What is the formula of potassium ethyl xanthate?

C3H5OS2KPotassium ethyl xanthate / Formula

What is the use of potassium ethyl xanthate in froth floatation?

The function of potassium ethyl xanthate in froth floatation process is to make the ore Water repellant. The metallic ore particles are preferentially wetted by the oil and rise to the surface along with the froth.

What is xanthate used for?

Xanthates are a group of chemicals typically used in sulphide flotation in mining applications.

What is Pax chemical?

Potassium Amyl Xanthate is also known as PAX and its chemical formula is CH3(CH2)4OCS2K. It is a water soluble, pale yellow powder. Potassium Amyl Xanthate (PAX) is cataloged as a reactive flammable material. This product has the potential to create combustible dust clouds in the air.

Which of the following is a method of concentration of ore?

Ore concentration can be accomplished through a variety of methods, including hydraulic washing, magnetic separation, froth flotation, and leaching.

Is potassium amyl xanthate corrosive?

In the presence of moisture (perspiration, humidity, tears), the dust dissolves to form a corrosive solution which may cause burns. (3) Potassium Amyl Xanthate may cause symptoms of skin irritation such as reddening, swelling, rash, scaling, or blistering. May cause defatting, drying and cracking of the skin.

What does xanthate mean?

Definition of xanthate : a salt or ester of any of various thio acids and especially C3H6OS2.

What is potassium amyl xanthate used for?

Potassium amyl xanthate (/pəˈtæsiəm ˌæmɪl ˈzænθeɪt/) is an organosulfur compound with the chemical formula CH3(CH2)4OCS2K. It is a pale yellow powder with a pungent odor that is soluble in water. It is widely used in the mining industry for the separation of ores using the flotation process.

What is roasting and calcination?

Calcination is a process in which ore is heated in the absence of air or air might be supplied in limited quantity. Roasting involves heating of ore lower than its melting point in the presence of air or oxygen. Calcination involves thermal decomposition of carbonate ores.

Which ores is best concentrated by gravity separation?

The gravity separation process uses this property for the concentration of ore. -Hematite ore is concentrated using the gravity separation process. Hematite is a common ore of iron oxide.

What happens when potassium amyl xanthate Burns?

How do you make xanthate?

Cellulose xanthate is prepared by first immersing cellulose pulp in aqueous sodium hydroxide to convert to alkali cellulose. The alkali cellulose is then depolymerized to control the alkali cellulose degree of polymerization prior to xanthation in carbon disulfide.
