The mineralized zones at the Lindero deposit form a semi-circular shape about 600 m in diameter which extends to a depth of 600 m, consisting of four different zones at the surface. Distribution of the gold–copper mineralization at Lindero shows a strong relationship to lithology, stockwork veinlets, and alteration assemblages.

Nov 10, 2016· The HPGR is properly regarded as one of the most important recent developments in the field of size reduction. This success is mainly associated to its improved energy efficiency, grinding capacity, lower sensitivity to grindability variations and higher metal recovery in downstream processes compared with conventional grinding technologies such as ball mills and cone crushers.
HPGR or high-pressure grinding rolls have made broad advances into nonferrous metal mining. The technology is now widely viewed as a primary milling alternative, and there arc a number of large installations commissioned in recent years. After these developments, an HPGR based circuit configuration would often be the base case for certain ore types, such as very hard, abrasive ores.
