Lead and Zinc Lead and zinc ores are usually found together with gold and silver. A leadzinc ore may also contain lead sulfide, zinc sulfide, iron sulfide, iron carbonate, and quartz. When zinc and lead sulfides are present in profitable amounts they are regarded as .
coal through washing and beneficiation can reduce its ash and sulfur content, provided that care is taken in handling the large quantities of solid and liquid wastes that are generated by the cleaning process. An alternative to coal cleaning is the cofiring of coal with higher and lower ash content. In addition to reduced particulate emissions,
It can be seen that washability is changing from coarse size to fine size. Washability curve related to fine size for both of Hırsızpınarı and Tekçam regions has a negative effect due to their decreasing porosity in fine particle size.

Apart from concerns about safety and combustion, the operating costs can be high if very high gas or air temperatures are used. The aim of this study was to investigate the removal of moisture from fine coal by using air at a lower temperature (25°C − 40°C) within a controlled environment by lowering the relative humidity of air.

Moisture in coal varies from the point where it is received to the point where it enters the boiler. The variation in the moisture affects the reported heating value and analysis. The laboratory analysis is required to be corrected to the actual moisture content in the field. Methods for applying these corrections are explained here.

Postcombustion CO 2 capture technologies remove CO 2 from the combustion flue gas of a power plant following combustion of a fossil fuel. It is primarily applicable to conventional coal, oil, or gasfired power plants. In a typical coalfired power plant, fuel is burned with air in a boiler to produce steam that drives a turbine/generator to produce electricity.
