  • Gold Extraction Recovery Processes

    2016-2-29  The ore body formation affects the mining method and the sequence of extracting different zones so that the beneficiation process can be effective. Changes in ore properties, such as ore gold distribution and hardness have influence in gold liberation and consequently will be affected the recovery process. For example, orebodies containing clays have problems due to the excessive amount of fine material liberated during the comminution process

  • Gold extraction process – Kivu Mineral Mining Company

    The mineralized rock at Kivu Mineral Mining would require multiple steps in processing to extract the gold. Mineralized rock is first crushed, then ground in large mills to create a fine, silt-like powder. The gold-bearing minerals are then separated from other materials using a process called “flotation.” A process called “pressure oxidation” is used to oxidize the gold-bearing materials.

    Amalgamation-Gravity Separation Combined MethodGravity Separation (Amalgamation)-Cyanidation Leaching Combined MethodSingle Flotation MethodGravity Separation (Amalgamation)-Flotation Combined MethodDirect Cyanidation (All-Slime Cyanidation) MethodFlotation-Cyanidation Combined MethodFlotation-Roasting-Cyanidation Combined MethodConclusionThis kind of gold processing method includes amalgamation before gravity separation process and gravity separation before amalgamation process. Gravity separation before amalgamation process is mostly used for the extraction of low-grade alluvial gold or the ore with coarse disseminated grain size and contaminated surface. Amalgamation before gravity separation process is mostly used for simple quartz vein gold-bearing sulfide ore, and when gold is monomer in the ore.
