Global Aluminum Industry Production ANSI Blog

Nov 15, 2017 · However, in September 1981, only 1,232,000 metric tons of aluminum reportedly were produced, while, in September 2017, the world saw 4,927,000 metric tons of aluminum created through primary production. The reasoning for this difference is the emergence of aluminum primary production in regions that had no or little influence on the market.

Aluminium production process

The pure form of aluminium does not naturally occur in nature, so remained largely unknown until as recently as 200 years ago. Creating aluminium using electricity was first developed in 1886 and is still used to this day. The aluminium production process starts with the mining of bauxites, an aluminium rich mineral in in the

Aluminium smelting Wikipedia

Primary aluminium is aluminium tapped from electrolytic cells or pots during the electrolytic reduction of metallurgical alumina (aluminium oxide). It thus excludes alloying additives and recycled aluminium. Primary aluminium production is defined as the quantity of primary aluminium produced in

Current Efficiency Aluminum Production

In an aluminum reduction cell three important figures need to be considered. First, current efficiency is the ratio between the actual amount of aluminum produced and the theoretical one. The ratio is alway less than 1 because some of the metal produced is reoxidized in the form of alumina. The specific energy consumption in kWh/kg Al represents the amount of electrical energy to be consumed
