Direct Nickel (DNi), an Australian company that includes the CSIRO as one of its shareholders and research partners, has partnered with PT Antam (Persero) Tbk to develop a DNi Process Plant in Indonesia and is poised to take full advantage of the Indonesia ore export ban that took effect this month.
As nickel concentrate will not be subject to export bans, Direct Nickel expects a high level of demand to fill the gap in global markets created by the ban, particularly in China.
A feasibility study has commenced on a DNi Process Plant at Antam’s Buli operation in Halmahera, Indonesia. The study, which is led by a joint Antam/DNi team, is expected to be completed early in 2015.
Annual nickel ore exports from Indonesia previously represented up to 20% of global supply. Current stockpiles are forecast to be depleted during 2014 and Direct Nickel is uniquely positioned to supply nickel concentrate into the markets impacted by the export restrictions. Nickel prices are already rising following Indonesia’s implementation of its ban on exports of unprocessed ore.
Direct Nickel positioned itself to capture this opportunity by initiating discussions with Antam as early as 2009 when the export ban was first announced. Since then, Direct Nickel has built on its presence in Jakarta through the formation of a local subsidiary PT DNi with Indonesian partners, with the establishment of a Jakarta office and signing cooperation agreements with Antam in 2012 and 2013.
DNi CEO Russell Debney says the export ban has made Indonesia even more attractive as an investment destination for the company. “It is clear that the Indonesian government intends to stimulate the growth of the processing industry within the country. Companies, such as Direct Nickel, that are able to produce nickel concentrate efficiently and competitively are set for a material re-rating as a result of this important development. We could not have asked for a better time to start planning our first commercial plant in Indonesia with the major industry group Antam.”
DNi and ANTAM intend developing a process plant in Indonesia in Halmahera, adjacent to Antam’s new ferronickel smelter which is under construction. Antam is a diversified mining company and Indonesia’s largest nickel miner and already operates ferronickel processing facilities in Sulawesi.
The Buli Plant will be the first commercial processing plant to utilize the revolutionary processing technology developed by DNi and is likely to annually produce 10-20,000 tonnes of nickel in concentrate.
The DNi Process is expected to be very competitive in the Indonesian environment as well as offering low environmental impact due to the recycling of nitric acid used in the process.
The revolutionary process has been developed over the last seven years and successfully demonstrated over the last year at DNi’s test plant in the CSIRO’s Australian Minerals Research Centre in Perth at a scale of 1 tonne of ore per day. The test plant operation was completed successfully in December 2013 after 12 months of operation, with final reports being prepared. Most of the ore for this demonstration was sourced from Antam’s Buli operation.
The demonstration has shown the process has very high recoveries of nickel, and other valuable by-products such as cobalt, iron ore and magnesium oxide.
Indonesia is the world’s largest exporter of unprocessed nickel laterite ore, and the main supplier to China’s rapidly growing nickel pig iron industry. The ban will have a material impact on the world’s nickel industry, impacting industries reliant on the metal including the Chinese stainless steel sector.
Ahead of the ban on exports, consumers in China built stockpiles of nickel laterite ore to offset supply interruption. These are expected to be eroded over the next six months, further tightening the nickel market and with the nickel price continuing to increase. Indonesia has until now been China’s supplier of choice due to its abundant nickel laterite resources, proximity to China and very high nickel grades.
