O-Isoproppyl-N-Ethyl Thionocarbamate

• Isopropyl Ethyl Thionocarbamate offers good selectivity against pyrite in sulfide flotation and can provide excellent flotation response to various copper minerals, including but not exclusively, chalcopyrite, bornite, chalcocite and

covellite.

• Other applications include copper activated sphalerite, tetrahedrite and, depending on ore mineralogy, gold ore

flotation. The mercaptan component makes this product a good metallic element collector and often enhances the

flotation of tarnished and slightly oxidized minerals.

• While the product is often used as a single collector, a xanthate reagent can be used as a partial replacement, and depending on mineralogies and flotation circuit conditions, the dosage level typically is lower than xanthate on a

comparative basis. It has a greater frothing property compared to xanthate.

• Because Isopropyl Ethyl Thionocarbamat is relatively insoluble, water dilutions are not stable. Consequently, the

product should be fed to the circuit undiluted. It has sufficient solubility particularly under normal sulfide slurry

conditions that the adsorption kinetics are relatively fast.

• Because of their high collecting power in moderately alkaline circuits, and their high selectivity against iron sulfide minerals, the preferred rougher flotation pH for these collectors is usually in the range of 8 to *0, compared to the typical range of *0 to *2 required with other collectors. Similarly, in the cleaner circuits, the pH required is lower than that necessary with other collectors.

• They are stable hydrolytically in a wide pH range, and generally enhances the recovery of precious metals.
• Typical dosage levels depend on ore feed grades, mineralogies and flotation responses, but typical dosage levels
range between *0 to *0 grams per metric ton ore .
