Classification of Tungsten Ore Flotation Reagents
From dressing industrial progress of history suggests that mineral processing reagents application significance is self-evident. Since its discovery in 1924 xanthate has the function of collecting sulfide ore, the development of the flotation industry started by leaps and bounds, the inundated mineral processing reagents has been invented and created with a steady stream.
However, how many dressing agent are they? How to classification, which is often confused about.
In western countries, most of dressing agent were issued in the form of “patent certificate”.
Therefore some names are quite chaotic, sometimes it only some numbers. At the same time, the dressing agent is more cheaper in general, other impure industrial by-product, its composition is not very sure; And several kinds of medicine emulsion mixture or the product of interactions, often name after the new potion. According to a German experts statistics, there are 7702 species the name of the material can be used as a flotation reagents. Of course, many of which are of the same compound has several names, or the same agents has several patents registered brand, according to rough estimates, about two or three thousand kinds of flotation reagents.
In the face of two or three thousand kinds of flotation reagents, how to classify them with well-regulated, there are different opinions. Currently internationally recognized common flotation classification method is classified by pharmaceutical function, can be divided into: collecting agent, foaming agent, activator, inhibitors, pH adjusting agent, flocculant six types, classification of tungsten ore flotation reagents are also the same. Usually we use tungsten collector with fatty acid, sulfonic acid, phosphoric acid, chelation, amine, oil; Activator mainly lead nitrate; Inhibitors have organic and inorganic inhibitors inhibitors; PH adjustment mainly sodium hydroxide and sodium carbonate, in addition, most of tungsten ore flotation collector has a sparkling performance, so the tungsten flotation use fewer special foaming agent.
