Product Basic Information and Parameters

Ammonium polysulfide, with the CAS number 12259-92-6, is a chemical compound known for its high - quality and is offered at the best price in the market. The chemical formula of ammonium polysulfide is (NH₄)₂Sₓ, where x represents the number of sulfur atoms in the polysulfide chain, usually ranging from 2 to 6.

It is typically a yellow - to - orange liquid with a characteristic unpleasant odor similar to that of hydrogen sulfide. The density of ammonium polysulfide varies depending on the concentration and sulfur content but is generally around 1.1 - 1.3 g/cm³. It is soluble in water, and the solubility can be affected by factors such as temperature and pH.

Product Applications

One of the main applications of ammonium polysulfide is in the mining industry. It is used as a flotation reagent for the separation of metal sulfide ores. For example, in the flotation of copper, lead, and zinc sulfide ores, ammonium polysulfide can improve the hydrophobicity of the target minerals, making them easier to separate from gangue minerals.

In the field of analytical chemistry, it can be used as a reducing agent and a complexing agent. It can react with certain metal ions to form stable complexes, which is useful for the qualitative and quantitative analysis of metals. Additionally, it is used in the production of dyes and pigments. It can participate in chemical reactions to form colorful compounds, which are widely used in the textile, paint, and printing industries.

Product Usage

When using ammonium polysulfide, proper safety precautions must be taken. It should be stored in a cool, dry, and well - ventilated place, away from heat sources and oxidizing agents. Before use, it is necessary to wear appropriate personal protective equipment, such as gloves, goggles, and a respirator.

In the mining industry, the appropriate amount of ammonium polysulfide is added to the flotation pulp according to the ore characteristics and process requirements. The addition rate and concentration need to be carefully controlled to achieve the best flotation effect. In analytical chemistry, it is usually added in solution form, and the reaction conditions such as temperature, pH, and reaction time should be strictly controlled.

Product Use Cases

Case 1: A copper mine in South America was facing challenges in the flotation process of its copper sulfide ore. The original flotation reagents were not effective in separating the copper sulfide from the gangue minerals. After switching to ammonium polysulfide, the recovery rate of copper increased from 80% to 90%. The company adjusted the addition rate of ammonium polysulfide to 500 g/t of ore, and the pH of the flotation pulp was maintained at around 7 - 8. As a result, the quality of the copper concentrate was significantly improved, and the production cost was reduced due to the lower reagent consumption.

Case 2: A chemical analysis laboratory needed to determine the content of a certain metal ion in a sample. They used ammonium polysulfide as a complexing agent. By adding an appropriate amount of ammonium polysulfide solution to the sample under specific pH and temperature conditions, a stable complex was formed. This complex could be easily detected and quantified by spectroscopic methods, which greatly improved the accuracy and efficiency of the analysis.
