Danafloat™ 070 mineral collector
Danafloat 070 has strong frothing properties. It is a quite powerful collector and especially in acid or neutral circuits a non-selective product for all sulphides. In alkaline environments, Danafloat 070 is useful for the flotation of copper, silver, gold, lead and zinc sulphides, as in general it does not float pyrite at high pH. Many operators have found that Danafloat 070 together with an alkyl dithiophosphate or a xanthate are the best combinations for optimum grade and recovery. Because of the limited water solubility,
Danafloat 070 should be added to the grinding circuit or the conditioner.
The dosage of Danafloat 070 is wide and varies with the type of ore, usually falling within the range of 10 to 100 grams per metric ton ore.
Danafloat 070 should be used undiluted.
Experience has shown that Danafloat 070 is effective in the pH range of 4-12.

Safety and handling
Danafloat flotation collectors are manufactured under carefully controlled conditions. However, to varying degrees they can be considered harmful or toxic, and therefore before handling this product always carefully read and understand the MSDS for this product.
Danafloat 070 contains 5-10% cresols, and cresols
• may be fatal if inhaled, swallowed or adsorbed through skin
• cause burns
• are extremely destructive to tissue of the mucous membranes and upper respiratory tract, eyes and skin.
Safe handling includes the use of safety glasses, natural rubber gloves and protective clothing. Additionally, avoid inhalation of vapours.
+ Store in a dry and well-ventilated place away from heat and sunlight after the principle “first in/first out”
+ Avoid freezing
+ Store in coated steel drums
Danafloat 070 is biodegradable. The cresols in the product are readily degradable biologically. Cresols show high acute toxicity both towards fish (LC50, 96 hrs, 1-10 mg cresols per litre) and to aquatic invertebrates. The majority of the collector is, however, 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.
