What Is Xanthate?

Sodium Isopropyl Xanthate (SIPX), also called Proxan-Sodium,  is a type of xanthate salt customized chemically for particular utilities. So, to make a general understanding of Iran Sodium Isopropyl Xanthate, first, we should learn about xanthate in general.

The word “xanthate” typically refers to a salt containing the chemical formula ROCS 2M+ (R = alkyl; M+ = Na+, K+), which makes them metal-thioate/O-esters of dithiocarbonate. The mining sector mainly employs these chemicals because they hold various properties like water solubility. By combining alcohol with carbon disulfide and an alkali, such as sodium hydroxide or potassium hydroxide, xanthates can be produced, and Xanthation is the procedure’s name. The alcohols used in such a process are not exceptional.

Chemists can create Mineral Processing Chemicals like 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. It is also vital to bear in mind that xanthate is a common term referred to chemical agents employed in the flotation of base and precious metals. It is the primary process for separating valuable minerals, like gold, copper, lead, or zinc, from non-value minerals, such as limestone or quartzite.

What Is Sodium Isopropyl Xanthate (SIPX)?

Carbon, hydrogen, oxygen, sulfur, and sodium make up the chemical SIPX, a type of xanthate salt widely used in industry. Sodium isopropyl xanthate, or SIPX, holds the chemical formula of (CH3)2CHOCS2Na. The powder form of Iran SIPX is a light yellow color with unique properties like water solubility and mild disagreeable odor. The pellet form of this chemical compound also holds a Yellow to green color and a sulfurous smell. Like all xanthate compounds, SIPX hydrolyzes gradually in the presence of the explosive gas carbon disulphide, which causes moisture to form.

It also worth mentioning that the acetone technique is employed to determine the active xanthate content. The active xanthate concentration is at least 84 per cent on a dry weight basis. High-quality raw materials were used in the manufacturing process, and parts that would have compromised the product’s selectivity were left out. The sodium isopropyl xanthate dosage ranges usually from 15 to 150 g/t of ore. Before flotation, sodium isopropyl xanthate is typically added to the pulp as a 3–10% by weight aqueous solution. Solutions should only be kept for a maximum of three days to prevent the production of carbon disulfide.

Although this substance has a wide range of industrial applications, mining industries most frequently employ it as a flotation reagent, like other flotation chemicals. Sodium isopropyl xanthate is employed in alkaline flotation circuits as a floatation collector for sulphide minerals. The product will decompose if used in acidic courses.

It is helpful to know that SIPX is regarded as a dangerous product because the substance is poisonous. Health effects from exposure to this substance may be short-term or long-term. The MSDS for Sodium Isopropyl Xanthate states that it has the potential to induce acute oral poisoning. If consumed or comes into contact with skin, it is exceedingly dangerous. It may seriously irritate your skin and eyes. So, SIPX suppliers recommend that this product be stored and disposed properly to prevent any adverse effects.


Different Grades Of Sodium Isopropyl Xanthate (SIPX)

To get to know various Sodium Isopropyl Xanthate (SIPX) forms and qualities, we should learn about this chemical’s production process; distinct production processes conducted to particular grades, varied by their properties, leading to different Mineral Processing Chemicals prices.

Alcohol, alkali, and carbon disulfide are treated to create xanthate salts. The action is known as xanthation. The nucleophile that adds to the electrophilic carbon center in CS2 is called an alkoxide due to the alkali and alcohol reacting to form one. The alkoxide is frequently produced by treating the alcohol with sodium or potassium hydroxide. For instance, sodium ethoxide makes sodium ethyl xanthate. This reaction can involve a wide variety of liquors.

Technical grades of xanthate salts typically have a purity of 90–95 per cent. Impurities can be residual raw materials such as alcohol and alkali hydroxide as well as alkali-metal sulfides, sulfates, trithiocarbonates, thiosulfates, or carbonates. As an example, sodium Isopropyl Xanthate with a pellet form might contain the substances below:

  • 90% of sodium isopropyl xanthate;
  • 0.2% of Free alkali;
  • 4% of Moisture and volatile.

Purity, which is expressed as a minimum percentage up to 100%, and moisture are the two xanthate composition classes each producer presents. Sodium isopropyl xanthate can be purchased as powder, granules, flakes, sticks, and solutions; each form is provided for a particular usage, holding a certain per cent of purity, which makes a specific grade. For instance, Floatation Frother Manufacturers provide SIPX for unique utility in froth flotation. But every ore is different, so there is no set flotation process, xanthate grade, or type employed to extract particular values. Still, some floatation frother suppliers provide unique qualities of Sodium isopropyl xanthate (SIPX) that are utterly reliable for mineral processing. To provide an example, SIPX 2309-T is a great Collector & Promoter that has been approved by many mineral processing plans worldwide for use in Copper and Gold flotation; JAM Group Co, as a Leading Floatation Collector Manufacturer, deliver this grade for every interested company.

SIPX 2309-T

SIPX holds various functions in many industries, but it is most commonly used in the flotation process of minerals. In this case, and for the best results, we need to employ high-purity chemical reagents to separate and concentrate ores. SIPX 2309-T possesses a standardized chemical composition that can be used as a great Collector & Promoter in the floatation process of copper and Gold. This quality of sodium isopropyl xanthate is provided by the JAM Group, a reliable floatation frother manufacturer that operates advanced technology to manufacture SIPX 2309-T from sulphur-based chemicals.

Moreover, compared to other collectors, SIPX 2309-T is environmentally friendly. It is also compatible with a vast range of pH, between 6 and 13.


Sodium Isopropyl Xanthate Production Process

Alkyl xanthates are among the most commonly used Asian, European, and Iran Mineral Processing Chemicals in the froth flotation beneficiation of base metal sulfide and precious metal ores. One example is sodium isobutyl xanthate. However, there are drawbacks to the commercial production of sodium isobutyl xanthate, including low productivity, poor containment, low yield, and environmental damage. An efficient procedure for synthesising xanthates using carbon disulfide as both a reactant and a solvent should be created to alleviate these problems. The solution presented in this article entails optimizing several process parameters. It considers the amount of solvent used, the temperature, the size of the caustic alkali particles, and the rate of agitation to speed up the conversion of sodium isobutyl xanthate (SIBX) and clarify the reaction kinetics.

Our intended method indicates that, compared to solvents like dichloromethane, petroleum ether, acetone, and water, carbon disulfide delivers products with a higher yield and higher purity. Furthermore, using commercial grainy/sheet caustic soda as the raw material without further pulverization enables the manufacture of high-purity xanthates with the addition of solvent. As a result, Mineral Processing Chemicals Manufacturers can employ this production process to create a high-purity grade of Sodium Isopropyl Xanthate (SIPX) suited for froth flotation and other standard functions.

Traditional Ways Of Producing SIPX

The environmentally friendly and economically viable manufacture of flotation collectors has received significant attention. However, in the traditional xanthate production business, low yield, operator injury, and environmental pollution are well-known problems. For instance, powdered caustic soda is necessary to speed up the reaction rate when producing xanthate using the conventional kneader method. The pulverization of grainy/sheet sodium hydroxide (or potassium hydroxide) makes a significant amount of highly alkaline dust hazardous to the environment and employees due to its high corrosivity and hygroscopicity.

Notably, these drawbacks include most traditional ways of producing SIPX; for example, creating Europe, Russia, and China Mineral Processing Chemicals may result in these problems. When xanthates are manufactured in these countries using the kneader approach, many impurities are created through unintended side effects. These impurities not only lower the yield but also have a negative impact on the stability of the xanthates. In addition, the resultant product has a disagreeable scent due to the presence of contaminants. Additionally, the kneader method results in the volatilization of 20 kg on average of organic chemicals, such as carbon disulfide, while manufacturing one ton of xanthates.

The Suggested Way Of Producing SIPX

In the previous section, we mentioned why traditional ways of producing SIPX, like the method manufacturers in Russia for Mineral Processing Chemicals employ, require revision and reconsideration.

Solvents are frequently used in organic transformations because they are crucial in homogenizing the reaction and boosting the effectiveness of molecular interactions. Solvent increases the mass and heat transmission, improves selectivity, and makes it simple to regulate reaction pace and achieve industrial applications. Therefore, both in the laboratory and in the chemical industry, the selection of the proper solvent is of utmost practical significance. This procedure differs from the traditional solvent approach in that it makes Floatation Collector suppliers and Manufacturers employ carbon disulfide as the reactant and solvent instead of dichloromethane, toluene, acetone, or petroleum ether. The main reason is that carbon disulfide can be recovered and reused more easily than alcohol without contaminating the water.

Excess carbon disulfide can be used to make xanthates without the need for the caustic alkali to be ground up. It can efficiently regulate heat transmission by maintaining the reaction in the liquid phase. Due to the mild nature of the reaction, chilled brines can be replaced with cold water as the coolant. The lack of local overheating significantly reduces the development of by-products, resulting in a higher yield and improved purity with the mild process. It has been claimed that manufacturing sodium isobutyl xanthate (SIBX) utilizing excess carbon disulfide results in a purity of 90 to 97%, respectively. It happens while using a kneading machine in china, Russia or Turkey for Mineral Processing Chemicals production, Resulting in a SIPX with 84 to 91% purity.
