Abstract
 Administratively, the research area is included in North Morowali Regency, Central Sulawesi Province, Java which 49 S zone with UTM (Universal Transverse Mercator) coordinates 9152800 – 400800 - 406800 mE an of ​​± 54 km2 (9 km x 6 km). ). One factors that influence formation laterite nickel deposits source rock. The purpose this to focus on characteristics original rock, namely ...

The carbothermic co-reduction of nickel laterite ore and red mud realized the simultaneous reduction nickel, iron in ore, at high efficiency. Nickel were recovered form ferronickel. size characteristics ferronickel particles grindability products are essential for obtaining good technical indicators. influence conditions on particle relative was investigated by a test, analysis, determination. ...

Following QA/QC procedures, portable XRF (p-XRF) field tests were performed on borehole samples from nickel laterite deposits and the results compared with lab-XRF results. To verify reliability accuracy of obtained by p-XRF in field, certified reference materials prepared as glass beads analyzed together samples. The showed that overall contents each element generally lower wet than pulp sampl...

Abstract In consideration of the abundant moisture limonitic nickel laterite mined, it is essential to determine whether self-possessed after pre-dried appropriate for sintering. Thus, based on characterization laterite, influence its sintering performance was expounded by sinter pot tests and relevant mechanism revealed systematical analyses granulation properties mixture, thermodynamic condit...

Nickel is an important strategic metal in the world. As sulfide ore containing high-grade nickel increasingly depleted, laterite ore, which rich resources, has attracted people’s attention. In this paper, reduction roasting-magnetic separation process used to study method of preparing ferronickel concentrates from low-grade under action composite additives (Na2CO3 and CaF2). The research result...

Nickel plays a critical role in the mining industry. However, presence of nickel primary source sulfide minerals is decreasing. Focus has since turned to laterite ore, which contains up 80% Ni metal. The purpose this study was optimize leaching using sulfuric acid and conduct kinetic analysis discover mechanism that best controls process. To operating conditions, response surface method (RSM) w...
