Effect of Physicomechanical Factors on Textural Characteristics of Silica-Rich Phosphorite

详细

The effect of physicomechanical factors (drying temperature and compaction pressure) on the specific surface area and total pore volume of size fractions of preground phosphorite from the Polpinskoe deposit has been studied using low-temperature nitrogen adsorption measurements. The results demonstrate that the textural characteristics of the phosphorite are determined by the constituent alpha-quartz, are essentially independent of the degree of comminution of the raw material, and are insensitive to the effect of temperature and pressure under the conditions studied.
