By eliminating the need to heat acid to dangerously high temperatures under hazardous pressures.
With straightforward set-up, our process is flexible and scalable with minimal risk.
The DNi ProcessTM is a simple metal extraction technology. We’re able to process the full lateritic ore profile with complete flexibility. This means we can blend the laterite limonite, saprolite and transition zone in almost any combination. Thanks to the simpler flowsheet and our use of nitric acid. Simple, economical, effective.
The DNi ProcessTM is a greener metal extraction technology. In fact it does not produce wet tailings which require containment dams or dumping at sea.
Our unique patented process consumes very little acid, typically 30-80kg of acid per tonne of ore processed. What’s more, over 99% of the nitric acid used is recovered and recycled. Containing magnesium nitrate, also known as fertiliser, the dry leach residue can be returned to the mine where it encourages the growth of native plants.
Zero waste. Zero toxic tailings. Zero need for deep-sea dumping or poisonous mine dams, the DNi ProcessTM is an environmentally conscious, green alternative.
With significantly lower operating costs, and fast, efficient plant construction.
The DNi ProcessTM makes the extraction of ‘battery-grade’ nickel and cobalt more achievable, more affordable and more profitable. In fact we’re promising to almost double the world’s nickel reserves whilst extracting all saleable metals from lateritic ore (Ni, Co, Sc, Fe, Mg, Al).
We’re empowering industry with a more profitable alternative.
Our simple flowsheet means that plants can be constructed very quickly. In fact, in the hydrometallurgical world, a DNi Process™ plant is the fastest route to market from a standing start.
Take for example the Queensland Pacific Metals’ plant which will be ready to commission just 14-months after breaking ground, and is set to produce 16,000 tonnes of nickel per annum.
This unrivalled timeline positions the DNi Process™ as the only viable method of supplying MHP to meet the expected surge in demand by 2024.
With the DNi ProcessTM, it becomes possible to evaluate the resource in a whole new way. There are more opportunities to profit – not just through treating low-grade ore – but also because the DNi ProcessTM extracts ALL the contained metals. This full utilisation of the mine is something which other processes simply can’t achieve.
MORE METALS = GREATER REVENUE. It also means spreading the economic risk by introducing new markets, and not being reliant on the nickel price alone.
The bottom line? The DNi ProcessTM is more profitable.
