Extractive Metallurgy of Copper | ScienceDirect
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 ...

Chemical modification of vegetable oils for the production
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.

The useful life of electrical and electronic equipment (EEE) has been shortened as a consequence of the advancement in technology and change in consumer patterns. This has resulted in the generation of large quantities of electronic waste (e-waste) that needs to be managed. The handling of e-waste including combustion in incinerators, disposing in landfill or exporting overseas is no longer ...

The majority of published material regarding the operation of crushing machinery is concerned with simulation of performance rather than design of equipment. The reason underlying the bias in published material relates to why research is carried out and who undertakes the research. Two distinct types of research can be identified: 1. Internal research by crusher...

A study of storage tank accidents - ScienceDirect
A 1970 crack at the bottom of a crude oil storage tank at a Kaohsiung, Taiwan refinery was attributed to the slow subsidence of the foundation . Both crude oil spills from storage tanks into bunds at a Kaohsiung, Taiwan refinery in 2002 and at a Fawley, Hampshire, UK refinery were caused by the corrosion of tank bottom (UKHSE, 2000).
He concluded that: "Pressure, gravity and molecular cohesion can all be driving forces in the operation of siphons". In 2014, Hughes and Gurung (at the Queensland University of Technology), ran a water siphon under varying air pressures ranging from sea level to 11.9 km (39 000 ft) altitude.
