WhatsApp: +86 18203695377The comparison with a conventional grinding circuit with SAGs and ball mills returns a 21 % lower energy demand and annual operating cost savings of almost 15 mill. US [5]. The applications for hard rock comprise besides copper ore, gold ore, ore in the platinum group metals (PGM), molybdenum ore as well as zinc/lead ore.
WhatsApp: +86 18203695377Autogenous Mill. Autogenous mill is a type of grinding equipment that crushes material by mutual impact, grinding and peeling effect among material grains. In 1880, cylindrical grinding mill was invented. In 1899, it was used at a gold mine. Since then, it was discovered that autogenous grinding of ore is possible.
WhatsApp: +86 18203695377Publisher Summary. For the vast majority of ounces of gold produced, comminution costs in the form of power, grinding media, and liners represent the single largest cost category of milling. Since, semiautogenous grinding (SAG) ballmill circuits represent the single largest type of gold milling comminution circuits, the chapter focuses on SAG.
WhatsApp: +86 18203695377A few months ago, an Egyptian customer Karam Kadree asked us about a ball mill for gold ore. The customer processes 60 tons raw gold ore per hour. The material is crushed to less than 25 mm and needs to be ground to 85 mesh. We recommended to him a ball mill of Ф2400 × 4500. After a period of transportation installation and use, customers are ...
WhatsApp: +86 18203695377While the total grinding capacity was only utilised to 85 %, the ball mill already absorbed MW of MW. During the last years the process circuit also had to be adapted to changes of ore mineralogy. Coarser gold liberation size the fines of grind changed from originally 80 % < 74µm to 80 % < 130 µm. Gold enrichment was therefore ...
