DENOL-30 is used as a silver promoters in Lead, Zinc Floatation.

Properties Suppliers
Danafloat 067

Danafloat 067 is a water soluble salt of aryl dithiophosphoric acid. It has a light frothing characteristic and is especially useful where a fast, selective and active collector is required and no conditioning of the collector with pulp is possible. The dosage of Danafloat 067 is wide and varies with the type of ore, usually falling within the range of 10 to 100 grams per metric ton ore. It can be added undiluted or preferably diluted with clear water to 5-20 % solutions.

Properties Suppliers
Danafloat 068

Danafloat 068 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 are in the flotation of galena and copper activated sphalerite, tetrahedrite and gold ores. The product can be used in conjunction with xanthate or as a replacement and, depending on mineralogies and flotation circuit conditions, this product may be stronger than xanthate in which case the dosage will be lower than xanthate. It has frothing capabilities so often frother dosages are reduced when switching to this product. It can be fed to the circuit either undiluted or as a solution. Before deciding to dilute the product, because water chemistry can have an impact, stability tests at the solution concentration desired are highly recommended. It is 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.

Danafloat 070

Danafloat 070 is an aryl dithiophosphoric acid. It 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, it 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. It should be used undiluted.

Properties Suppliers
Danafloat 123

Danafloat 123 is useful as a rougher collector producing a high grade first concentrate. For optimum recovery a scavenger collector, e.g. a stronger dithiophosphate or a xanthate in conjunction with Danafloat 123 is used. It is very selective towards pyrite and other iron sulphides and is therefore used in the flotation of copper sulphide mineral and Cu-activated sphalerite, particularly in the presence of pyrite. It does not float lead sulphide. The collector being a selective reagent is applicable on easy floating liberated copper sulphide like Skim-Air flotation in the grinding circuit. It can be added undiluted or preferably diluted with clear water to 5-20% solutions to better control the dosage. The dosage of Danafloat 123 varies with the type of ore, usually falling within the range of 20 to 100 grams per metric ton ore. It is effective in the pH range of 4 to 12. Because of its selectivity against iron sulphides, Danafloat 123 can be used at lower alkalinity than xanthates.

Properties Suppliers
Danafloat 233

Danafloat 233 is an aqueous solution of dialkyl dithiophosphate. It 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. It 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.

Properties Suppliers
Diacetyl Dioxime

Dimethylglyoxime is used in the analysis of palladium or nickel.It is used as a solution in ethanol.

Properties Suppliers
Diethylenetriamine

Diethylenetriamine is an analogue of diethylene glycol. It has similar chemical behavior as ethylene diamine and has similar uses. It is a weak base and its aqueous solution is alkaline. It is used in oil industry, as a solvent for sulfur and extraction of acid gas. Mixed with unsymmetrical dimethylhydrazine it was used as Hydyne, a propellent for liquid-fuel rockets. It is a polyamine used as a depressant for pyrrhotite and arsenides in copper and nickel mineral flotation.
