Advanced Processing Technology

Transforming nickel ore into battery-grade materials with MPAL technology

MPAL (Modular Pressure Acid Leaching) Technology

Our proprietary MPAL process represents a breakthrough in nickel processing, offering superior efficiency and environmental performance compared to traditional HPAL (High Pressure Acid Leaching) methods.

1

Ore Preparation

Crushing and grinding of nickel laterite ore to optimal particle size for efficient leaching

2

High Pressure Leaching

Controlled acid leaching at high pressure (40 bar) and temperature (250°C)

3

Solid-Liquid Separation

Advanced filtration to separate nickel-rich solution from residual solids

4

Purification

Removal of impurities through precipitation and ion exchange processes

5

Product Recovery

Production of Mixed Hydroxide Precipitate (MHP) or Nickel Sulfate

Technology Advantages

1

Proven Technology, Modified

Based on well-established hydrometallurgical processes, optimized for Indonesian laterite ores

2

Lower Capital Expenditure

Medium pressure equipment is significantly less expensive than high-pressure alternatives

3
