Abstract
Se investigó la influencia de la dosis del aeropromotor AZ-4 y el porcentaje de granulometría en
la recuperación de óxido de plomo (cerusita y anglesita), mediante flotación selectiva de un mineral
mixto con sulfuros y óxidos de plomo, los análisis de difracción de rayos X, muestran las
composiciones químicas de los diferentes elementos tales como Cerusita 2%, anglesita 4%, galena
5%.
Para la flotación de óxido de plomo, se utilizó un diseño bifactorial con tres niveles, el primer
factor dosis del aeropromotor AZ-4 con sus respetivos niveles de 345 g/t, 690 g/t, 1150g/t, el segundo
factor porcentaje de granulometría con sus respectivos niveles 50%,55%,60%, siendo la variable
dependiente la recuperación de óxido de plomo.
Los resultados muestran que la máxima recuperación de óxido de plomo es 55% y se obtiene con
dosis del aeropromotor AZ-4 de 1150 (g/t) y un porcentaje de granulometría del 60%.
Las variables aeropromotor AZ-4 y granulometría (% - #200), según los resultados del análisis
de varianza, con un nivel de significancia del 95%, indican que la dosis de AZ-4 (P value = 0.342)
así como el porcentaje de granulometría (P value = 0.876) y la interacción de ambas variables
(p value =1) no tienen una influencia significativa en la recuperación de óxido de plomo.
The influence of the dose of the AZ-4 aeropromoter and the percentage of granulometry on the recovery of lead oxides (cerussite and anglesite) was investigated, through selective flotation of a mixed mineral with sulfides and lead oxides, ray diffraction analysis. X, show the chemical compositions of the different elements such as Cerussite 2%, anglesite 4%, galena 5%. For the flotation of lead oxides, a two-factor design with three levels was used, the first dose factor of the AZ-4 aeropromoter with its respective levels of 345 g/t, 690 g/t, 1150g/t, the second factor percentage of granulometry with their respective levels 50%,55%,60%, the dependent variable being the recovery of lead oxide. The results show that the maximum recovery of lead oxide is 55% and is obtained with a dose of the AZ-4 aeropromoter of 1150 (g/t) and a granulometry percentage of 60%. The AZ-4 and granulometry aircromotor variables (%- #200), according to the results of the variance analysis, with a 95% level of significance, indicate that the AZ-4 dose (P value = 0.342) as well as the percentage of granulometry (p value = 0.876) and the interaction of both variables (p value = 1) do not have a significant influence on the recovery of lead oxide.
