Feasibility study for the implementation of a fine crushing cycle using HPGR technology in the Assarel Concentrator in order to increase the ball mills throughput of flotation feed with passing 80 % - 0.100 mm, including complex evaluation of the entire ore processing flow sheet in the Assarel Concentrator (excluding the Coarse Crushing Sector) І.
estimated practical minimum energy consumption; suggestions included the implementation of best pra ctices and the adoption of energy efficient mining and mineral processing technologies such as advanced blasting techniques, high pressure grinding rolls (HPGR) and stirred mills (U.S. DOE, 2007) .
HPGR product the improved grindability will result in significant cost savings for energy and from reduced labour and maintenance around fewer operating ball mills. This is especially advantageous in operation where power is a costly item, or where it is necessary to maintain the plant capacity where harder or leaner ores are encountered.
Future circuits may see increasing use of high pressure grinding rolls (Rosas et al., 2012). Autogenous grinding or semiautogenous grinding mills can be operated in open or closed circuit. However, even in open circuit, a coarse classifier such as a trommel attached to the mill, or a …
