gold ore mineral processing

Gold Process Mineralogy

Process mineralogy is often used to predict the response of a gold ore to the various candidate process. In addition, during the processing of a gold ore, periodic mineralogical analyses of ore feed and mill products are needed to determine the nature of the problem if the gold recovery is lower than expected. Therefore, a routine process mineralogical study of gold ores normally includes some or …
