Advantages of batch cleaner flotation recoveries for copper gold and molybdenum

copper-molybdenum oresrecovery of copper is by standard flotation reagents identified in the copper ore flotation description. molybdenum will float naturally with the copper but can be crowded in the froth by the copper mineralization and use of a moly collector (such as diesel oil, kerosene, refined oils, pine oil or xanthate ester) enhances its floatability. indiana au-cu golden arrow resources corporationprevious preliminarly metallurgical test work reported rougher cleaner (flotation) gold recoveries in sulphide mineralization of over 85%, with a maximum of 97%, and copper recoveries ranging from 90% - 96%, indicating the potential to develop a gold-copper flotation circuit to process sulphide mineralization. seabridge seeks base metal major for ksm development in the pfs, a conventional mill is planned with copper-gold-molybdenum bulk rougher flotation followed by pyrite flotation to recover gold. the bulk rougher concentrate will be reground and passed through three stages of cleaner flotation to produce a copper-gold-molybdenum bulk cleaner concentrate. estimation of copper and molybdenum grades and recoveries in estimation of copper and molybdenum grades and recoveries in the industrial flotation plant using the artificial neural network. ebrahim allahkarami 1, omid salmani nuri 1, aliakbar abdollahzadeh 1,2, bahram rezai 1, mostafa chegini 1 molybdenum ore processing by flotationmetallurgical contentthe molybdenum process flowsheetgrindingcoarse flotation circuitregrind circuitfine flotation circuitconcentrate treatmenttailingsflotation of molybdenite from copper this molybdenum flotation circuit, based on 250-500 tons per 24 hours is designed for low-grade molybdenum ore having high-grade streaks and with pyrite-quartz gangue. cleaner flotation copperacid soluble copper vs caving footprint outline predetermined liberation size and then subjected to two or three stages of cleaner flotation to produce a final flotation concentrate. cleaner flotation tailings is an intermediate product and is recycled within the flotation circuit. many ores contain multiple valuable. get price molybdenum flotationa molybdenum flotation case study with about 6% of the molybdenum contained in the feed is present as an oxide form and about 90% of this is not recovered to the flotation concentrate. recovery of molybdenum into the rougher concentrate varied between 90 to 95% at a concentrate grade of 2.5 to 3.7% molybdenum. improved copper and gold recovery at robinson colorvalue along with byproduct gold and molybdenum. copper-gold concentrates produced at robinson are transported by truck from the mine site about 210 km to east wendover, utah. the concentrate is then railed to west coast port facilities for sea transport. figure 1. kghm international's robinson mineruth pit ore mining molybdenumthis molybdenum flotation metallurgical program consisted of performing one rougher and four batch cleaner flotation tests on the sample of sulphide ore. the nominal primary grind p80 selected for this series of tests was 150181;m. the cleaner tests were designed to investigate the effect of a regrind stage between rougher and cleaner flotation. introduction to mineral processingadditional copper collector is often added to the scavenger flotation cells and may be added at several other points. the froth, enriched in copper and molybdenum, is removed from the flotation roughers and scavengers. this enriched material is now called the rougher concentrate or cleaner feed. the combined rougher-scavenger concentrate may be
