Gold Processing,Extraction,Smelting Plant Design

Gold ore Prominer maintains a team of senior gold processing engineers with expertise and global experience These gold professionals are specifically in gold processing through various beneficiation technologies, for gold ore of different characteristics, such as flotation, cyanide leaching, gravity separation, etc, to achieve the processing plant of optimal and costefficient process designsThe process is applicable directly to gold bearing sand, and to goldbearing rocks after crushing The crushing is effected by stonecrushers, rollingmills, and stampmills The washing is carried out either by subjecting the material to the prolonged action of flowing water, or by mechanical agitation with water in deep iron pans or " cradles"Extraction of GoldJ Zhang et al, Processing technologies for goldtelluride ores 3 ing roast, carburizing roast, and sintering or blast roasting The high temperature can sufficiently decompose the tellurides and leave behind the valuable gold residueProcessing technologies for goldtelluride ores
