how to operate gold flotation

Gold ore whose types of deposits are diverse and complex is the mineral assemblage of gold. With features of chalcophile affinity and high melting point, the gold ore includes conglomerate type, porphyry type, quartz vein type and volcanic rock type, etc.

Flotation plant is widely used in various fields of ore dressing industry. For example, the separating of gold ore, silver, galena, sphalerite, chalcopyrite, chalcocite, molybdenite, pyrite, nickel sulfide mineral, malachite, cerussite, smithsonite, he

Gold Flotation Process 12 replies There are mechanical devices to deaerate the froth and break it Some reagents are also able to break stable froth and have been used depending on what is causing the excessive froth The main inputs are fine hydrophobic minerals process water and reagents

GOLD RECOVERY BY FLOTATION A test on a sample crushed to pass a screen of 120 holes per linear inch containing 37 gold and 48 copper gave a recovery by flotation alone of 90 of the gold and 985 of the copper but left 8 gold in the tailing The concentrate carried 44 insoluble matter which could be reduced by retreatment

Who would think that Selective Flotation of copper gold zinc or any metal would required that one must be able to feel pain and recognized andor admit when it hurts Flotation masspull is a process that is often misunderstood a learner’s mistake made by nonoperating types You do not need to pump anything in the lab In selective flotation less is more

Flotation will frequently be used when gold is recovered in conjunction with other metals such as copper lead or zinc Flotation concentrates are usually sent to an offsite smelting facility for recovery of gold and base metals Cyanide leaching is frequently used in conjunction with flotation
