Abstract
Recent field mapping in two open pits at the Okorusu fluorspar mine in Namibia confirmed the presence of a variety of host rocks that were replaced by fluorite ores. The presence of certain textures in the fluorite ores can be used to identify the original host rock that was replaced. The character of the original host rock prior to fluorite replacement, in turn, has a significant controlling influence upon the beneficiation problems that are experienced for those ores.
