In this Study, vanadium recovery from the steelmaking converter slag was studied. Salt roasting-basic leaching is the process which was applied to separate and extract vanadium from steel making slag. Ground slag was roasted after mixing with determined quantities of sodium carbonate. The effect of time and temperature of roasting and sodium carbonate content were studied. The optimum temperatu...

Vanadium is distributed widely and scarcely (150 ppm) on the earth. Its major applications are in steelmaking, dye-production and catalyst-fabrication industries. With the ever-increasing demand for this metal, secondary resource-exploitation of such waste materials as spent catalysts is recommended. Many reactions are involved in vanadium-extraction from these resources. Since roasting in comp...

The effects of particle size, fermentation, roasting time and roasting temperature of cocoa nibs on cocoa butter extraction using supercritical fluid technology were studied. The effect of particle size was studied using cocoa liquor (D = 0.074 mm), ground cocoa nib (D = 0.25–0.50 mm and 1.0–1.2 mm) and whole cocoa nibs at 35 MPa, 60 C and flow rate of 2 ml/min using supercritical carbon dioxid...

in this research roasted and sonicated rice bran were added at different levels (0, 5, 10, and 15% w/w) to wheat flour for the production of semi-voluminous bread. dough's rheological properties as well as textural and sensory characteristics of bread were investigated. the results showed that water absorption (%), development time (min) and the degree of dough softening (fu) were increased but...

Proximate, mineral and amino acid compositions of raw and processed red kidney bean (Phaseolus vulgaris L.) flour were investigated on dry weight bases with a view to finding alternative and cheaper sources of protein to solve the problem of malnutrition due to inadequate protein in nutrition which is a prevalent problem in developing world, especially in Nigeria. Processing methods (cooking, b...

OBJECTIVE This study observed the effects of cooking method and final core temperature on cooking loss, lipid oxidation, aroma volatiles, nucleotide-related compounds and aroma volatiles of Hanwoo brisket (deep pectoralis). METHODS Deep pectoralis muscles (8.65% of crude fat) were obtained from three Hanwoo steer carcasses with 1+ quality grade. Samples were either oven-roasted at 180°C (dry ...
