Determination of Optimum Parameters for Flotation of

The structure of the xanthates' hydrocarbon (C–H) chain is one of the major factors which affect flotation recovery. The effectiveness and the collecting power of xanthates increase with increasing chain length and vary depending on the chain structure: branched and straight chains. In this regard, the influences of length (2–5 carbon) and structure (straight: normal and branched: iso

Determination of Optimum Parameters for Flotation of

In the case of branched-chain xanthates, the effect of bubble size on flotation recoveries was much more effective than it was with straight-chain xanthates. The flotation recoveries with the addition of MIBC increased gradually from about 35% to over 80% with SIPX and from 40% to over 90% with SIBX.
