Purification of synthetic laterite leach solution by ...

2000-7-1  Three-stage scrubbing tests were carried out by contacting the same loaded organic solution three times with fresh aqueous solution containing 5.0 g/L manganese. The A/O ratio was 1:5 to simulate the very low A/O ratio used in practice. The pH values of the scrub solution was 3.5 and no pH adjustment was conducted during the scrubbing tests.

Extraction of Nickel Nickel Ore Mining Mining ...

2019-3-20  The Australian laterite nickel ore is washed by a trommel scrubber. The specifications of the trommel scrubber are: 5m × 11. 9m for limonite, 4m × 7. 4m is used for residual ore. The grit of the first-stage hydrocyclone of laterite mine is fed into the mixing scrubbing tank and then graded into the second-stage hydrocyclone.

Recovery of nickel and cobalt from laterite leach ...

2010-7-1  The scrubbing behaviours of nickel, cobalt, magnesium and calcium were normal, but manganese was not scrubbed well. At pH 5.6, only 15% manganese was scrubbed ( Table 6 ). This result is consistent with the low stripping efficiency for manganese; any Mn(II) which had been oxidised to Mn(III) would be more strongly extracted than nickel, and ...

2015-6-1  A direct solvent extraction (DSX) process to recover nickel and cobalt from laterite leach solutions is potentially more cost effective compared to the traditional precipitation and re-leaching method. A synergistic solvent extraction (SSX) system consisting of Versatic 10 and Acorga CLX 50 in ShellSol 2046 was studied for DSX nickel and cobalt ...

OVERVIEW OF DIAMOND RECOVERY TECHNIQUES

2010-12-7  Scrubbing, crushing and screening constitute the commonly used liberation techniques, but the specific recipe, viz., the extent, the phasing and the type of process action, in each case, is dictated by the ore type and diamond occurrence. There is no standard. It, therefore, requires a good theoretical knowledge of ore dressing techniques
