Pelletizing Aids in Upgrading Low-Grade Nickel Laterites

Pelletizing Laterite Fines. Interestingly, pelletizing is assisting in the recovery of nickel from laterite ores in another way as well: nickel dust recovery. Laterites tend to exhibit a high fines content. As a result, a significant amount of fines are produced during initial handling and processing.

Processing of Nickel Laterite Ores on the Rise

While sulfide nickel ores are processed via upgrading to concentrates and then smelting, this approach is not applicable to laterite ores. A variety of approaches are available to process nickel laterite ores, with the most prevalent approaches explained below. The method(s) chosen is dependent on the composition of the unique ore source.

Nickel Cobalt – A-Cap Energy

The Wiluna region was first explored in the late 1960’s for nickel sulphides (Mt. Keith style). In the early 1970’s the Wilconi area was drilled for nickel laterite mineralisation and subsequent explorers focussed again on the nickel sulphide potential until 2005, when the then operator Agincourt Resources Ltd (Agincourt) drilled the deposit for nickel laterite.

SOLVENT EXTRACTION PROCESS FOR THE RECOVERY

Low-grade laterite which contains nickel lower than 0.5 % is difficult to beprocessed using pyrometallurgy. One method which isable to solve this problem is solvent extraction. In thisstudy, a solvent extraction process using batch recycle method s has been successfully applied to separate nickel and cobalt from low-grade laterite.
