US3827557A Method of copper sulfide ore flotation

Mixed concentrate is obtained by flotation of two useful minerals together and then separated from a single concentrate called partial mixed flotation process This is the most widely used process in production When the grade of copper molybdenum copper lead copper zinc lead in the raw ore is low this kind of process is often used The variability of the Kansanshi mixed ore in terms of total copper and acid soluble copper grades has a major impact on the flotation recovery In March 2011 three Blue Cube MQi inline mineral quantifier analysers were installed on the mixed ore flotation feed concentrate and final tails respectively In this study the flotation of oxidized copper ore obtained from Ergani Copper Mining Company in Turkey was performed This ore contains 203 copper 015 cobalt and 373 sulfur An effective processing method has not been found to recover copper and cobalt from this ore which has been stockpiled for 4045 years in the idled plant
