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...
Nickel (Ni) deposits are depleting, while demand for the metal is increasing. To address this problem, valuable metals such as Ni and Fe can be extracted from secondary sources limonite-type laterite ores. The goal of study was to investigate influence leaching temperature on recovery, well best kinetic model represent process these metals. Temperature has a considerable impact Fe. Increasing 3...
Nickel (Ni) and associated minerals (Cr Mn) are naturally occurring substances in ultramafic laterites soil. It may be found our vegetables grains when agriculture is grown laterites. This study aimed to assess the contamination of Ni edible crops affected by soil volume mono- mixed cropping on limonitic laterite The investigation was conducted Peanut (Arachis hypogaea L.) Choy Sum (Brassica ra...

Myanmar has a drier sub-tropical climate than countries that typically contain Ni laterite deposits, but hosts deposit at Tagaung Taung. Given enrichment processes in the Taung are poorly understood, we investigated geochemical and mineralogical evolution of two weathering profiles developed on different bedrocks central part Myanmar: partly serpentinized harzburgite an almost completely perido...
