XANTHATES

Senmin manufactures a complete range of varying hydrocarbon chain lengths, namely ethyl, propyl, isobutyl and pentyl.

These products find their application across the entire range of ores beneficiated by flotation, namely base metals, platinum ores etc.

Senmin is fully back integrated with respect to the local sourcing of the raw materials required for the manufacture of the aforementioned xanthates.

All xanthates, with the exception of potassium amyl (PAX) and potassium normal butyl xanthate (PNBX), are available both as pellets and liquids (only in South Africa) as the sodium salt.

Packaging is 25kg and 850kg bulk bags.

The Technical Manager responsible for the product range and the issuing of MSDS and TPD sheets is Mr Richard Bergman.

SENKOLS

In an effort to improve the selectivity of xanthates a series of co-collectors has been developed and are manufactured locally by Senmin.

Senkols comprise of dithiocarbamates and formulations with xanthates dithiophosphates of dithiocarbamates and are synthesized from amines and alcohols respectively. Properties can be tailor-made to suite the application by varying the hydrocarbon chain length.

Senkols are used both as partial and full replacement of xanthate such as is the case with Senkol 821, resulting in improved metallurgical performance in respect of grade and/or recovery.

Dithiophosphates exhibit frothing properties which is not the case with dithiocarbamates.

The following is a list of Senkols currently commercially proven, namely Senkol 3, 5,8, 9, 65, 294, 295 and 821

Packaging is drums, 1000kg IBC’s and bulk tankers of tons.

SENFROTH

Senmin manufacturers and formulates a wide range of water soluble and in-soluble frothers.

The water soluble Senfroth range is primarily manufactured from propylene or ethylene oxide using a wide variety of initiators to achieve different properties such as molecular weight.

The water in-soluble products are dimethylphalate based.

Formulated frothers are customized to meet specific requirements of the client such as easy breakage in the launder, persistence in the cleaner circuit, targeted bubble size distribution in the flotation cell to maximize particle/bubble contact etc.

Packaging is in 200kg drums, 1000kg flowbins and in bulk deliveries via tankers.

Please contact, The Technical Manager Mr Richard Bergman responsible for the product range and the issuing of MSDS and TPD sheets for more information.

SENDEP

The majority of minerals present in ore bodies beneficiated by flotation consists of unwanted material classified as gangue.

Gangue minerals tend to be naturally hydrophobic and if not suppressed, made hydrophilic, will report to the froth phase thus preventing the collection of the valuable minerals.

Senmin has a state of the art production facility in Sasolburg, South Africa capable of processing any naturally occurring feedstock such as galactomannan, cellulose, starch etc.

The aforementioned polysaccharides are converted into depressants that impart the hydrophilic properties to gangue minerals thereby improving the overall selectivity of the beneficiation process.

The Sendep range currently commercially available and in use by a vast number of concentrators are Sendep 348, 369, 30D, 30E, 30F and 300.

Packaging is in 25kg, 700kg and 1000kg and in bulk tanker loads of 30 tons.

Please contact the Technical Manager, Mr Richard Bergman, who is responsible for the product range and the issuing of MSDS and TPD sheets for more information.

SENFLOC

In a world where water is fast becoming one of the most valuable resources, it is more and more incumbent that water is conserved and recovered.

This is achieved through the treatment of the tailings of mining operations with polyacrylamides being dosed in thickeners.

Senmin manufactures the full range of anionic and nonionic Magnafloc® and Senfloc™ polyacrylamides utilizing a, first time in the world on an industrial scale, bio process where the advantages of reduced electricity consumption and close to zero effluent has been achieved compared to the current practise utilizing copper catalysts.

The aforementioned has gone a long way in assisting both Senmin and AECI achieving their respective green chemistry goals.

These products are manufactured in anionic and nonionic forms by polymerisation and copolymerisation of sodium acrylate and acrylamide. Composition can be varied from completely anionic through to totally nonionic with all variations in between, thus producing a spectrum of products with each product having a different performance efficiency under various conditions of solid-liquid separation.

Packaging is in 25 kg, bulks bags of either 700 or 800 kg and in bulk deliveries via tankers.
