Hi, Well with the information what i have, i can say that senkol5 is basically a depressor. It is normally used in from flotation process.They are normally used in during the extraction of ore containing suphide. I do not have much knowledge about titanium extraction. But the above mentioned Senkol5 is being used only as a depresser. For more information please visit the below link http://www.freepatentsonline.com/46… and http://www.patentstorm.us/patents/4… Thanks and Best Regards Sasi

According to Scientist, senkol5 is an activator when treating UG2 ore in the Platinum Industries.The flotation experiments were carried out using Senkol 5 (a dithiophosphates) and Variation of collector (Senkol 5). The collectors SIBX and Senkol 5 were supplied by Sen-min. The froth stability response on the addition of CuSO4 as an activator addition have on flotation... of the three depressants on the recovery of the platinum group elements. Depressants are added to flotation circuits to reduce naturally floatable gangue (NFG) present in ores, but under certain conditions have been shown to affect sulphide mineral recovery, particularly guar reducing the recovery of pyrrhotite. Copper sulphate is added to increase sulphide mineral recovery, but may also activate gangue particularly in the presence of dithiophosphate. This has also been shown to vary with ore type. Previous work has shown the usefulness of analysing reagents holistically, decoupling pulp and froth effects and assessing material recovered by true flotation and that recovered by entrainment separately. This work assesses the effect of copper activation on different ores and the ability of two classes of depressants, guar gum (guar) and carboxymethylcellulose (CMC) to reduce this effect and shows that by a depressant dosage of 300 g/t almost all the NFG had been removed from the concentrate. It also evaluates the effect of depressants on the sulphide minerals and shows that pyrrhotite was most affected.The PGMs consist of a family of six greyish to silver-white metals with close chemical and physical affinities and belong to the transition metals of Group VIII in the Periodic Table. Three of the PGM family, namely platinum (Pt), iridium (Ir) and osmium (Os), have high melting points, are very inert and are the heaviest known elements (~22 g/cm3 ). The remaining three PGMs, palladium (Pd), rhodium (Rh) and ruthenium (Ru) are much lighter (~12 g/cm3 .

This information comes from my own knowledge.
