| Abstract Scope |
The Starved Acid Leaching Technology (SALT) uses reduced amounts of sulfuric acid to leach a portion of the nickel and cobalt from lean ore materials. The use of acid must be economic with respect to the nickel and cobalt extracted. Lean resources of saprolite nickel laterite ores may become economic through application of SALT. The SALT process can be tailored to recover various intermediate products including mixed hydroxide precipitate (MHP) or mixed sulphide precipitate (MS). The current development of the SALT process and the prospects for refining MHP or MS to high value nickel and cobalt products will be presented. The SALT technology applied to lean resources may increase the supply of nickel and cobalt for battery material manufacture to meet the demands of electrification in the transport sector. |
