How to Select Sodium Isopropyl Xanthate for Flotation

Match the product to the process

Sodium Isopropyl Xanthate is used as a collector for non-ferrous metal sulfide ores, including copper, molybdenum and zinc sulfide ores. It also applies to auriferous iron ore flotation. In a plant evaluating a sulfide collector, identify the ore and the point in the circuit before choosing the grade.

The product is used in rougher and scavenger flotation. A rougher-circuit inquiry should identify the ore and the required active-ingredient threshold. A scavenger-circuit inquiry should also state the existing reagent preparation arrangement, because the granules are prepared in water free of impurities before use. This gives the quotation request a process context without confusing the two grade specifications.

Sodium Isopropyl Xanthate also has uses as a hydrometallurgy precipitator and a rubber vulcanization accelerator. For these applications, name the process function instead of describing the material only as a flotation collector. That distinction helps us match the request to the intended use.

Choose between the 90% and 85% grades

The two grades are separated by active ingredients, free base, and water and volatile matter:

• The 90% grade contains at least 90% active ingredients, with free base at no more than 0.2% and water and volatile matter at no more than 4%.
• The 85% grade contains at least 85% active ingredients, with free base at no more than 0.5% and water and volatile matter at no more than 10%.

Choose the 90% grade when your purchase specification requires the higher active-ingredient threshold or the tighter limits for free base and water and volatile matter. Choose the 85% grade when your process specification is written around that grade's lower active-ingredient threshold and corresponding limits.

Treat the grades as separate purchasing options in trial records, formulations and receiving documents. Put the grade, active-ingredient requirement, free base limit, and water and volatile matter limit in the inquiry. This prevents an 85% and a 90% request from being handled as the same material specification.

Plan the package around handling

We supply Sodium Isopropyl Xanthate in wooden boxes or iron drums. Wooden box sizes are 800 kg, 850 kg and 900 kg. Iron drum sizes are 120 kg and 180 kg.

For a bulk flotation operation, compare the wooden box sizes with unloading equipment and the amount needed for the planned shipment. Smaller handling units can make the iron drum options more suitable for a site that does not receive large boxes. Send the preferred package type and unit size with the grade so we can prepare the inquiry around the intended handling method.

The listed 20-foot FCL arrangements are 20 wooden boxes at 800 kg each for 16 metric tons, 20 boxes at 850 kg each for 17 metric tons, and 20 boxes at 900 kg each for 18 metric tons. Iron drum arrangements are 134 drums at 120 kg each for 16.08 metric tons or 80 drums at 180 kg each for 14.4 metric tons. Compare these unit counts with your unloading space and container plan before selecting the package.

Questions for a precise inquiry

Prepare the quotation request

The 90% grade suits a purchase specification requiring at least 90% active ingredients with tighter free base and water and volatile matter limits. The 85% grade suits the corresponding 85% specification. Both grades can be considered for the listed sulfide flotation duties, while the package choice should follow your unloading method and shipment quantity. Send the process function, ore or material, flotation stage where applicable, grade, package type, unit size, quantity and destination for a quotation.
