Mining Chemicals 

Mining chemicals product line includes the traditional sulfide mineral collectors such as xanthates and dithiophosphates, as well as proprietary products based on extensive sulfur chemistry technology.
Our flotation oils such as PHILFLO® flotation oil and ORFOM® MCO flotation oil have application in both sulfide mineral flotation and the fertilizer industry. Our solvent extraction diluents are recognized as the "gold standard" worldwide. Our depressants are based on unique sulfur chemistry. ORFOM® F2 frother is used in both sulfide and oxide mineral flotation.

A brief introduction to mineral processing is provided both as an overview of the art and to acquaint you with some of our basic processing chemicals. The simplified descriptions presented will assist those of you who are proficient in this area with your discussions on this subject with non-technical personnel. Likewise, those not familiar with mineral processing will find this information most helpful in understanding the steps involved in the processing and eventual producing of a metal.

Data sheets are displayed in Adobe® Acrobat® format, and they will open in a separate window. If you need the reader you may download it from Adobe.

Products MSDS TDS Application
ORFOM® SX 7 Solvent Extraction Diluent Solvent extraction diluent for metals, especially copper.  High flash, good phase seperation and rapid extraction kinetics and high selectivity.  Not for use with starter sheets.
ORFOM® SX 10 Solvent Extraction Diluent Solvent extraction diluent for metals.  Good phase break.  Used where low aromatic diluent is desireable.  More effective in chloride leach solutions. Good selectivity.
ORFOM® SX 11 Solvent Extraction Diluent Solvent extraction diluent for metals.  High flash, good phase disengagement.  Very effective in high temperature and chloride leach circuts.
ORFOM® SX 12 Solvent Extraction Diluent Solvent extraction diluent for metals.  Specially treated for rapid phase break in high throughput circuts.  Excellent phase disengagement, rapid extraction kinetics and high Cu/Fe selectivity.
ORFOM® SX 18 Solvent Extraction Diluent Solvent extraction diluent for metals.  Specially designed lower density/lower flash diluent for specialized separations (nanotechnology).
ORFOM® SX 80 Solvent Extraction Diluent Solvent extraction diluent for metals.  Very high performance blend of hydrocarbons yielding high flash, and excellent phase disengagement, rapid kinetics and high Cu/Fe selectivity.  Excellent diluent properties.
MOLYFLO® Flotation Oil Collector for molybdenite in by-product molybdenite recovery plants. Also, a primary or scavenger collector for molybdenite in primary molybdenite ores and in copper-molybdenum bulk flotation processes.
ORFOM® MCX Flotation Oil High performance collector for both primary and by-product molybdenite.  Greatly improves moly recovery in finely ground ores.  Can be used in higher dosages than kerosene/diesel/other oils without froth suppression.
PHILFLO® Flotation Oil Non-polar extender for phosphate and potash flotation.  Improves recoveries by enhancing flotataion of coarse particles at much lower dosages than kerosene, fuel oil and similar oils.
PHILFLO® 50 Flotation Oil Similar to our Philflo Flotation Oil, must midified to a  lower viscosity for differing phosphate/potash ore compositions.  Extender for phosphate and potash flotation.
ORFOM® D8 Depressant Very effective iron, copper and lead sulfide depressant in primary and secondary circuits.  Water soluble.  Effective as a secondary copper depressant.  Removes graphite from sulfide ores.  May not depress chalcopyrite.  pH independent.
ORFOM® MCO Collector Highly effective non-polar collector for molybdenite.  Greater selectivity to moly than other oil products.  Used as the primary collector in primary and by-product molybdenum ores.  Most effective if added to the primary grinding stage.
ORFOM® CO 100 Collector Selective sulfur based collector of base metal and tarnished sulfides, gold and native copper.  Works very well with Molyflo® and Orfom® oil collectors.  Fast kinetics.  Dries/suppresses froth.  Selectivity at low dosages.
ORFOM® CO 200 Collector Highly effective primary collector for sphalerite. Greater zinc recover in some Pb/Zn ores.  Gives a pronounced increase in zinc recovery at a 30% reduction in activator levels.   Used effectivey as a secondary/scavenger collector for base metal sulfides.  Works very well with Molyflo® and Orfom® oil collectors
ORFOM® DNOS (Developmental) High purity sulfur based chemical used in the extraction of palladium from other platinum group metals and for the separation of gold from associated metals.  Use of ORFOM® DNOS leads to enhanced circut performance due to reduced interferences from mercaptans and other sulfur containing species.
ORFOM® F2 Frother Frother produces a medium depth, fast-breaking froth, where a relatively weak, non-persistent froth is desired.  May be of benefit where MIBC is used and a less brittle froth is desired.
ORFOM® F8 Frother Stronger, medium depth, fast breaking proprietary alcohol frother.  Non-persistent froth.
ORFOM® Grade 2 Tannin  

ORFOM® Grade 2 tannin is a modified, cold water soluble, quebracho tannin used commercially in the hydro metallurgical leaching of zinc to reduce the deposition of sulfur on the remaining sphalerite.  This reduction eads to improved leaching and higher recovery.  The tannin also inhibits the deposition of sulfur in the autoclave and flash-cooling tower. Some ores contain high levels of bentonitic clays leading to high pulp viscosity and/or reduced pulp density.  Orfom® Grade 2 tannin is a very effective thinner and can significantly reduce the pulp viscosity due to clay minerals.  Orfom® Grade 2 tannin is beneficial in fluorite (fluorspar) flotation.  It is used to depress calcite flotation leading to improved concentrate grades.
ORFOM® Grade 3 Tannin Zinc leach modifier to reduce sulfur disposition on sphalerite, and subsequent higher recoveries.  Grade 3 Tannin also inhibits the disposition of sulfur in autoclaves and flash cooling towers.  In high bentonite ores, Grade 3 Tannin can significantly reduce the pulp viscosity due to clay minerals.  It benefits fluorite flotation and depresses calcite.
