nickel laterite processing methods

Worldwide, the majority of nickel is produced from sulphide sources. This is changing, however, with production from lateritic sources expected to rise to over 50% by 2012. This trend results from a combination of the relative availability of nickel laterites (>70% of landbased nickel resources) and the increasing use of hydrometallurgy for the extraction and recovery of metals.

At present, the typical metallurgical methods for processing nickeliferous laterite ores include reduction roasting followed by ammonia leaching and high pressure leaching with sulfuric acid. These methods, however, are mainly used for the recovery of nickel, generate large amounts of environmental contamination. Therefore, in the long term it will be necessary to develop new and more economical processing technologies, so as to achieve the optimum resource utilization.

nickel ore extraction

Nickel laterites are generally mined via open cut mining methods. Nickel is extracted from the ore by a variety of process routes. Hydrometallurgical processes include high-pressure acid leach (HPAL) and heap leach, both of which are generally followed by solvent extraction - electrowinning (SX-EW) for recovery of nickel. Another hydrometallurgical routes is the Caron process, which consists of roasting followed by ammonia leaching and precipitation as nickel carbonate. Additionally, ferronickel is produced by the rotary kiln - electric furnace (RKEF) process. h3>nickel ore processing equipment

As a leading crushing equipment and grinding machine manufacturer, SBM company have developed jaw crusher, cone crusher for nickel ore crushing, ball mill for nickel ore grinding, vibrating screen for sieving and separators for nickel ore separating. We are able to present a variety of sorts nickel laterite ore processing plant equipment in accordance with your precise need.

Nickel ore is crushed under the dimension of 5 inches in principal crushers, then decreased to -1/2" in short head cone crushers. The ore is then ground to -100 mesh in ball mills. Using wet magnetic separators the magnetic ore is separated and additional lowered to -200 mesh inside a ball mill.

Apart from jaw crusher, cone crusher and ball mill, SBM crushing equipment also supplies impact crusher, VSI crusher and grinding machine (Raymond mill, vertical mill, trapezium grinding machine, coarse powder mill, etc.) and optional equipment.
