Autoclave leaching of Zinc, Copper and Nickel bearing ores

PIONERA BioPolymers have been used for years as sulfur dispersants in autoclave leaching. Dispersing sulfur, clay and gypsum away from sulfide ore particles increases metal recoveries and can reduce leach times.

Screening tests in a laboratory autoclave installation have shown that PIONERA BioPolymers increase the metal recovery in leaching circuits and that PIONERA BioPolymers perform differently depending on individual circumstances.
