The energy consumption of Korea’s manufacturing sector has sharply increased over the past 20 years. This paper decomposes the factors influencing energy consumption in this sector using the logarithmic mean Divisia index (LMDI) method and analyzes the specific characteristics of energy consumption from 1991 to 2011. The analysis reveals that the activity effect played a major role in increasin...

Metal/carbon composite plating is an effective strategy for improving and adding properties to metal by incorporating carbon materials into the matrices. Copper (Cu) widely applied, particularly in areas of heat management electronic packaging owing its high thermal electrical conductivities, which can be further improved together with improvements mechanical compositing it nanotubes (CNTs). Ho...

Abstract Wastewater containing cobalt and copper comprised of plating wash water, plant equipment cooling water is generated in the electroplating industry. These metals can be detrimental to humans, animals, plants, environment. Thus, it necessary treat wastewater remove these toxic metals. Carbonate hydroxide precipitation were utilized for removal Co (II) Cu from synthetic by jar tests this ...

The trend in the industry T H E MINERAL-PROCESSING INDUSTRY is , and will remain, very sensitive to the metal market, which in turn is very dependent on the use of metals for the improvement of lifestyle in developing and developed countries. An assumption is made that the weapons industry will have a reduced effect in the future on the use of metals, and therefore on prices. The cost of metal ...
