The MGB said in March that about 12 new metallic mines – mostly nickel projects – would begin commercial operations this year. "The moratorium on new mining agreements, not just for nickel, was reversed last year to aid pandemic recovery, as it is expected to inject more tax revenue and provide more jobs in the far-flung areas of the country," says Mitzi …

In this paper, the alkaline hydrothermal/water leaching method of sodium hydroxide and laterite nickel ore was used to effectively recover silicon. Alkali/ore ratio of 1.2:1, hydrothermal temperature of 250 °C and holding time of 2 h are the optimum process conditions, and the leaching rate of Si can reach more than 98.8% at this condition.

Pressure acid leaching has been applied to the Caron process to reduce high-energy consuming phases in direct ore leaching. Direct leaching eliminates the need for drying and reduction steps, which then leads to energy savings (Buyukakinci, 2008).The acceptable nickel content in this method is 1–5% (Dalvi et al., 2004).Also, the crushed ore is …

Two broad ore types. Nickel occurs in two broad ore types: laterite (oxide) ores, principally located in tropical and sub-tropical areas, and; sulfide ores, principally located in the temperate to sub-Arctic regions. Major nickel mining locations are depicted in the map – but some of these locations have many operations, and some only one.

We started by asking his views on the common belief that it is difficult to compete with Indonesia for processing plants due to generally lower quality of nickel ore in the Philippines. He replied, "Today, the Philippines exports laterite ores to China, South Korea, and Japan. Most of this laterite ore goes into nickel pig iron plants (NPI).
