A STATISTICAL INVESTIGATION OF FACTORS INFLUENCING FLOTATION OF WOLFRAMITE

An attempt was made to apply the method of statistical analysis to research in the flotation of wolframite.The statistically designed experiment studied the effects of six factors,i.e.,(A)grainsize,(B)mode of the generation of airbubbles,(C)pH value of the pulp,(D)acid treat-ment,(E)quantity of the frother used,and(F)temperature of the pulp.The analysis of variance showed that,in the case of wolframite flotation whensodium oleate was used as a collector,the grain size,pH value and temperature of thepulp are the significant variables.The analysis of the interactions between the variables led to best synthetic techno-logical conditions.
