Bath quantitative XRD control at Russia aluminium smelters

Pulmonary function in aluminium smelters.

Two studies were conducted at an aluminum smelter employing 113 male workers in the smelting process. Twenty one of the 111 men in the first study experienced chest tightness more often than once a week and had a higher prevalence of cough, dyspnoea, and nasal symptoms but not of positive skin test responses than symptomless men. Lung function in these men did not differ significantly from that...

Agile Manufacturing for ALUMINIUM SMELTERS

An Evaluation of Xrd and Xrf Methods Used in an Aluminium Bath Analysis

The paper deals with the application of X-ray fluorescence and diffraction for the routing control of a chemical content of an electrolysis cell in aluminum reduction plants. Among two approaches XRD meets technological requirements on accuracy, time limit and the cost of analysis. XRF demonstrates insufficient accuracy because of sample preparation problem.

Optimised Cell Batching for New Zealand Aluminium Smelters Ltd

New Zealand Aluminium Smelters Ltd operates a smelting facility at Tiwai Point near Invercargill. The smelter produces aluminium by the electrolytic reduction of alumina in 650 cells. The cells are laid out in long lines and are grouped into tapping bays. The purity of the aluminium varies from cell to cell depending on a number of factors including the age of the cell, the purity of the alumin...
