The Development, Problems and Prospects of Indonesian Phosphate

Almost 90 % of phosphate in Indonesia is consumed for natural and manufactured fertilizers, while the rest is used in chemical industries. The consumption of phosphate always increases each year, while Indonesian phosphate production is almost constant at around 75,000 tons annually, except the production in 1988 was 165,000 tons. Due to the limited amount of domestic production, the imported phosphate is increasing each year. Phosphate trading in Indonesia is unique. Some of the domestic production is exported to Taiwan, while phosphate from USA, Morocco, Jordan and Nauru is imported. Indonesian phosphate includes guano phosphate, caving phosphate and small amount of marine phosphate sediment. Problems with Indonesian phosphate include: scattered deposits in difficult locations and a relatively small amount of reserves. Exploitation of phosphate deposits for domestic purpose has a good prospect, mainly because of the rapidly increasing phosphate demand as natural fertilizer or as a raw material for manufacturing fertilizer to support an agricultural sector.
