as pyrites. In a typical pyrytic gold ore, the gold is encapsulated within an iron sulfide crystal structure. highly oxidized ores generally do not respond well to flotation. advantages of the flotation process are that gold values are generally liberated at a fairly coarse particle size which means that ore grinding costs are minimized.
this method of gold recovery is the preferred method for treating low-grade gold ores because of its low cost. between of the gold recovered each year from primary sources is extracted by this technique. the advantages of this process are: simplicity
highly abrasive ores, such as those in the gold industry, can consume about to kg of grinding media per ton of ore mille. As a result, grinding media replenishment is one of the highest above-the-ground consumable cost for mines therefore an improvement in wear characteristics and life, or decrease in price of grinding media, can

jan 01, 2005 background. for the past 100 years the key element in the processing of gold ore has been the cyanidation process. over the years steady improvements have occurred in equipment design; milling has evolved from stamp mills, through tube mills and ball mills to the large semi-autogenous grinding and fullyautogenous grinding circuits in modern gold plants.
We investigate the performance of sample preparation of gold ores using vibratory mills in common use in mineral analytical laboratories. the main criteria for effective grinding are using reduced grinding charge masses ca. 50% of nominal bowl capacity and using a grinding aid to prevent caking. We show that gold
