Aluminum smelting
Hans Christian Oersted first heated potassium amalgam with aluminum chloride and produced tiny pieces of aluminum in 1825. This was twenty years after Sir Humphrey Davy first named the metal “aluminum.” Davy was the first to use electrolysis to produce samples of potassium, sodium, strontium, calcium, barium, magnesium and boron. He tried unsuccessfully for many years to produce aluminum by ele...
متن کاملThe Aluminum Smelting Process
This introduction to the industrial primary aluminum production process presents a short description of the electrolytic reduction technology, the history of aluminum, and the importance of this metal and its production process to modern society. Aluminum's special qualities have enabled advances in technologies coupled with energy and cost savings. Aircraft capabilities have been greatly enhan...
متن کاملRecirculation of Chilean Copper Smelting Dust with High Arsenic Content to the Smelting Process
Most of the dust generated from the copper smelting process in Chili has been stored after the stabilization by hydrometallurgical process because it contains high concentration of arsenic. However, in recent years, the generation of dust has increased because of degrading the quality of concentrate. In addition, the environmental regulations become stricter. On the other hand, valuable metals ...
متن کاملThe Smelting of Manganese Carbonate Ore
The practice of manganese ferroalloy smelting has traditionally been based on utilising oxide ores which typically contain a high level of manganese. This preference for oxides has even been extended to the modification of natural carbonates into nodulized oxides. However smelting practices developed over the past 30 years have created a market for natural manganese carbonate ores, driven in pa...
متن کاملHistone Methylation in Nickel-Smelting Industrial Workers
BACKGROUND Nickel is an essential trace metal naturally found in the environment. It is also common in occupational settings, where it associates with various levels of both occupational and nonoccupational exposure In vitro studies have shown that nickel exposure can lead to intracellular accumulation of Ni2+, which has been associated with global decreases in DNA methylation, increases in chr...
