    This chapter reviews the solvent extraction transfer method of copper from leach solution to electrolyte. Solvent extraction transfers dissolved copper (Cu) from low Cu ++, impure pregnant leach solutions to high-Cu ++, pure electrowinning electrolytes. It is a crucial step in producing high purity electrowon copper from leached ores.

    Gas-wetting alteration is a versatile and effective approach for alleviating liquid-blockage that occurs when the wellbore pressure of a gas-condensate reservoir drops below the dew point. Fluorochemicals are of growing interest in gas-wetting alteration because of their high density of fluorine groups and thermal stability, which can change the reservoir wettability into more favorable ...

    5.1. Viscosity. Viscosity is a measure of biolubricant’s thickness, or resistance to flow. Quantitative measure of fatty acids’ and vegetable oils’ resistance to flow is called viscosity , .The higher the biolubricant’s viscosity, the thicker it will be and more energy will be needed to move an object through it , .Viscosity is a major factor which determines biolubricant’s application.
