DNP has developed a patented and novel process for extracting nickel, cobalt and other metals and co-products from nickel laterite deposits utilising nitric acid.
The DNi Process™ is environmentally sympathetic and sustainable – setting it apart from any other hydrometallurgical or pyrometallurgical processes – because it:
- Produces around half the tailings footprint of an HPAL plant of the same capacity (principally due to the recycling of the nitric acid, addition of fewer neutralising agents, and the production of more saleable co-products);
- Produces inert, nitrogen-rich, leach residue (nitrates in processed residue break down to usable nitrogen for plant growth);
- Lowers production costs and efficiently reduces associated environmental issues;
- Delivers leach residue which is able to be dry stacked and returned to the mine;
- Produces magnesium oxide (MgO) without the creation of CO2 – the only process to do this.
By utilising the DNi Process™, DNP’s licensees will be positioned as one of the most environmentally sustainable and lowest cost producers in the global nickel industry. The DNi Process™ offers unparalleled cost efficiency, capital savings and environmental benefits.
According to KPMG: Long-term global nickel consumption is expected to increase at a CAGR of 4.3 percent, from 2,045kt in 2017 to 2,318kt in 2020. During the forecast period (2017–2020). In addition to the growing demand from the stainless steel industry, consumption is likely to be driven by the wide range of applications in other industries, such as vehicle batteries and aerospace equipment. Long-term nickel prices are expected to increase at a CAGR of 11 percent from US$11,155/t in 2017 to US$15,256/t in 2020.
Cobalt is expected to experience a CAGR of almost 7% from 2016 to 2022.
Where will all the nickel and cobalt required to realise this growth come from especially if tailings storage facilities are banned?
