ASD is used to depress copper and iron sulfides in the copper/moly flotation circuit. It is also used as a sulfidizing agent to treat oxide ores. ASD can be used by itself or in conjunction with NaHS.
The effect of sulphite ions on the xanthate-induced flotation of copper-activated pyrite has been studied. Various techniques have been used to identify the plausible mechanisms of interaction of sulphite with both collector and pyrite surface. It was found that sulphite depressed the xanthate-induced flotation of copper-activated pyrite with nitrogen or air purging at pH 7.

May 30, 2016· In this scenario, response of the ore to copper activation may not be easily predicted. To explore the possibilities, flotation with various dosages of copper addition was investigated for this ore with specific interest in how the nickel recovery responds. The responses of copper, iron, cobalt and quartz were also monitored.
results and can successfully analyse total copper (TCu), acid soluble copper (ASCu), sulfur and iron. Analysers were installed on the feed, concentrate and tails lines and provide data at 15 second intervals. This is a first in the Zambian base metals industry and is aimed at optimising the recovery of copper in the flotation circuit. 1. Background
Copper and mercury results at the continuous pilot scale confirmed those obtained in batch testing. Gold recovery from the pilot leach residue was also assessed with elemental sulphur flotation of the residue offering 85% recovery of the precious metals to the flotation concentrate and the most favorable net
Outotec SkimAir® flash flotation. Due to the higher SG of sulphide and precious metal containing minerals there is a strong likelihood that they will report to the hydrocyclone underflow stream despite being in a suitable size range for flotation. By recovering these particles from the circulating load it prevents them reporting back to...
Overview Copper Ore Flotation Processing Plant is mainly composed of jaw crusher, ball mill, spiral classifier, magnetic separator, flotation machine, ore concentrator and dryer machine combining with ore feeder, bucket elevator and belt conveyor which formed a complete ore beneficiation production line.
Copper mining in the United States has been a major industry since the rise of the northern Michigan copper district in the 1840s. In 2017 the United States produced 1.27 million metric tonnes of copper, worth $8 billion, making it the world''s fourth largest copper producer, after Chile, China, and Peru .

Application Note pH Control in Copper Flotation for Maximized Product Yield Background Copper ore may be separated from crude ore using a flotation pro-cess that takes advantage of the physical (as opposed to chemical) properties of small copper ore particles. To maximize the copper yield, pH control is necessary in the flotation tanks.
The copper (II) ion in the chalcopyrite is reduced to copper (I) sulfide which is reduced further to copper metal in the final stages. The iron in the chalcopyrite ends up converted into an iron (II) silicate slag which is removed. Most of the sulfur in the chalcopyrite turns to sulfur dioxide gas.
