Limited, Jakarta’s PT. Harita Jaya Raya, and Singapore Winning International Group.
