Copper is an important strategic resource for the national economy and social security of China. Water use a significant component copper production. However, water shortages pollution are two global crises in management. In this study, production industry China was studied from perspective footprint (WF) ecological (eco-industry). A WF inventory built by accounting entire supply chain process,...

Cadmium, Hg, Pb, and Zn concentrations were determined in 28 species of red, brown, and green algae sampled in the south-western coast of Sardinia (Italy). Elevated concentrations of heavy metals were mainly associated with the presence of smelting activities in the area.

Scuttle flies trapped at baits of dead mice are reported from a region of S. W. Finland subjected to pollution from the smelting of copper and nickel. Most belonged to the huge genus Megaselia, but 96% were females, the majority of which cannot be named until linked to their males. These are given code numbers and distinguished by means of a key.

Two men developed acute intravascular haemolysis after exposure to arsine gas in a metal smelting works. Both survived; one developed acute renal failure and required peritoneal dialysis. His renal function returned to near normal within 3 months. The probable mode of exposure has been investigated and is discussed. The toxic effects of arsine are briefly reviewed. The preventive action taken i...

Titanium slags produced through ilmenite electric furnace smelting contain 60–80%TiO2, a vital titanium resource in the industry. The processing and utilization of slag is faced with many challenges, such as complex mineral structures, high requirements, severe environmental pollution, heavy additives energy consumption. This study aims to review technologies for slag. First, we analyze charact...

Field experiments in copper smelting were carried out order to test assumptions about the production processes employed at Vilabouly Complex (VC), an Iron Age extraction and site central Laos. VC is one of only three primary sites known Southeast Asia appears be a major mining locale. Analytical results on assemblage (ores, crucibles, slag fragments alloy objects), along with geological informa...

Copper slag (CS) is an abrasive blasting grit made of granulated slag from metal smelting processes. As copper slags are known to be waste material and cause a lot of environmental problems, it would be a good idea to use them in different sections of industry such as pavement construction. On the other hand, in order to save energy and reduce the amount of pollutants re...
