Agglomeration Control For Heap Leaching

ABSTRACT The agglomeration of ore has as its main objective to form a uniform and highly permeable heap for leaching. Poor agglomeration itself is the result of the incorrect dosage of agglomeration moisture. This article is based on the experience of Minera Cerro Verde in the development and application of a quantitative method to control moisture during agglomeration.
