Gold has characteristic of rare, stable value, precious and so on, it plays an important role in social and economic life. Generally it can be divided into gold placer and rock gold mine. In gold dressing plant, gold placer enrichment usually adopts gravity separation, and for rock gold ore, in addition to the gravity separation, there are flotation, cyanide leaching, heap leaching, amalgamated sorting process, etc. Here is a brief introduction of the process of gold dressing plant processing rock gold.
Gold grains in rock gold ore embedded in the rock or disseminated and associated with rocks. When sorting must first adopt certain crushing grinding process makes the gold grains to monomer dissociation, then choosing suitable sorting means for separation and enrichment. Typically the production process of gold mineral processing plant can be divided into crushing, screening, grinding, sorting. The crushing operation mainly has two closed-circuit process and three sections of a closed circuit. Crushing operation adopts jaw crusher or gyratory crusher, and the crushing ratio is three to four, the size of crushing production is 250 to 320mm; the middle-age crushing and fine crushing adopt cone crusher and jaw crusher and the crushing ratio is four to six. Screening operations is provided at the end of a crushing operations, and according to the production need, check screening or pre-check screening are designed and the final crushing granularity needs control in eight to fourteen mm. Undersize qualified products is sent to the grinding workshop. Owing to ball mill has weak control ability on grinding granularity, so the ball mill is usually used with hydraulic cyclone or spiral classifier to constitute a closed circuit operation. According to actual need of gold dressing plant, grinding process is designed for two full closed circuit or a closed circuit grinding process. Product reached the required grinding fineness will be sent to sorting plant, and as required adopt gravity separation, flotation, cyanide leaching, heap leaching, mixing mercury method or means of several joint separation and enrichment process.
