The article presents the developed criteria for the technological typification of gold ores to optimize a method for predicting the ores technological features of ores of gold deposits at the early stages of exploration. These criteria are necessary for mineralogical and technological express-evaluation which allows geological companies to reduce financial cost and decide whether to continue exploration work. So far, previous research of different authors focused on patterns of technological typification of gold ores for specific genetic types of deposits. However, there are no generalizing papers on this subject.
The authors have studied 7 gold deposits. The research included comprehensive mineralogical and technological analysis. The results revealed the dependence of technological properties on the material composition. Furthermore, it was found that there is no correlation between a genetic type of ores and choice of beneficiation scheme. The recently discovered Sikakangas ore occurrence located in western Finland was studied to verify the results. A prediction about the most optimal method of ore beneficiation for Sikakangas deposit based on a comparison of the analysis results and the criteria previously developed for other deposits has been made. The technological experiments confirmed the authors’ hypothesis.
Finally, it should be noted that the developed criteria have turned out relevant for their further application in predicting the method of ore benefication for gold deposits with different genetic types
