In addition, Eric et al. [23] investigated the flotation performance of gold in porphyry copper-gold ore by first-order flotation kinetics, which indicated that an increase in flotation time of copper rougher stage cannot result in the increase in gold recovery and some gold particles can only be recovered by pyrite flotation. However, none of ...

Effects of Variation in pH In the earlier tests, the pH was kept at 11. Chalcopyrite is always flotable in oxidizing environment ...
The first pneumatic-flotation plant in this country was erected by me in February 1914 for the National Copper Company at Mullan, Idaho, a description of which has already been published. The results were fully up to expectations from the very start. This plant consists of 8 rougher and 2 cleaner cells and treated 500 tons per 24 hours.
In the Americas, most copper production occurs in Chile. This is followed by Peru, the USA, Mexico, and Canada. Regulatory changes across the Americas are impacting water use by the …
This is an article in the field of mineral processing engineering. Copper is an important non-ferrous metal resource. With the increasing reduction of easily processed copper sulfide, the development and utilization of copper oxide is an important content of research in the mining field. Flotation is the main method to treat copper oxide.
the flotation recovery of Ni, Cu and Co from a nickel-copper sulphide ore. The effect on flotation performance of various parameters such as pH, collector dosage, % solids and depressant dosage at different levels was investigated. Therefore, the main objective of the study was to optimize the process parameters for the flotation of base metals ...
