  • Guide of Alluvial Gold Mining Process and Alluvial Gold

    Gravity separation by chute used in the alluvial gold mining process is featured with simple structure, large processing capacity and low comprehensive cost In the production, the selection of alluvial gold mining process and alluvial gold equipment need to be determined according to the specific ore properties and characteristics1 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 semiautogenous grinding (SAG) and fullyautogenous grinding (FAG) circuits in modern gold plantsMetallurgical testwork: Gold processing options, physical1 Introduction The governing method for gold ore processing has been cyanide leaching since the late 19th century (Marsden and House, 2006)After decades of active development of the process for various types of ores and concentrates, there are several different hydrometallurgical flowsheets for cyanide leachingDesigning gold extraction processes: Performance study of
