Why Florrea Xanthate Quality Is Reliable And Guaranteed?

1.  Florrea provide 100% pure xanthate and never mix cheaper xanthate to cheat customers to get orders.

2.  Florrea xanthate is qualified and can be inspection by SGS if required by buyer.

3.  Florrea is ISO9001 certified world leading manufacturer and exporter on xanthate for over 20 years

( Florrea ISO9001 certificate No.:086911Q)

4.   Florrea xanthate is regarded as the world Most reliable quality in the past 10 years.


Why Some Seller Want To Mix Cheaper Xanthate Into Expensive Xanthate?

1. For making more money.

Some xanthate competitors mix cheaper xanthate like sodium isopropyl xanthate(SIPX) or sodium ethyl xanthate(SEX) into PAX to lower price. They supply mixed xanthate to get some illegal profit secretly without telling the buyer in advance.

2. Generally speaking, long chain length xanthate is more expensive than short chain length xanthate.

For instance, 1.1 sodium ethyl xanthate is cheaper than potassium amyl xanthate

1.2 Potassium salt xanthate is more expensive than sodium salt xanthate.

Dear Customers, please open your eyes widely and Buy the right Xanthate .

 

How Do Distinguish And Identify Inferior Xanthate ?

1. traditional xanthate testing method is lead acetate titration method . It can not tell the exact difference.

That is to say, this method can only tell whether it is xanthate and can not analyze whether it has different xanthate inside.

2.Florrea has its typical GC analysis method to tell the exact components of the xanthate.

That is to tell the proportion of different xanthate inside.

 Florrea can assist you to analyze this free of charge.

Application

Florrea Collector Potassium amyl xanthate (PAX) is one of the most powerful flotation collector widely used in mineral processing .Of course it is one of the least selective xanthate. It is relatively unselective.  It has a strong tendency to float iron sulfides unless depressants are used.

 

Florrea Potassium amyl xanthate (PAX)  is used as a good flotation collector for the flotation treatment of all sulfide minerals, Cu/Ni sulphide ore, zinc ores, as well as gold associated with pyrite( gold containing iron sulfides).

It tends to recover all sulfides if circuit pH is maintained between pH 7 and pH 9.

It is most commonly used in the gold industry to recover gold associated with iron sulfides where sulfide grade does not warrant autoclaving.

Florrea Collector Potassium amyl xanthate (PAX) is also used as a scavenger collector following a more selective rougher collector.

It can also get satisfactory results when used in flotation of Lead oxide  ores.

 

 Florrea Collector- Potassium amyl xanthate (PAX) has also been used in based metal flotation where a powerful collector is required while high pH with lime and depressants can limit iron sulfides recovery. This practice has been done on copper-nickel ores, copper ores, and copper-gold ores.


It can be mixed with Potassium ethyl xanthate (Florrea-PEX) and Sodium isopropyl xanthate (Florrea-SIPX) to create a collector with the selectivity of PEX and SIPX and the collecting power of Collector- Potassium amyl xanthate (PAX)

 

Florrea Potassium amyl xanthate (PAX) is also used as Non-selective collectors for flotation of sulphidized oxide ores.

Di Xanthogen Dimer Form Not Stable Above PH 10. 

◆  Dimer is responsible for flotation of pyrite

◆  When using xanthates, pH above 10 is necessary for selectivity against iron sulfides


When xanthates are introduced into a circuit, the use of selective collectors is usually ineffective to improve grade downstream in sequential flotation

Usual feeding methods: POTASSIUM AMYL XANTHATE(PAX )Dissolution Recommendations


Mixing Procedure:

 The dry xanthate should be added to enough water to make the desired concentration of xanthate solution (5 – 20 %).

• It is recommended that the water temperature to be no higher than 20 degrees C to avoid rapid decomposition of the solution.  If water temperature is too cold, dissolution time gets longer.


• Using a hydrometer, complete dissolution can be determined by measuring SG. At 20 degrees C., the specific gravity of a 20% PAX solution is about 1.07. SG curves for various concentrations of xanthate solution at different temperatures are available.

 

• The solubility of POTASSIUM AMYL XANTHATE PAX is 34% at 20 degrees C.  A 20% PAX solution can be made down to about 5 degrees C when the solubility drops below 20%.  The dissolution of PAX is slightly endothermic so the temperature during mixing may experience a slight decrease.

 

• Unless the pellets are extremely hard or oxidized on the surface, dissolution time should be no more than one hour as long as there is adequate mixing power or solution recirculation capability.  The solution does not need to be kept recirculating or mixed after the xanthate is completely dissolved.  Standard mixer types are adequate for the job (either high or low shear).

 

Background Of Xanthate:

Xanthate collectors were introduced in 1925, and are still widely used, especially for easy-to-treat ores where selectivity (especially against iron sulfides and penalty elements) is not an issue. They are usually supplied in the powder or pellet forms and are readily soluble in water, and could be made up to any strength for convenience

in dosing.

 

Xanthate solutions have relatively poor long-term stability and, therefore, are supplied in liquid form only when the manufacturing plant is in close proximity to the use location.

Xanthates are available in a range of carbon chain lengths, generally from C2 to C5. The collecting power generally increases with increase in chain length, but the selectivity decreases. .The activity of the xanthates increases  with increasing chain length of the alky group R; the selectivity decreases  in accordance with increased chain  length. Xanthates are often used in combination with other reagents such as dithiophosphates or thionocarbamates, often added to the scavenger circuit to improve the total recovery. Xanthates undergo hydrolysis in the acid pH range,and are preferred for flotation in alkaline pulp streams. Powder and Pellet form are available with

Purity of  85%  and 90% Min

Xanthates are relatively unstable at low pH and, therefore, are not suitable for flotation in acid circuits

 

Xanthates are water-soluble chemicals that are used primarily in the mining industry. Xanthates can be obtained by reacting an alcohol with carbon disulphide and an alkali such as sodium hydroxide or potassium hydroxide. The alcohols employed are not unique. They can form ethyl, butyl (isobutyl, normal butyl, secondary butyl), propyl (isopropyl, normal propyl) and amyl (isoamyl, normal amyl, secondary amyl) xanthates, in dry forms, such as powder, granules, pellets, tablets or flakes. Xanthate is the common name for chemical reagents used in the flotation of base and precious metals, which is the standard method for separating valuable minerals, such as gold, copper, lead or zinc minerals, from non-valuable minerals, such as limestone or quartz (gangue).


To extract values, conditioned ores are mixed in a solution of water and xanthates and then agitated in flotation cells. Xanthates may be added in liquid or solid form. The xanthates cause the minerals to attach themselves to air bubbles and then float to the top of the flotation cell. As values reach the surface, the bubbles form a froth that overflows into a trough for collection. The residual may be re-used for additional recovery or removed for disposal. Most of the xanthate is consumed in the process. Several flotation processes are required for different ores. Since each ore is unique, there is no standard flotation procedure and no standard grade or type of xanthate used to extract specific values. Each producer has its own grades for xanthate composition, including purity, which is stated as a minimum percentage up to 100 per cent, and moisture. Four types of xanthates (ethyl, butyl, propyl and amyl) are produced in various combinations with sodium and potassium, which are stabilizers in the chemical formula.

 

Formation And Structure

Xanthate salts are produced by the reaction of an alcohol with sodium or potassium hydroxide and carbon disulfide

ROH + CS2 + KOH → ROCS2K + H2O

The reaction involves the attack of the alkoxide salt. For example, sodium ethoxide gives sodium ethyl xanthate. Virtually any alcohol can be used in this reaction. Technical grade xanthate salts are usually of 90–95% purity. Impurities include alkali-metal sulfide, sulfate, trithiocarbonates, thiosulfate, sulfite, or carbonate as well as residual raw material such as alcohol and alkali hydroxide. These salts are available commercially as powder, granules, flakes, sticks, and solutions are available.Chinais a major exporter of granules.


Some Commercially Important Xanthate Salts Include:

  • sodium ethyl xanthate (SEX), CH3CH2OCS2Na,

  • potassium ethyl xanthate, CH3CH2OCS2K,

  • sodium isopropyl xanthate (SIPX)

  • sodium isobutyl xanthate (SIBX)

  • potassium amyl xanthate (PAX)

PAX Safety Recommendations

• Solid xanthates are stable for a long period of time if kept cool and dry.  If exposed to moisture or heat, solid xanthate can decompose to form small amounts of carbon di sulfide which could ignite.  Keep the solid xanthate bags away from water or heat.


• Xanthate solutions being to decompose immediately when they are put into solution. Keeping the solution cool will reduce decomposition time.  Decomposition of the xanthate solution will occur at 20 degrees C, but it will be very slow.  The main hazardous decomposition product is carbon disulfide.  In PAX solutions, the carbon disulfide float to the top.  To avoid problems with carbon disulfide, there should be adequate ventilation in the xanthate solution storage tank to ensure no build up of explosive vapor.  The storage tank and immediate area should be free of ignition sources and grounded to avoid static electricity build up.  The equipment used in and around the storage tank should be explosion proof.

 

• Although the PAX is soluble in water, there may be some sludge developed over a long period of time.  If maintenance work is to be conducted on the tank or piping, make sure the area is thoroughly washed to remove any sludge and explosion tests should be taken prior to any hot work. Cone bottom storage and day tanks are recommended so that any sludge can be sent to the flotation circuit.  Sludge should not plug pumps or affect flotation performance.

 

•Xanthates can be stored and handled in black iron, carbon steel or stainless steel.  Piping can be rubber or plastic.  Copper and brass are not recommended
