  • Determine the Proper Grind Size for Gold Ore

    · Without mineralogy, estimating the optimum Grind Size for Gold Ore Sample is most conveniently made by Laboratory Testing and the agitation leaching method, and it will be necessary to make up 3 or 4 bottle charges in order to have enough ore* for the subsequent screen analysis Take an average sample of the ore and grind on the bucking table to pass No 30 sieve Weigh up 4 lots ofGold Ore Grinding Sizing Several authors have demonstrated improved liberation on copper sulphide, iron sulphide and native goldcontaining ores after microwave treatment and subsequent grinding Amankwah et al, 2005, Andriese et al, 2012, Wang and Forssberg, 2005Other studies have also demonstrated increased flotation recovery and concentrate grade attributed to enhanced liberationGold Ore Grinding SizingThe results are consistent with the fact that gold dissolution increases with the decreasing particle size but results also indicate that gold dissolution of the ore within a size interval is not significantly affected by the grinding time used for the ore size reduction Results also show a good dissolution of the gold contained in the finesize fractions without oxidation and lead nitrateEffect of Particle Size and Grinding Time on Gold
