Environmental Guidelines for Aluminum Manufacturing
At the bauxite production facilities, dust is emitted ... salt slag. Particulate emissions, possibly containing heavy metals, are also associated with secondary aluminum production. Pollution Prevention and Control ... recycling to the process and use of rain water in the process.
Aluminium salt slag characterization and utilization A
May 30, 2012 The salt slag recycling process operated by Befesa Escorias Salinas SA enables the recovery of free metal and flux salts, thus creating a product made up mostly of aluminium oxide. The first stage of the process is the mechanical grinding, whose target is the extraction of metallic aluminium from the salt slag and the reduction of particles to an optimum size to ensure the total dissolution of the salts.
Environmental Problems Associated With Recycling
The salt cake, or dross, that results from recycling aluminum must be disposed of very carefully in order to protect the environment. Engineers have put effort into trying to figure out different ways to solve this problem. One way is to reduce the amount of salt cake that is produced during the recycling process.
Bauxite The principal ore of aluminum
Bauxite is the principal ore of aluminum. The first step in producing aluminum is to crush the bauxite and purify it using the Bayer Process. In the Bayer Process, the bauxite is washed in a hot solution of sodium hydroxide, which leaches aluminum from the bauxite.
Macquarie Harbour Mining Provides Update on Salt Slag
Dec 14, 2010 Alreco processes all of the aluminum salt slag produced in Australia under contracts with Alcoa Australia Rolled Products Pty Ltd, a wholly-owned subsidiary of Alcoa, Inc. and Sims Aluminium Pty Ltd, a wholly owned subsidiary of Sims Metal Management Ltd. Alreco also processes other wastes for Sims, including non-salt slag and aluminum dross.

Barite miners in Nigeria receive government boost call
Nigerias barite sector is hoping to enter a new era of development that will enable it to compete more favourably with the dominant and superior quality barite imports. The Nigerian government recently launched its Economic Recovery and Growth Plan, of which one of its main targets is the mining sector, and in particular, the stimulation of
Chapter 2 Production and Processing of Aluminum
the 19th century, is by far the most important process used in the production of alumi-num oxide from bauxite. The process has been refined and improved since its inception. Fig. 2.2 shows that the production of alumina is a complex chemical process. The alu-mina content of bauxite ores varies from one deposit to another, and methods of treat-
