9 GOLD MINES AND IMPACT OF HEAVY METALS ON THE

In this method or in this procedure the ore is directly transferred from the jaw crusher to the ball mill. The ball mill has the maximum amount of share in the steel balls which helps in the assistance in the grinding procedure (Flachier & Lanec,2001). Water is added inside the ball mill and the reduction of the ore procedure starts.

Ore Mineral - an overview | ScienceDirect Topics

Ages calculated from Pb–Pb isochrons are generally imprecise, most likely because of the complexity of Pb isotopes and open-system behavior of both U and Pb in many systems (e.g., Jahn and Cuvellier, 1994). Therefore, use of Pb–Pb as a geochronological tool for ore geology has been replaced by more telling techniques in recent years.
