Experimental Study on the Selectability of Tailings from a Super Poor Vanadium Titanium Magnetite Mine in Xinjiang
To conduct a practical analysis on the washability of a certain ultra-poor vanadium titanium magnetite tailings.Firstly,this paper analyzes the grade of the selected magnetite tailings,clarifies the corresponding grade range,and based on this,determines the initial recyclability.Subsequently,a combination of flotation columns and vibrating screens was used to perform correlation measurements on the tailings.For magnetite tailings with multiple particle sizes,the final optional recovery rate was determined at different testing temperatures to obtain the resulting data.There are significant differences in the optional recovery rates of ultra-poor vanadium titanium magnetite tailings with different particle sizes at different testing temperatures.The smaller the particle size of the tailings,the higher the temperature,and the corresponding optional recovery rate is higher.On the contrary,the larger the particle size of the tailings and the lower the temperature,the lower the corresponding optional recovery rate.Under the background conditions of flotation testing,tailings with different particle sizes are optional for recovery.The higher the temperature,the higher the recovery rate of tailings with smaller particle sizes,and the stronger the washability.The lower the temperature,the lower the recovery rate of tailings with larger particle sizes,and the poorer their washability.The degree of selectivity of tailings is positively correlated with temperature and particle size.During the testing process,the more components exist in the tailings,the less difficult it is to recycle and select.
