Abstract
The low grade laterite (limonite and saprolite with Ni < 1.8 %) has not yet processed in Indonesia. It uses process hydrometallurgy. The government of Indonesia has been give permission to foreign company to process the low grade laterite with hydrometallurgy (Caron process and HPAL process). Process Caron is used to process laterite Gag island Papua for PT Pasific Nickel USA on 1967. The dramatical increase price of fuel oil after 1973, it become PT Pasific Nickel give up plan and it give back the permission to the government. Process HPAL (High Pressure Acid Leaching) are used to process laterite teluk Weda (Weda Bay) Halmahera for PT Weda Bay Nickel (WBN) Canada and Gag island Papua for BHP Australia. Two companies got the permission on last new era on January 1998. The permission of Gag island Papua is returned by BHP Australia on first year 2009 and the uncertainity when PT WBN Eramet France (PT WBN Canada takes over by Eramet on May 2006) to build HPAL plant. It becomes opportunity to control the part of technology to process the low laterite via research. So the government has bargaining position to increase share at foreign company.
