Wet low intensity magnetic separation has reached iron recovery above 96 %. As far as flotation is concerned, fatty acid soap from vegetal oil (Hidrocol) as a collector for silicates and apatite was better than amine. Attrition or scrubbing prior to conditioning seems not to affect flotation performance in .

A single stage cleaner flotation using DPG collector in the presence of tapioca dextrin yielded a high grade copper concentrate. As compared to the cleaner flotation in the absence of tapioca dextrin, this resulted in about 70% reduction in the Ni content in the concentrate. Although amyl xanthate exhibited poor selectivity, the presence of ...
