Florrea 2212 collector has little or no frothing properties. Selectivity

1.This flotation reagent is more selective against iron sulfides in alkaline circuit usually at slightly lower pH than the corresponding xanthates.,

2.It is generally more selective than xanthates in preventing the flotation of iron sulfides

3. Florrea 2212 flotation collector is the most selective collector  among  all  the Florrea 2200 series flotation  reagents dithiophosphate range.

4.Flotation collector Florrea 2218 is a selective collector towards sphalerite

5.Very selective against iron sulfides than other dithiophosphate collectors. Collecting Power

Among All The Florrea 2200 Series Collectors, Florrea 2212 Is The Weakest Collctor Application

1.Like xanthate, this collector is generally used in the flotation of sulphide ores or sulphidized oxide minerals.

2.for flotation of activated Zn sulfides where selectivity against iron sulfides presents a problem.

3.Florrea 2212 flotation collector is mainly used for selective flotation of Cu from Cu/Zn ores where Zn mineral tend to float readily

4.Florrea 2212 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.

5.It does not float lead sulphide.  It is poor collector for galena, making them the ideal choice for selective  flotation of Cu from Pb.

6. The collector being a selective reagent is applicable on easy floating liberated copper sulphide like Skim-Air flotation in the grinding circuit.

Flotation Collector Florrea 2212

7. Being a selective reagent, Florrea 2212 is useful as a rougher collector producing a high grade first concentrate.

8. In the flotation of noble metals the shorter chained dithiophosphate compounds, Florrea 2212   are preferred. For the flotation of free gold the short chained dithiophosphates, Florrea 2212, Florrea 2211 or even Florrea 2216 may be used alone or in combination with each other.

Condition Time and Adding Point staged addition.

Recommended blending with other reagents

Experience Has Shown That A Mixture Below Is Often Better Than Either Of The Collectors Alone.

1. a mixture of alkyldithiophoshate and a xanthate

1.1 In combination with xanthates, Florrea 2212 can provide remarkable advantages in grade and recovery of the concentrates.

1.2 It can be used as the principal collector in conjunction with a xanthate as a secondary or scavenger collector.

2.  a mixture of two dithiophosphates

For optimum recovery a scavenger collector, e.g. a stronger dithiophosphate like Florrea 2211,2214, 2215, and 2216 or a xanthate in conjunction with Florrea 2212 is used.

3.  a mixture of dithiophosphate with thionocarbamate Reagents Preparation

Flotation Collector Florrea 2212 Can Be Added

1. undiluted

2. preferably diluted with clear water to 5-20% solutions. It is good practice to stir before use.


The dosage of Flotation collector Florrea 2212 is usually considerably less than for other sulphide collectors. It varies with the type of ore, usually falling in the range of 20 to 100 grams per metric ton ore.


1. Experience has shown that Flotation collector Florrea 2212   is effective in the pH range of 4 to 12.

2. Because of its selectivity towards pyrite, Flotation collector Florrea 2212 can be used at slightly lower pH than xanthates

3. An advantage of Florrea 2212 in comparison to xanthates is its application in acid pH ranges. Its stability is much higher, particularly in the region of pH 4.
