Three kinds of samples (,acid, mine drainage, coal mine ,wastewater,, and thermal spring) derived from different sites were collected in China. Thereafter, these samples were combined and then inoculated into a basal salts solution in which different substrates (ferrous sulfate, elemental sulfur, and chalcopyrite) served as energy sources.

The procedure is a manual method of determining the concentration of total mercury using an ,acid, aqueous solution of potassium permanganate or potassium ,dichromate, for the sampling of vapour-phase mercury, together with a filter paper for the collection of particle-bound mercury. The sampling time should be between 30 minutes and two hours.

More- over, the NOx/SO2 change is followed within 5-15 minutes by a CO spike, the kiln's indicator of a momentary process instability. As shown in Figure 2, this event was recurring. ,ACID, GASES Cement kilns are, by their alkaline nature, built-in control devices for ,acid, gases such as SO2 and HC1.

A series of geochemical reactions between the sulfuric ,acid, derived from the oxidation of pyrite in the presence of O2 and H2O, diluted in groundwater, and the calcareous carbonate minerals of the wall rock and the neighboring lithological formations (limestone and flysch) have led to the neutralization of the acidity and the formation of secondary sulfate minerals such as gypsum and ,jarosite,.
