Additional Physical Format: Online version: Kirby, D.E. (Donald E.). Chromium recovery from nickel-cobalt laterite and laterite leach residue. [Washington, D.C.]: U. A roast-leach method was developed by the Bureau to extract nickel and cobalt from domestic laterites.

A concurrent effort was made to recover chromium from either unprocessed laterites or the leach residues. This report characterizes laterites and laterite leach residues.

Metals like nickel, cobalt and copper could be recovery from nickel laterite leach waste by many different processes. Among recovery processes that could be applied are ion exchange, solvent.

It can be seen in Fig. 3a that the leaching ratios of nickel, cobalt and iron are %, % and % respectively from dried laterite ore in H 2 SO 4 liquor. By contrast, after calcination, the leaching of nickel, cobalt and iron from the calcined laterite increase obviously, and Cited by: About 45% of Ni and 37% of Co remained in the leach residue, while 15% Ni and 20% Co were lost in the Mn oxides.

Broader terms: Soils; Sediments (Geology) Filed under: Laterite. Lateritic ore deposits [electronic resource]. The study on iron, aluminium and chromium removal from laterite heap leach solutions by Guise and Castro () showed that % iron, % aluminium and % chromium were rejected at pH and 90 °C by the addition of 50 g/L MgO slurry in the first stage of the precipitation process.

In the second stage of the precipitation process Cited by: 4. High iron (> 35 % Fe) limonitic ores can be treated by high pressure leach using sulfuric acid. An alternative process for the production of base metals (Ni, Co and Fe) from both high and low iron laterite ores is being developed by Process Research ORTECH Inc.

Description Chromium Recovery From Nickel-Cobalt Laterite and Laterite Leach Residue. EPUB

A process for producing an enriched mixed nickel and cobalt sulphide intermediate from a laterite ore slurry containing nickel, cobalt, copper, chromium, zinc, iron and silicon, comprising leaching the laterite ore slurry in a pressure acid leach containing an excess of aqueous sulphuric acid at high pressure and temperature for a time sufficient to extract nickel.

Most chromium-bearing scrap now recycled or refined to recover more valuable elements such as nickel, cobalt, and molybdenum, has significant amounts of chromium that is incompletely recovered. The technology does not now exist to economically separate chromium from complex Ni-Fe-Cr alloys.

The nickel laterite challenge. J modelling and then optimising leach conditions for best nickel (and cobalt) recovery and minimal excess acid additions (i.e.

operating cost). The processing of laterite ores for the recovery of nickel and cobalt has increased as the reserves of exploitable sulphide ores have become depleted. The pressure acid leach process (PAL) has become the preferred option for the treatment of laterite ores.

Atmospheric leach process for the recovery of nickel and cobalt from limonite and saprolite ores. United States Patent Abstract: A process is provided for leaching nickeliferous laterite ores by hydrometallurgical methods at temperatures below the boiling point of the pulp and at atmospheric pressure from which high overall nickel.

Ultra high purity and high purity forms also include metal powder, submicron powder and nanoscale, targets for thin film deposition, and pellets for chemical. A hydrochloric acid hydrometallurgical process was evaluated for Ni and Co extraction from a low-grade saprolitic laterite.

The main characteristics of the process were (i) the application of a counter-current mode of operation as the main leaching step (CCL), and (ii) the treatment of pregnant leach solution (PLS) with a series of simple precipitation steps.

It was found that, during CCL, co Cited by: 3. In spite of the improved awareness of the potential for nickel, cobalt and chromium to cause skin allergy, the incidence of sensitization to them is generally on the increase, especially for nickel.

A diagnostic leach for nickel laterite deportment in all three zones has been. The processing of nickel laterites by high pressure acid leaching (HPAL) typically uses feeds with an average nickel content not less than %–% (cut-off grade %) [] though recently several nickel laterite projects have been revalued with lower nickel cut-off grades based upon the cobalt content of the may also be possible to revalue a low-grade nickel laterite deposit if the.

Laterite - the resulting soil layer, typically red in color due to the presence of iron oxides and hydroxides. Nodular, red to yellow or brown hematite and goethite with as much as 20% Al2O3.

Laterites are formed mostly in the sub-tropical and tropical regions between 25° North and 25° South latitude. Laterites also occur in temperate zones.
