Recycle of Wastewater from Lead-Zinc Sulfide Ore Flo-tation Process by Ozone/BAC Technology
Lead-zinc sulphide ore Ozone/BAC flotation wastewater recycle
2013/3/9
Lead-zinc sulphide ore contains lead sulphide (galena), and zinc sulphide (sphalerite). In the first flotation stage, galena is rendered hydrophobic with an organic collector such as xanthate, while s...
Comparing the Adequacy of Some Non-Homogeneous Poisson Models to Estimate Ozone Exceedances in Mexico City
MCMC Algorithms Non-Homogeneous Poisson Models Change-Points Ozone Air Pollution Mexico City
2013/3/11
We consider some non-homogeneous Poisson models to estimate the mean number of times that a given environmental threshold of interest is surpassed by a given pollutant. Seven different rate functions ...
Using Spatial Econometrics to Measure Ozone Pollution Externalities
Air Pollution Externalities Spatial Econometrics
2013/3/11
This paper summarizes my previous work in Lin (2010), in which I use spatial econometrics to analyze air pollution externalities. In Lin (2010), state-by-state source-receptor transfer coefficients th...
