Due to the decreasing production of nickel and cobalt from sulfide sources, the Ni and Co extraction from the oxide ores (laterites) have become more prevalent. In this research work, the effects of calcination prior to leaching, acid concentration, percent solid, pH, and stirring speed on the nickel and cobalt recoveries from an iron-rich laterite ore sample were investigated using diffe...

The study is about measuring the unsaturated fatty acids, as well as, Omega acids by using GC/Mass in addition to HPLC extract and measure of some Iraqi local nurtures. Concentrated extracts linseed oil, sunflower butter, black seed, and, extracted oil Carp fish were measured. results are shown tables 6 7.Calcium, Potassium, Iron, Zinc, Magnesium rates into oils measured Atomic Absorption appar...

Molecular recognition emerges from non-covalent interactions and is of paramount importance for understanding of biological processes, ranging from enzymatic activity to DNA base pairing, as well as in the design of functional supramolecular systems, for example, molecular motors, sensors, ion receptors, or systems used in waste management. In the specific area of selective anion binding, numer...
