Potassium Amyl Xanthate, What is Potassium Amyl Xanthate ...

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.

Froth Treatment Explained | Oil Sands Magazine

Froth Treatment is a process by which water and fine solids are removed from bitumen froth using hydrocarbon-based gravity separation. There are two different types of hydrocarbons used in Froth Treatment: a naphtha-based hydrocarbon and a lighter paraffinic solvent. Both produce a relatively clean bitumen product but only a paraffinic process produces a marketable product stream.

Pine oil - Wikipedia

Froth flotation. Industrially, pine oil is used as a frother in mineral extraction from ores. For example, in copper extraction pine oil is used to condition copper sulfide ores for froth flotation. Therefore, it is important in the industry for the froth flotation process. It has largely been replaced by synthetic alcohols and polyglycol ethers

Tailings.info What are tailings? - Their nature and production

Concentration is the process of extracting the economic product from the crushed and ground ore, the waste from this process is the tailings. Froth flotation (figure 2) is the most widely used concentration method and is normally the first step in the mineral processing sequence where chemical reagents are introduced (Vick 1990).
