The influence of certain flotation factors in the beneficiation of tungsten ores

Abstract

The success of mineral processing by flotation depends on very many factors. However, the literature has not yet paid due attention to this issue. The optimal values of all factors that mutually influence one another for each object of study are established experimentally, which, given the large number of factors, makes it extremely difficult to establish the optimal flotation regime. Below we briefly present the results of a study of the influence of some flotation factors on the enrichment of hübnerite ore, which are usually not attributed much importance (see the article). From the above materials it should be concluded that during the flotation of hübnerite ore in the presence of oleic acid and sodium oleate, a sharp improvement in flotation results is observed with fractional loading of the collector (7-8 portions, with a total consumption of 0.5-0.7 kg/t), adding potassium bichromate as a deflocculator, with a high pulp density (33-50% solid). Establishing the optimal values of the listed factors made it possible to sharply increase the degree of concentration during primary flotation, and this circumstance, in turn, provided the possibility of effective cleaning operations.
