The company said the decision to shut down the mine, with the process starting on May 1, was the best strategic move as it leaves the orebody intact for future value.
After mining, nickel ores are further processed to upgrade their nickel contents from 1-4% typical of the ores to concentrates with grades in the range 10-20%. Concentration involves crushing the ore and separating nickel-bearing from other minerals using various physical and chemical processing methods. The concentrates are then …
Nickel laterite ore is used to produce nickel metal, predominantly to manufacture stainless steel as well as nickel sulfate, a key ingredient in the batteries that drive electric vehicles. Nickel laterite …
Mining and processing. The ferronickel smelter and refinery are integrated with the mine. Beneficiation plant for the mine consists of a primary and secondary crusher, which is sent to a stacker for ore stockpiling and blending. Process design capacity is 50,000t per annum. Actual capacity depends on nickel grade from the mine.
The country is devising strategies to attract more investors to cater to the growing demand for nickel ore. The Philippines' nickel supply is expected to increase between 2023 and 2025 and stabilise due to mine closures, including the Libjo Laterite Mining Project (2026), the Cagdianao Mine (2025), and ore reserve depletion. 3. Russia

Fire at nickel smelter on Sulawesi island killed 21 workers. There was a strong indication of standard procedure violation and negligence in the implementation of safety requirements that ...
Silica was extracted from nickel laterite ore by hydrothermal process with sodium hydroxide as reaction assistant. The effects of reaction temperature, reaction time, and NaOH-to-ore mole ratio on the extraction rate of silica were investigated by a single-factor experiment. The optimal reaction conditions for the preparation of silica were …
The long-term supply of nickel to society was assessed with the WORLD7 model for the global nickel cycle, using new estimates of nickel reserves and resources, indicating that the best estimate of the ultimately recoverable resources for nickel is in the range of 650–720 million ton. This is significantly larger than earlier estimates. The …
