Webinar: Leaching critical metals with ASL and NSC to enable their extraction from complex ores and concentrates

Join the Metallurgical Society for their upcoming webinar: Leaching critical metals with ASL and NSC to enable their extraction from complex ores and concentrates.

About this event

Hydrometallurgical treatment of concentrates, ores and materials is a growing global technology. While sulphuric acid is commonly used in extractive metallurgy, it can only be applied to some materials. In order to leach and process more complex feeds, alternative leaching methods must be used. These include NSC and ASL.

Industrially proven and applied nitrogen species catalysed (i.e. NSC) acidic pressure leaching has been utilised to treat a number of ores, concentrates and recycled materials. The alkaline sulphide leaching (i.e. ASL) system is essentially a mixture of sodium sulphide and sodium hydroxide with other meta-stable alkaline species as required, a very selective lixiviant for the distinct leaching of tin, gold, antimony, arsenic, tellurium, silver and mercury.

This webinar will review the chemistry of both NSC and ASL, and will discuss some of the industrial applications of these leaching processes.
