Lead paste desulfurization is a process used by new lead processing plants to reduce the sulfur dioxide emissions and waste sludge. The air emissions in older plants are usually controlled with settling and cooling chambers and with baghouse emissions control equipment.
The present paper reviews the situation and technology progress of lead smelting in China. According to the new lead smelting processes, this paper also presents a lead .
Quantification of the total concentration of solid particles of lead smelting dust TSP in mg/m 3 was performed gravimetrically, applying the method given by Rabah . External emissions that may contribute to the measurement of TSP (such as vehicles or other plants) were separately measured and considered.
Examples include nickel carbonyl in nickel refining, fluorides in aluminium smelting, arsenic in copper and lead smelting and refining, and mercury and cyanide exposures during . These processes require their own special precautions.
