of washed bauxite ore,bauxide residue(1.54 tonnes)to produce 1 tonne of alumina,and gaseous emissions(SO2 emission of 1.15x10 kg and Total Flouride of2.33x10-4 kg)during primary aluminium production.While for CO2 emissions accounted for 1.29x10 tonnes per 1 tonne of aluminium ingot production ...
As the colours indicate, the life cycle of a casting product can be divided into six phases: metal extraction (yellow - also known as primary aluminium production), extraction of sand and its additives (green), casting (red - Casting can be treated as secondary aluminium production), mould ...
摘要: The process for anodizing a workpiece of aluminum or aluminum alloys provides for the use of the workpiece as the anode of an electrolytic cell in the presence of an aqueous acid solution which contains from 10 to 200 g sulfuric acid and from 5 to 200 g L(+)-tartaric acid....
In every step of our production process and value chain, from raw material sourcing and movement of wastes and end by-products, Qatalum always seek to avoid, if not, as much possible minimize its impact on the environment. The Qatalum Production System has core principles of eliminating waste...

The further studies has found that the real components behind the phenomenon being responsible to the impact are some AMCs from fabs' environment, such as F, Cl, S, NH3, VOC, and etc. This Studies lists several key and very harmful AMCs which impact IC CP yield and line yield most, ...
However, the environmental impact of process adaptations also must be considered, which is generally positive in the case of using less energy but could be negative in the case of cheap e ... 展开 DOI: 10.1007/s11837-015-1395-7 年份: 2015 ...
