Because flotation can maximize the enrichment of gold into sulfide concentrates. According to the nature of high sulfide gold ore, sulfide suppression flotation process is preferred. Thesulfide suppression flotation process preferentially recovers gold, which aims to maximize the recovery of gold and sulfide. Predetermined grinding size, chemical system and the process of gold processing test.
The results demonstrated that co-grinding with sulfur solely had the best flotation performance at the value of 0.5 wt.% and it was attributed to the possible existence of S O bonding on copper oxides surfaces. In addition, adding magnesium nitrate salt, magnesium powder, iron nitrate salt and aluminum powder as additive associated with 0.5 wt% sulfur intoball millingcaused the flotation improvement …

Theflotationtailings are ground and then floated, which can increase theflotationrecovery rate. In most cases, the cyanide method is more commonly used in quartz vein type goldore. The main considerations are the fineness of theore grinding, the concentration of cyanide in the slurry, and the leaching time.
Here are four processes used in the frothflotationprocess of copper-nickelsulfide ore. 1. Differentialflotationor partial differentialflotationprocess. When the content of copper is much more than nickel in theore, this process can be used to separate the copper as the single concentrate.
