Nickel & Cobalt Products

The Piauí Nickel Project produces a high purity nickel and cobalt mixed hydroxide product.

Mixed Hydroxide Product (MHP) is an intermediate that can be used to produce nickel precursors for Li-ion battery cathodes for EVs or to feed the tradition nickel uses of stainless steel and alloys.


Nickel-containing materials play a major role in our everyday lives, with it being used in over 300,000 consumer products – food preparation equipment, mobile phones, medical equipment, military, transport, aerospace, buildings, power generation – the list is almost endless. They are selected because – compared with other materials – they offer better corrosion resistance, better toughness, better strength at high and low temperatures, and a range of special magnetic and electronic properties.

Almost two thirds of total nickel production is used in stainless steels today with 15% of production feeding precursor production for cathodes in electric vehicle batteries.

Nickel and cobalt are also critical components in re-chargeable batteries found in cell phones, laptops and, increasingly in electric vehicles and energy storage units.

Cobalt is also used in magnets, for such applications as wind turbines, and in a variety of other areas including ceramics, pigments, catalysts, drill-tools and so called ‘super alloys’ found in jet engines.

The Nickel Institute’s publication “Nickel in Society” outlines in the current use of nickel in much more detail.
