Based on the determination of major and trace element content, Sr isotope composition soils from limestone dolomite profiles in karst area Southwest (SW) China, this study discussed distribution migration characteristics elements influencing factors fractionation, order to better understand chemical weathering pedogenesis process, as well explore material source laterite. The analysis results (...

Laterite steel is that has a nickel content of up to 2%. The can produce with superior properties such as: high strength, corrosion resistance, and good weldability properties. With the nature laterite needed in main tool indonesian national tantara weapon system. To find out performance damage bulletproof materials, then conducted research on this as tough armour material by conducting form me...

In arid areas, the rapid evaporation of water leads to severe shortage for plant growth. Superabsorbent polymers have prospect preventing because its excellent absorbency. However, insufficient in salt resistance, retention, and swelling rate limit application. Herein, we fabricated Hydroxyethyl cellulose-g-(Acrylic acid-co-2-Acrylamido-2-methyl-1-propane sulfonic acid)/laterite (HEC-g-P (AA-co...

Ferronickel products obtained from the traditional process used to treat limonite nickel laterite usually assay very low-grade Ni, only 3–5% Ni due high Fe/Ni ratio of laterite. This paper describes an investigation conducted upgrade laterites for preparation ferronickel by using selective reduction smelting technology. By means thermodynamic calculations and experiments, separation mechanism b...

Laterite soil is an embankment that often used because it easy to find and widely found in South Kalimantan. However, this land has many shortcomings be as soil. This the lateritic a clay content high Plasticity Index (PI) value. So quality still questionable landfill. To overcome this, necessary improve or stabilize In study, was stabilized by addition of slag nickel study aims determine physi...

Cultural factors affecting the production of L-asparaginase by Streptomyces tendae isolated from laterite soil samples of Guntur region were investigated on glycerol-asparagine-salts (modified ISP-5) broth. Optimal yields of L-asparaginase were recorded in the culture medium with the initial pH 7.0 incubated at 30 degrees C for 72 h. The strain utilized sucrose (2%) and yeast (2%) extract as ca...
