Abstract Local clay mineral was mined from Okpella Town, Etsako Government Area of Edo State, Nigeria. Mineralogical characterization the carried out using X-ray diffraction analyzer. Chemical fluorescence analyzer and pH analysis meter. The mineralogical revealed that majorly a dolomite having 72% dolomite. impurities present are 18% cristobalite, 4.1% garnet, 5% calcite 1% quicklime. acidic a...

The thrust of this research study was to ascertain the physicochemical characteristic in settling particulate matter and sediments samples collected from wellington industrial estate flood plains; main objectives are as follows: determine hydrogen ion index (pH) area, electrical conductivity (EC) same location. Samples were six locations (at varying depths 0 - 5 cm 10 cm) sample area 1 (Welling...
