Danafloat™ 262E mineral collector
Danafloat 262E offers good selectivity against pyrite in sulfide flotation and can provide good to 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.
While the product is often used as a single collector, the product can be used in combination with a xanthate reagent in addition or even as a partial Danafloat 262E replacement. Depending on ore mineralogy and flotation circuit conditions,
the Danafloat 262E dosage level is often lower than xanthate on a comparative basis. Danafloat 262E provides greater frothing compared to xanthate.
Depending on water characteristics and chemistry, Danafloat 262E can be diluted in water up to a 10% solution concentration for feeding to the circuit. The product can also be fed to the circuit undiluted. If using a product dilution is desired, because water chemistry can have an impact, stability tests at the target solution concentration is necessary and highly recommended.
Danafloat 262E is normally used in neutral to alkaline conditions (> 6 pH). Typical dosage levels depend on ore feed grades, mineralogies and flotation responses, but typical dosage levels range between 10 to 50 grams per metric ton ore (0.020 to 0.11 lb/T).

Safety and handling
Danafloat collectors are manufactured under the highest quality standards; nonetheless, these chemicals can be hazardous and harmful. Always read and understand the MSDS before handling the product.
Safe handling includes use of safety glasses, splash shield over face, natural rubber gloves and protective clothing. Additionally, avoid inhalation of vapours.
When properly stored, Danafloat 262E has a shelf life of at least 2 years provided the product is stored under the following guidelines:
+ Store the product in a dry and well-ventilated location away from heat and sunlight
+ Use a first in-first out inventory control
+ Avoid freezing
+ Store in plastic drums, polypropylene IBCs/totes, or coated steel drums.
Danafloat 262E is biodegradable. Do not allow product to report to a natural stream as this product can cause ecotoxicity issues.
Most of the collector is adsorbed to the concentrate mineral particles and removed from the system. Any residual in the water phase and adsorbed to minerals that are not floated report to the tailings. Release of the product directly to natural water streams should be avoided.
Danafloat mineral collectors are supplied in a range of containers including plastic drums, coated steel drums, polypropylene IBCs/totes and tank containers having the following net product weights:
IBC containers Net weight: 1,000-1,075 kg
Gross weight: approx. 1,059-1,134 kg
Tank containers approx. 20 mt (44,092 lbs.)
