Four cost effective organoclays were synthesized, characterized, and studied for the sorption of hydrophobic compounds (edible oil/grease and hydrocarbon oil) from aqueous solutions. Organoclays were prepared by cation exchange reaction of lattice ions (present onto the surface of laterite and bentonite clay minerals) with two surfactants, hexadecyl trimethyl ammonium chloride (HDTMA-Cl) and te...

An erosional landscape characterized the Western Ghats in the Deccan Volcanic Province of India. The upland region shows the absence of sedimentological records for the stratigraphic period from post-Eocene to prePleistocene, except laterites which are extensively developed. The absence of any sedimentological records, therefore, has put severe constraint on the reconstruction of the Tertiary h...

According to the classification of the nickel laterite, this paper describes mineralogy test is to reveal where valuable elements are located in the ore, in which mineralogical form. The purpose of the sieving test was to study if some specific particle size contains most of the valuable metals. Based on its chemical composition nickel laterite is classified as a limonite type and the nickel an...

In this work, we characterised the thermophysical parameters of Thicky laterite as a function water content and also cement in mix. For with diameter less than or equal to 1.25 mm, thermal conductivity is 0.388 W/m.K for close 0%, increases 87.37% 3.46%. Laterite without has strength 2.309 MPa, by 4.80 %, 13.16 18.45 % 47.82 respectively when 4 6 8 10 added laterite. The flexural changes mix, f...

The incorporation of laterite in sandcrete blocks production is a common commercial practice Nigeria. However, proper calibrations as per optimal mix proportions these aggregates to give that meet minimum requirements by various standards are lacking. In this study, ratio 1:8 (cement: aggregates) and water-cement 0.5 was adopted at different percentages replacing sand. Block sizes 450 x 225 150...
