Biomining of sulfidic ores has been applied for almost five decades. However, the bioprocessing of oxide ores such as laterites lags commercially behind. Recently, the Ferredox process was proposed to treat limonitic laterite ores by means of anaerobic reductive dissolution (AnRD), which was found to be more effective than aerobic bioleaching by fungi and other bacteria.
Nickel laterite leaching Outotec is continuously testing and developing an optimum atmospheric leaching process for nickel laterites. In the process, different nickel laterites are leached in several cocurrent stages in atmospheric reactors, depending on ore mineralogy. A viable option for concen
Development of ferronickel smelting from laterite in Japan. Int. J. Miner. Pro cess., 19: 1524. Ferronickel smelters in Japan rely on imported laterite ore and are handicapped by hav ing to transport such lownickel, highmoisture ore from New Caledonia, Indonesia and the Phil ippines.
While nickel laterites hold about 70% of nickel reserves, most ancient nickel production has originated from nickel sulfides. This is now changing due to depletion of nickel sulfide reserves and a gradual increase in the global consumption of nickel every year. Another desired byproduct of mining nickel laterites is their cobalt concentrates ...
Autoclaves are used in mining and minerals processing to extract metals from refractory ore bodies. A typical process for autoclaves is highpressure acid leaching (HPAL), which is often used to extract nickel from laterite ore bodies, but it can also be applied in copper and cobalt production.
Nickel laterites accounted for 60–65% of nickel production in 2017. The Big Three Nickel laterite processing is dominated by three main processes: rotary kilnelectric furnace (RKEF), blast furnace production of nickel pig iron (NPI), both pyrometallurgical processes, and the hydrometallurgical highpressure acid leach (HPAL) process.
nickel production from sulfide mines with more recent laterite projects, thereby leading to an important contribution on the environmental sustainability of a critical metal for modern infrastructure. NICKEL RESOURCES AND MINING Global nickel (Ni) production has increased significantly, including near exponential growth since
PROCESSING OF LOW GRADE NICKEL BEARING LATERITES Boris Krstev, Ilija Ilic University "St Kiril Metodius"Skopje Faculty of MiningGeologyStip Republic of Macedonia Abstract:A combination of current trends and developments may undermine the sulphides supremacy and might tip the balance in favour of laterites for new investigations or projects.

TORONTO, August 5, 2016 – Innovation Metals Corp. ("IMC" or "the Company") is pleased to report on the successful separation of nickel and cobalt from nickellaterite ores at the pilot scale, using its proprietary RapidSX™ process for the lowcost separation of technology metals. The patentpending RapidSX process has previously been used to successfully separate rareearth [.]
"Red Mountain Laterite" is a prospect deposit site discovered in 1955 in the Pacific Mountain System of California, The United States. It is a deposit, located in the Little Red Mountain Area mining district and is not considered to be of worldclass significance. 1 Nickel and chromium deposits are documented at "Red Mountain Laterite."

I think it is one of the reasons why BHPB decided to essentially get out of the nickel business because production of pignickel has put a ceiling price on nickel due to the vast laterite nickel resources around the world, if nickel price goes up production goes up and nickel price comes down! in .
