Danafloat™ 233 mineral collector
Danafloat 233 has little frothing properties. The main application is the flotation of zinc sulphides, e.g. sphalerite and marmatite, where the selectivity of Danafloat 233 towards pyrite is advantageous. Another application is flotation of copper sulphides. In both cases, for optimum recovery a scavenger collector is often needed.
Danafloat 233 can be added undiluted or preferably diluted with clear water to 5-20% solutions. It is good practice to stir before use.
The dosage of Danafloat 233 varies with the type of ore, usually falling within the range of 10-100 grams per metric ton ore.
Danafloat 233 is effective in the pH range of 4 to 12. floating liberated copper sulphide like Skim-Air flotation in the grinding circuit.

Safety and handling
Danafloat flotation collectors are manufactured under carefully controlled conditions. However, to varying degrees they can be considered harmful and therefore before handling this product always carefully read and understand the MSDS for this product.
+ Store in a dry and well-ventilated place away from heat and sunlight after the principle “first in/first out”
+ Avoid freezing
+ Store in plastic drums or coated steel drums
Danafloat 233 is biodegradable. The majority of the collector is tied up with the concentrate and is destroyed in the subsequent processing operations. The remainder is transferred to the tailings. Release into the water systems should be avoided.
Danafloat mineral collectors are supplied in tank containers or plastic drums. If preferred, Danafloat collectors may be supplied in coated steel drums.
