Portland Cement Kiln Dust Reprocessing
From 10 to 12 million tons of cement kiln dust accumulate annually at domestic cement plants. This finely divided dust is emitted from cement kilns to prevent the buildup of excessive salts in the cement product. The alkali salts in the dust are derived from the clay raw materials, which include potassium and sodium feldspars. […]
Flocculation & Zeta Potential Measurements
Chemicals: Reagent grade H2SO4 and KOH were used for pH adjustment. Aluminum sulfate was used for coagulation and zeta potential studies. Percol 368 a solid grade highly cation flocculant by Allied Colloids Inc. was used for flocculation and zeta potential measurements.

Remove Selenium from Water
Selenium (Se) is encountered in surface and groundwaters in the United States at concentrations that rarely exceed the drinking water standards (0.01 mg/L). However, in the western United States, leachates from heap-leaching operations at gold mines may contain selenium concentrations as high as 2 mg/L. In the gold heap leaching process, a solution containing sodium […]
Recovering Cadmium & Tellurium from Scrap
Two materials critical to the construction of several advanced photoelectric devices are cadmium and tellurium. CdTe is used in thin-film photovoltaic (PV) devices to absorb electromagnetic radiation (visible sunlight) and convert the energy into an electric current. The Solar Energy Research Institute (SERI) estimates that demand for CdTe in these PV devices could reach 260 […]
