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. As the amount of fine particles/clays varies, the quantity of moisture has to be altered in real time. The measurement of agglomerate electrical conductivity is used for this. Moisture is adjusted to reproduce a value of conductivity established previously and is the guiding parameter.
