Study on Moisture Adsorption Equilibrium Model of Lead Concentrate
Abstract: In order to build a more applicative moisture adsorption equilibrium model of lead concentrate, the partial correlation analysis of different factors to moisture adsorption content is conducted basing on the previous experimental works. It shows that the temperature and relative humidity, the correlations are −0.927 and 0.932 respectively, are decisive factors. And then, based on the original Langmuir equilibrium adsorption model, two modified Langmuir models are built by theoretical and empirical methods, which are controlled by the temperature and relative humidity. The analysis and comparison of two models shows that the empirical modified Langmuir equilibrium model is more applicative to the lead concentrates under the 20˚C - 80˚C of temperature and 45% - 95% of RH. So, the empirical modified Langmuir equilibrium model can be employed to calculate the moisture adsorption content of lead concentrates in the industry to some extent.
